  • Calbindin D28k distribution in neurons and reactive gliosis in cerebellar
           cortex of natural Rabies virus-infected cattle
    • Authors: Verdes, J. M; de SantAna, F. J. F, Sabalsagaray, M. J, Okada, K, Calliari, A, Morana, J. A, de Barros, C. S. L.
      Pages: 361 - 368
      Abstract: Rabies has been an enigmatic disease because microscopic findings in central nervous system tissues do not always correlate well with the severity of the clinical illness. Immunohistochemical staining of the calcium-binding protein calbindin (specifically CbD28k) seems to be the technique most used to identify Purkinje neurons under normal and pathological conditions. In the present work, we evaluated CbD28k immunoreactivity in the cerebellar cortex of normal and natural Rabies virus (RABV)-infected cattle. We examined brains from 3 normal cows and from 6 crossbreed cattle with a histologic diagnosis of rabies. Samples were taken from the cerebral cortex, cerebellum, hippocampus, and brainstem. Immunohistochemistry was carried out using the following primary antibodies: anti-RABV, anti-GFAP, and anti-CbD28k. In the cerebellar cortex, RABV infection caused the loss of CbD28k immunostaining in Purkinje cells; some large interneurons in the granular layer maintained their positive CbD28k immunoreaction. The identification of this loss of CbD28k reactivity in cerebellar Purkinje cells of RABV-infected cattle presents a potentially valuable tool to explore the impairment of Ca2+ homeostasis. In addition, this may become a useful method to identify specific molecular alterations associated with the higher prevalence of Negri bodies in Purkinje cells of cattle. Furthermore, we detected the presence of rabies viral antigens in different regions of the central nervous system, accompanied by microglial proliferation and mild reactive astrogliosis.

  • Cilia-associated bacteria in fatal Bordetella bronchiseptica pneumonia of
           dogs and cats
    • Authors: Taha-Abdelaziz, K; Bassel, L. L, Harness, M. L, Clark, M. E, Register, K. B, Caswell, J. L.
      Pages: 369 - 376
      Abstract: Bordetella bronchiseptica frequently causes nonfatal tracheobronchitis, but its role in fatal pneumonia is less recognized. Our study evaluated histologic identification of cilia-associated bacteria as a method for diagnosis of B. bronchiseptica pneumonia. Cases of fatal bronchopneumonia were studied retrospectively, excluding neonates and cases of aspiration pneumonia, minor lung lesions, or autolysis. The study population comprised 36 canine and 31 feline cases of bronchopneumonia. B. bronchiseptica was identified in 8 of 36 canine and 14 of 31 feline cases based on immunohistochemistry (IHC) using serum from a rabbit hyperimmunized with pertactin, PCR testing (Fla2/Fla12), and/or bacterial culture data when available. Of these, IHC was positive in 4 canine and 7 feline cases, PCR was positive in 8 canine and 14 feline cases, and B. bronchiseptica was isolated in 2 of 5 canine and 3 of 9 feline cases tested. Examination of histologic sections stained with hematoxylin and eosin revealed bronchial cilia-associated bacteria in 4 of 36 canine and 5 of 31 feline cases; these were all positive by IHC and PCR. The presence of cilia-associated bacteria had been noted in the pathology report for only 2 of these 9 cases. Thus, the presence of cilia-associated bacteria seems frequently overlooked by pathologists, but is a diagnostically significant feature of B. bronchiseptica pneumonia. A specific diagnosis of B. bronchiseptica pneumonia is important because it suggests primary or opportunistic bacterial pneumonia rather than aspiration pneumonia, and because of the risk of animal-to-animal transmission of B. bronchiseptica, the availability of vaccines for disease prevention, and the potential zoonotic risk to immunocompromised pet owners.

  • Detection of multiple viral infections in cattle and buffalo with
           suspected vesicular disease in Brazil
    • Authors: Laguardia-Nascimento, M; Sales, E. B, Gasparini, M. R, de Souza, N. M, da Silva, J. A. G, Souza, G. G, Carani, F. R, dos Santos, A. F, Rivetti Junior, A. V, Camargos, M. F, Fonseca Junior, A. A.
      Pages: 377 - 381
      Abstract: Vesicular diseases are of high importance for livestock, primarily because of foot-and-mouth disease (FMD), which is a high-morbidity disease that generates direct losses caused by low milk production, weight loss, and indirect losses because of the need for sanitary barriers. Other vesicular diseases are also of importance for livestock because of direct impacts or because their clinical signs may be confused with those of FMD. We report herein the detection of multiple infections in cattle with suspected vesicular disease in the Brazilian states of Amazonas (AM), Mato Grosso (MT), and Roraima. Thirty-seven epithelial samples from cattle and 1 sample from a buffalo were sent to the laboratory for testing for FMDV and similar disease agents. All samples from MT were positive for parapoxvirus (Pseudocowpox virus and Bovine papular stomatitis virus). In addition, 3 samples were positive for Bluetongue virus, and 5 samples were positive for Bovine herpesvirus 1. Among these samples, 1 was positive for all of these 3 agents. Only 2 samples from AM were negative for parapoxvirus. The molecular tests conducted in this study detected multiple infections, with a high prevalence of parapoxvirus.

  • Identification of the major capsid protein of erythrocytic necrosis virus
           (ENV) and development of quantitative real-time PCR assays for
           quantification of ENV DNA
    • Authors: Purcell, M. K; Pearman-Gillman, S, Thompson, R. L, Gregg, J. L, Hart, L. M, Winton, J. R, Emmenegger, E. J, Hershberger, P. K.
      Pages: 382 - 391
      Abstract: Viral erythrocytic necrosis (VEN) is a disease of marine and anadromous fish that is caused by the erythrocytic necrosis virus (ENV), which was recently identified as a novel member of family Iridoviridae by next-generation sequencing. Phylogenetic analysis of the ENV DNA polymerase grouped ENV with other erythrocytic iridoviruses from snakes and lizards. In the present study, we identified the gene encoding the ENV major capsid protein (MCP) and developed a quantitative real-time PCR (qPCR) assay targeting this gene. Phylogenetic analysis of the MCP gene sequence supported the conclusion that ENV does not group with any of the currently described iridovirus genera. Because there is no information regarding genetic variation of the MCP gene across the reported host and geographic range for ENV, we also developed a second qPCR assay for a more conserved ATPase-like gene region. The MCP and ATPase qPCR assays demonstrated good analytical and diagnostic sensitivity and specificity based on samples from laboratory challenges of Pacific herring Clupea pallasii. The qPCR assays had similar diagnostic sensitivity and specificity as light microscopy of stained blood smears for the presence of intraerythrocytic inclusion bodies. However, the qPCR assays may detect viral DNA early in infection prior to the formation of inclusion bodies. Both qPCR assays appear suitable for viral surveillance or as a confirmatory test for ENV in Pacific herring from the Salish Sea.

  • Poisoning of sheep by Vernonia plantaginoides (Less.) Hieron in Uruguay
    • Authors: Dutra, F; Romero, A, Quinteros, C, Araujo, R, Garcia y Santos, C.
      Pages: 392 - 398
      Abstract: Vernonia plantaginoides (Less.) Hieron, previously known as Vernonia squarrosa, is a rhizomatous subshrub with purple flowers that is prevalent in the natural grassland of Uruguay, Argentina, and southern Brazil. We report an outbreak of V. plantaginoides (yuyo moro) intoxication in sheep in Treinta y Tres Department, northeastern Uruguay. A total of 54 of 463 (12%) recently weaned lambs died 2–7 days after entering a natural pasture that had been invaded by sprouting V. plantaginoides. The first cases were found dead. Affected lambs showed marked jaundice, edema of the face, ears, and eyelids, and severe photodermatitis. At the autopsies of 3 lambs, the carcass was yellow, the liver was enlarged with a marked acinar pattern ("nutmeg liver"), and hemorrhages were observed on serous membranes. Microscopic lesions were characterized by diffuse periacinar hepatocellular necrosis and cholemic nephrosis. Three female lambs were experimentally dosed with the aerial parts of V. plantaginoides collected immediately after the outbreak. The lamb that was dosed once with 40 g/kg body weight died after 36 h with severe hepatic necrosis. The lamb dosed with 20 g/kg daily for 4 days showed clinical signs and microscopic lesions in the liver with multiple apoptotic hepatocytes in the periacinar zone. The third lamb, dosed with 30, 17, and 15 g/kg daily over 3 days, respectively, showed transient clinical signs and a rise in liver enzymes, but recovered, and no lesions were found postmortem. These results demonstrate that V. plantaginoides was responsible for severe field outbreaks of poisoning in sheep in Uruguay.

  • Exotic pediculosis and hair-loss syndrome in deer (Odocoileus hemionus)
           populations in California
    • Authors: Roug, A; Swift, P, Puschner, B, Gerstenberg, G, Mertins, J. W, Johnson, C. K, Torres, S, Mortensen, J, Woods, L.
      Pages: 399 - 407
      Abstract: Infestation with nonnative, "exotic" lice was first noted in Washington black-tailed deer (Odocoileus hemionus columbianus) in 1994 and has since then spread throughout the western United States. In California, infestation with the exotic louse Damalinia (Cervicola) sp. was first detected in black-tailed deer from northern California in 2004, and, in 2009, the exotic louse species Bovicola tibialis and Linognathus africanus were identified on mule deer (Odocoileus hemionus californicus) in central Sierra Nevada in association with a mortality event. Exotic lice have since been detected in various locations throughout the state. We describe the geographic distribution of these exotic lice within California, using data from 520 live-captured and 9 postmortem-sampled, free-ranging mule deer examined between 2009 and 2014. Data from live-captured deer were used to assess possible associations between louse infestation and host age, host sex, migratory behavior, season, and blood selenium and serum copper concentrations. Damalinia (Cervicola) sp. and B. tibialis lice were distinctively distributed geographically, with D. (Cervicola) sp. infesting herds in northern and central coastal California, B. tibialis occurring in the central coastal mountains and the Sierra Nevada, and L. africanus occurring only sporadically. Younger age classes and low selenium concentrations were significantly associated with exotic louse infestation, whereas no significant relationship was detected with serum copper levels. Our results show that exotic lice are widespread in California, and younger age classes with low blood selenium concentrations are more likely to be infested with lice than older deer.

  • CD47 expression in cryopreserved equine cutaneous masses and normal skin
    • Authors: Caston, S. S; Cooper, E. E, Chandramani-Shivalingappa, P, Sponseller, B. A, Hostetter, J. M, Sun, Y.
      Pages: 408 - 413
      Abstract: We investigated CD47 expression in cryopreserved sections of equine cutaneous masses and normal skin. CD47 is a cell surface protein expressed on many cell types and overexpressed in some tumors. Interaction of CD47 and signal regulatory protein–alpha (SIRPα) inhibits phagocytosis by macrophages. Formalin-fixed tissues from horses prospectively enrolled in the study were used to establish a histologic diagnosis. Immunohistochemical assays were performed on cryopreserved tissues using anti-CD47 antibodies or IgG control antibodies. CD47 was not expressed on equine normal skin but positivity to CD47 was present in 13 of 24 (54%) masses. Immunotherapy with anti-CD47 antibodies for equine cutaneous tumors that express CD47 warrants further investigation.

  • Development of an equine coronavirus-specific enzyme-linked immunosorbent
           assay to determine serologic responses in naturally infected horses
    • Authors: Kooijman, L. J; Mapes, S. M, Pusterla, N.
      Pages: 414 - 418
      Abstract: Equine coronavirus (EqCoV) infection has been documented in most reports through quantitative qPCR analysis of feces and viral genome sequencing. Although qPCR is used to detect antigen during the acute disease phase, there is no equine-specific antibody test available to study EqCoV seroprevalence in various horse populations. We developed an enzyme-linked immunosorbent assay (ELISA) targeting antibodies to the spike (S) protein of EqCoV and validated its use, using acute and convalescent sera from 83 adult horses involved in 6 outbreaks. The EqCoV S protein–based ELISA was able to reliably detect antibodies to EqCoV in naturally infected horses. The greatest seroconversion rate was observed in horses with clinical signs compatible with EqCoV infection and EqCoV qPCR detection in feces. The EqCoV S protein–based ELISA could be used effectively for seroepidemiologic studies in order to better characterize the overall infection rate of EqCoV in various horse populations.

      Abstract: Salmonella enterica subsp. enterica serovar Gallinarum biovar Gallinarum (S. Gallinarum) and biovar Pullorum (S. Pullorum) are 2 poultry pathogens that cause major economic losses to the poultry industry worldwide. Control of both diseases mainly relies on the adoption of biosecurity programs, and success is dependent on accurate and fast detection. Based on this concept, we developed a duplex PCR assay, targeting 2 chromosomal sequences, which allowed us to precisely identify and differentiate S. Gallinarum and S. Pullorum field strains. This assay was validated by testing genomic DNA from 40 S. Gallinarum and 29 S. Pullorum field strains, 87 other Salmonella serovars, and 7 non-Salmonella strains. The serovar identifier region (SIR) primers produced a fragment only in S. Gallinarum and S. Pullorum strains, whereas the fragment from the ratA coding sequence, which was previously demonstrated to differentiate the 2 biovars, was also amplified from other Salmonella serovars. Our results showed that the combination of both SIR and ratA amplifications could be used to identify as well as to differentiate colonies of S. Gallinarum and S. Pullorum reliably. Thus, we believe this methodology can be a useful ancillary tool for routine veterinary diagnostic laboratories by providing rapid, accurate results.

  • Streptococcus bovis/S. equinus complex septicemia in a group of calves
           following intramuscular vaccination
    • Authors: Clarke, L. L; Fathke, R. L, Sanchez, S, Stanton, J. B.
      Pages: 423 - 428
      Abstract: Organisms previously classified as Streptococcus bovis (i.e., the S. bovis/S. equinus complex) are common in cattle feces, but may also act as opportunistic pathogens. In the current work, Streptococcus infantarius subsp. coli, a member of this complex, was associated of a cluster of calves that died within hours of injection with a modified live viral vaccine. Within 12 h of vaccination of 46 calves at a cow/calf operation, 4 calves had died, 3 calves were ill, and 1 unvaccinated cow was dead. Autopsies were performed on the cow, 2 dead calves, and 1 affected surviving calf, which was euthanized ~24 h after vaccine administration. The animals had similar gross anatomic and microscopic lesions, including subcutaneous and intramuscular dark hemorrhage on the caudal neck, multiorgan ecchymosis and petechiation, and alveolitis to interstitial pneumonia. Gram-positive cocci were in the vasculature of the lung and skeletal muscle, and S. infantarius subsp. coli was cultured from tissues and from the vaccines used on affected animals, but not in vials used on unaffected animals. Together, these findings suggest death caused by streptococcal septicemia and toxemia as a result of contamination.

  • Cutaneous amelanotic signet-ring cell malignant melanoma with interspersed
           myofibroblastic differentiation in a young cat
    • Authors: Hirz, M; Herden, C.
      Pages: 429 - 435
      Abstract: The diagnosis of malignant melanoma can be difficult because these tumors can be amelanotic and may contain diverse variants and divergent differentiations, of which the signet-ring cell subtype is very rare and has only been described in humans, dogs, cats, and a hamster. We describe herein histopathologic and immunohistochemical approaches taken to diagnose a case of signet-ring cell malignant melanoma with myofibroblastic differentiation in a cat. A tumor within the abdominal skin of a 2-year-old cat was composed of signet-ring cells and irregularly interwoven streams of spindle cells. Both neoplastic cell types were periodic-acid–Schiff, Fontana, and Sudan black B negative. Signet-ring cells strongly expressed vimentin and S100 protein. Spindle cells strongly expressed vimentin and smooth muscle actin; some cells expressed S100, moderately neuron-specific enolase, and others variably actin and desmin. A few round cells expressed melan A, and a few plump spindle cells expressed melan A and PNL2, confirming the diagnosis of amelanotic signet-ring cell malignant melanoma with myofibroblastic differentiation in a cat. Differential diagnoses were excluded, including signet-ring cell forms of adenocarcinomas, lymphomas, liposarcomas, leiomyosarcomas, squamous cell carcinomas, basal cell carcinomas, and adnexal tumors.

      Pages: 436 - 439
      Abstract: Our study describes the clinical, epidemiologic, pathologic, immunohistochemical, and molecular aspects PCR of a case of cutaneous pythiosis in a donkey (Equus asinus) from Brazil. During a dry period, the animal grazed for 4 months around a pond where the vegetation remained green. Skin lesions were nodular, multifocal, and disseminated, mainly involving the legs, ventral chest, and mammary gland. On cut surface, there were multifocal to coalescent discrete yellow foci, and occasional small cavitations with a few kunkers. Ulcerative nodular pyogranulomatous and eosinophilic dermatitis with folliculitis and furunculosis were observed histologically. Hyphae were observed in sections stained with Gomori methenamine silver. Immunohistochemistry with Pythium insidiosum antibodies yielded strong immunostaining of hyphae. P. insidiosum DNA was extracted from tissues in paraffin blocks by amplification of a fragment of 105 bp, which targets the 5.8S ribosomal gene. After the diagnosis of pythiosis, the larger skin lesions were excised and treated as second intention healing wounds, which were completely healed 30 days after resection. Small skin lesions regressed spontaneously in ~60 days. The granulomatous inflammation and outcome of the disease in this donkey were similar to cases of pythiosis in cattle.

  • Aneurysm of the cranial mesenteric artery as a site of carriage of
           Salmonella enterica subsp. enterica serovar Abortusequi in the horse

      Abstract: Salmonella enterica subsp. enterica serovar Abortusequi is a pathogen restricted to horses. Our investigation targeted 4 draft horses (9–10 months old) kept on a Japanese farm that had suffered an outbreak of S. Abortusequi abortion. The 4 horses were suspected to be carriers of the bacterium owing to their high agglutination titers (≥1:2,560) in tube agglutination testing. The owners’ on-farm observations confirmed that the horses had no apparent abnormalities, and S. Abortusequi was not isolated from their blood, rectal swabs, or sternal bone marrow fluid at antemortem investigation. However, at autopsy, all horses displayed the following: suppurative aneurysm of the cranial mesenteric artery with heavy infection with Strongylus vulgaris larvae; heavy intestinal parasitic infection with Gasterophilus intestinalis, Parascaris equorum, Anoplocephala perfoliata, and S. vulgaris; and enlargement of the systemic lymph nodes. In each case, large numbers of S. Abortusequi were isolated from the anterior mesenteric artery thrombus. The thrombus isolates harbored a single virulence plasmid, and the pulsed-field gel electrophoresis profiles of the isolates were identical not only to each other but also to those of Japanese enzootic strains of S. Abortusequi. These results reveal that parasitic aneurysms of the cranial mesenteric artery should be considered an important possible site of carriage of S. Abortusequi in horses. The results also suggest high clonality of the isolated serovar in the horse population in Japan.

  • Confirmation of Elsey virus infection in a Queensland horse with mild
           neurologic signs
    • Authors: Agnihotri, K; Pease, B, Oakey, J, Campbell, G.
      Pages: 445 - 448
      Abstract: In 2011, a 2-year-old horse in northern Queensland, Australia, was reported to have developed mild neurologic signs, and a blood sample was submitted for laboratory investigation. Virus isolation was performed using the blood sample, and an orbivirus was isolated. This was confirmed to be a strain of Elsey virus (ELSV) after transmission electron microscopy and nucleotide sequencing. The nucleotide sequence was compared with those in GenBank, and had 100% identity with ELSV previously reported from the Northern Territory, Australia. ELSV is taxonomically closely related to Peruvian horse sickness virus.

  • Glioblastoma with oligodendroglioma component in a ewe
    • Authors: Pintus, D; Marruchella, G, Masia, M, Maestrale, C, Cancedda, M. G, Contu, C, Macciocu, S, Ligios, C.
      Pages: 449 - 454
      Abstract: Herein we describe a glioblastoma partially occupying the telencephalic portion of the left cerebral hemisphere of a Sardinian (syn. Sarda) breed ewe. Microscopically, the mass consisted of a pleomorphic spindle-shaped cell component organized as bundles and numerous small areas of round cells displaying an oligodendroglioma-like aspect. A high number of mitotic figures, large areas of necrosis surrounded by pseudopalisading glial cells, and multiple foci of dystrophic mineralization were also observed. The neoplasm was highly vascularized with glomerular vascular proliferation. Immunohistochemically, neoplastic cells proved to be strongly positive for nestin, vimentin, and olig-2, whereas they were invariably negative for synaptophysin. Few neoplastic cells and reactive astrocytes, mainly located at the edge of necrotic foci, proved to be positive for glial fibrillary acidic protein, whereas glomerular vascular proliferation was clearly positive for factor VIII and vascular endothelial growth factor. Gene sequencing analysis demonstrated homozygous p53 tumor suppressor gene (TP53) point mutations in the DNA-binding domain located in exon 8. The presence of round cells immunoreactive for olig-2 demonstrated that this tumor is a glioblastoma with oligodendroglioma component. Our pathologic, immunohistochemical, and molecular findings largely overlap those previously reported in humans and dogs.

  • Characterization of spinal cord lesions in cattle and horses with rabies:
           the importance of correct sampling
    • Authors: Bassuino, D. M; Konradt, G, Cruz, R. A. S, Silva, G. S, Gomes, D. C, Pavarini, S. P, Driemeier, D.
      Pages: 455 - 460
      Abstract: Twenty-six cattle and 7 horses were diagnosed with rabies. Samples of brain and spinal cord were processed for hematoxylin and eosin staining and immunohistochemistry (IHC). In addition, refrigerated fragments of brain and spinal cord were tested by direct fluorescent antibody test and intracerebral inoculation in mice. Statistical analyses and Fisher exact test were performed by commercial software. Histologic lesions were observed in the spinal cord in all of the cattle and horses. Inflammatory lesions in horses were moderate at the thoracic, lumbar, and sacral levels, and marked at the lumbar enlargement level. Gitter cells were present in large numbers in the lumbar enlargement region. IHC staining intensity ranged from moderate to strong. Inflammatory lesions in cattle were moderate in all spinal cord sections, and gitter cells were present in small numbers. IHC staining intensity was strong in all spinal cord sections. Only 2 horses exhibited lesions in the brain, which were located mainly in the obex and cerebellum; different from that observed in cattle, which had lesions in 25 cases. Fisher exact test showed that the odds of detecting lesions caused by rabies in horses are 3.5 times higher when spinal cord sections are analyzed, as compared to analysis of brain samples alone.

  • Choroid plexus papilloma in a beluga whale (Delphinapterus leucas)
    • Authors: Thomas, C; Mergl, J, Gehring, E, Paulus, W, Martineau, D, Hasselblatt, M.
      Pages: 461 - 463
      Abstract: We report herein a choroid plexus papilloma in a beluga whale (Delphinapterus leucas). This case was positive for choroid plexus tumor marker Kir7.1 on immunohistochemistry. These results and the high conservation of Kir7.1 across species at the amino acid sequence level strongly suggest that antibodies directed against Kir7.1 not only can be employed for the diagnosis of choroid plexus tumors in cetaceans, but are also likely to be diagnostically useful in other animal species.

  • Kir7.1 immunoreactivity in canine choroid plexus tumors
    • Authors: Choi, E. J; Sloma, E. A, Miller, A. D.
      Pages: 464 - 468
      Abstract: Choroid plexus neoplasms are uncommon brain tumors in dogs. Choroid plexus carcinomas often spread diffusely throughout the ventricular system and subarachnoid space and, in aggressive forms, can mimic histologic patterns of other carcinomas, including being embedded in a desmoplastic reaction. Although choroid plexus tumors (CPTs) heterogeneously express pan-cytokeratin, little is known about other markers to identify choroid plexus and their associated tumors. Kir7.1, an inward-rectifier potassium channel, is reported to have high diagnostic utility in human neuropathology to distinguish CPTs from other primary brain tumors and cerebral metastases. To determine Kir7.1 expression in the dog brain, we analyzed the immunoreactivity of Kir7.1 in normal brain, gliomas, ependymomas, CPTs, meningiomas, and carcinomas. In normal brain tissue, the immunostaining was restricted to the choroid plexus where there was robust membrane immunoreactivity along the apical border of the cells with less intense cytoplasmic staining. Similar strong immunoreactivity was detected in 12 of 12 CPTs, whereas 5 of 5 gliomas, 4 of 5 ependymomas, 5 of 5 meningiomas, and 5 of 6 carcinomas had no immunoreactivity. One ependymoma and 1 nasal carcinoma with squamous metaplasia were up to 75% immunopositive, with moderate cytoplasmic and membranous immunoreactivity, but lacking the robust apical immunoreactivity pattern. Analysis for immunoreactivity in a tissue microarray failed to yield any other locations in which immunoreactivity was detected. These results, including the distinctive pattern of immunostaining in CPTs, suggest that Kir7.1 is an excellent marker for CPTs in the dog.

  • Pagetoid reticulosis (epitheliotropic cutaneous T-cell lymphoma) in an
           adult alpaca (Vicugna pacos)
    • Authors: Hasbach, A. E; Stern, A. W.
      Pages: 469 - 472
      Abstract: A 9-year-old, intact female alpaca (Vicugna pacos) was presented for a second opinion with a 1-year history of nonpruritic, multifocal scaling and crusted cutaneous lesions, mainly involving skin on the face, axillae, and ventral abdomen. Clinical abnormalities were limited to the skin, and the alpaca was otherwise healthy. The initial veterinarian had examined the alpaca, found no evidence of ectoparasites with laboratory testing, and had tried several trial therapies including oral antibiotics, ivermectin, and topical use of betadine solution. At the time of presentation, the lesions had neither improved nor worsened with any attempted therapy, and multiple skin biopsies were collected. Histopathology and immunohistochemical staining findings were consistent with the pagetoid reticulosis type of cutaneous epitheliotropic T-cell lymphoma. Our report describes the clinical, histopathologic, and immunophenotypic features of pagetoid reticulosis epitheliotropic cutaneous T-cell lymphoma in an alpaca.

  • Rhabdochlamydia spp. in an Oregon raptor
    • Authors: Jouffroy, S. J; Schlueter, A. H, Bildfell, R. J, Rockey, D. D.
      Pages: 473 - 476
      Abstract: PCR-based approach was used to examine the rate of Chlamydia positivity in raptors from wild bird rehabilitation centers in Oregon. Three of 82 birds were identified as positive for Chlamydia with this PCR. Sequence analysis of 16S ribosomal DNA from 2 of these birds confirmed the presence of DNA from phylum Chlamydiae. One bird was positive for Chlamydia psittaci in both choanal and cloacal swabs. The second bird, a louse-infested red-tailed hawk, had evidence of choanal colonization by "Candidatus Rhabdochlamydia" spp. Our study describes evidence of this Chlamydia-like organism in the United States. This survey also suggests that the carriage rate of C. psittaci is low in raptors in Oregon wild bird rehabilitation centers, and that care must be taken in the design of PCR primers for phylum Chlamydiae such that colonization by insect endosymbionts is not mistaken for an infection by known chlamydial pathogens.
