  • How does Dirofilaria immitis infection impact the health of dogs referred
           to cardiology care

    • Authors: Nathália Marques De Oliveira Lemos , Bruno Alberigi , Norma Labarthe, Fabiana Batalha Knacfuss, Cristiane Divan Baldani, Marta Fernanda Albuquerque da Silva
      Abstract: Dirofilaria immitis is a nematode that can cause a disease that may present clinical signs from severe to absent. When dogs are symptomatic, the clinical signs are cardiorespiratory and nonspecific, which may be misleading. This study aimed to demonstrate the clinical presentations to cardiac care by evaluating 26 dogs subjected to clinical examination, complete blood count (CBC), specific tests for D. immitis infection, chest radiography, and echocardiography. Among them, 11 (42.3%) dogs were infected and 15 (57.7%) were non-infected. Most dogs presented with coughing (65.4%) and abnormal lung sounds (81%) independent of infection. Murmur at the tricuspid focus was present in 26.9% of the dogs, of which 57.1% were infected. Echocardiography revealed tricuspid regurgitation in 30.8% of the dogs and pulmonary regurgitation in 46.1%, of which 37.5% and 50% were infected, respectively. Worms were detected by echocardiography in 45.5% of the infected dogs. The x-rays showed that the bronchial pattern was present in 45.5% of the infected dogs and in 46.7% of the non-infected dogs. The interstitial pattern was present in 18.2% of the infected animals, in contrast to 6.7% of the non-infected dogs. The CBC results for all dogs were within the reference range, except for platelets. Although similar, the percentage of dogs with thrombocytopenia was higher among infected dogs (36.4%) than among the non-infected (6.7%). These results reinforce that due to the non-specific signs of infection, it is mandatory to perform parasitological assays when evaluating dogs presenting with cardiopulmonary signs.

  • Clinical, epidemiological, and histopathological aspects of breast cancer
           in female dogs at Federal Rural University of Rio de Janeiro Veterinary
           Hospital

      Abstract: This study aimed to evaluate the clinical, epidemiological, and histopathological aspects of canine breast tumors at the Federal Rural University of Rio de Janeiro Veterinary Hospital (VH-UFRRJ) between April 2017 and October 2018. The study included 137 female canine dogs with mammary neoplasia who underwent a mastectomy. The animals were evaluated using a standard form that guided anamnesis and physical examination to assess the tumor’s epidemiology, development, evolution, treatment choice, and disease prognosis. Furthermore, laboratory and imaging tests were performed on the animals to search for changes that suggested metastasis. The average age of the female dogs was 10 years, and mixed-breed dogs (33%) were the most affected, followed by poodles (21%). The inguinal (79%) and caudal abdominal (64%) breasts were the most affected. Approximately 26% of the animals were castrated, 32% had already reproduced throughout their lives, 30% had pseudocyesis, and only 8% used contraceptive methods. The majority were classified as stage I (33%) and stage III (39%) according to the Tumor-Node-Metastasis (TNM) Classification System of Malignant Tumors. In 95 female dogs, 191 nodules were histopathologically evaluated, and 62% of these animals had at least one malignant tumor. Statistically, there was a direct association between tumor size and malignancy. However, other associations, such as age at diagnosis and the degree of malignancy, were not confirmed. Therefore, it can be concluded that tumor size is an important prognostic factor, with tumors >3 cm having an approximately 70% chance of being malignant.

  • Socioeconomic profile, animal care, sanitary practices, and knowledge
           about parasites among owners of domestic dogs and cats treated in Rio de
           Janeiro city

      Abstract: Urban canine and feline populations are expanding worldwide, a fact that can boost the transmission of zoonotic parasites. Thus, it is necessary understanding dog and cat owners’ profile, as well as their perceptions about zoonoses, to develop preventive strategies based on the One Health approach. The aim of the current study is to compare the profile of dog and cat owners, whose domestic pets were treated at Jorge Vaitsman Veterinary Medicine Center, Rio de Janeiro, Brazil. Dog and cat owners, whose domestic pets were treated in the routine service of the aforementioned medical clinic, from August 2017 to November 2018, filled a structured questionnaire comprising closed questions in order to collect information about their socioeconomic profile, hygiene habits, animal care and knowledge about parasites. Comparative analysis was applied to data collected from dog and cat owners, based on using Fischer’s Exact Test or Pearson’s Chi-square. In total, 350 individuals - 244 dog owners and 106 cat owners - filled the questionnaire. The comparative analysis of socioeconomic profile, animal care, sanitary practices and knowledge about parasites did not show differences between dog and cat owners (p≥0.05). Animal vaccination and deworming practices were significantly more prevalent among dog owners than among cat owners (p≤0.05). Overall, respondents have shown lack of knowledge about parasitic zoonoses. Results in the current study have evidenced the need of mediating and promoting information about potentially zoonotic parasitic agents among domestic pet owners, as well as the key role played by veterinarians as mediators of primary prevention measures against these agents.

  • Clinical and blood count findings in dogs naturally infected with
           Dirofilaria immitis

    • Authors: Alexandre José Rodrigues Bendas, Bruno Alberigi, Suzane Galardo, Norma Labarthe, Flavya Mendes-de-Almeida
      Abstract: Dirofilaria immitis is a nematode that infects canids worldwide as well as other mammalian species, including humans. Worms and dogs are well adapted to one another, making dogs the best urban host for the parasite. Nevertheless, 30% of dogs do not sufficiently present microfilaremia, that is, the low larval load impairs transmission by mosquitoes and diagnosis by its detection in the blood samples. Therefore, the canine diagnosis must always include a microfilaria test and serological tests to detect adult worm antigens. To describe the clinical findings in naturally infected dogs in Rio de Janeiro, 34 dogs were included in the study. All dogs were evaluated for history, anamnesis, physical examination, complete blood count (CBC), D. immitis testing for antigens (ELISA test SNAP 4Dx Plus®), and microfilarial burden. The most frequent complaint from the owners was coughing (14.7%, 5/34). The most common CBC finding was eosinophilia (29.4%), followed by thrombocytopenia (26.5%) and neutrophilia (14.7%). Of the 34 animals, 91.2% were microfilaremic, with a mean count of 11.939 microfilaria/mL. Veterinarians working in areas endemic to D. immitis should always undergo screening tests and pulmonary auscultation, and increased expiratory sounds, even in the absence of coughing, can be considered a sign of the disease, along with eosinophilia, thrombocytopenia, and neutrophilia.

  • Canine rabies in Belford Roxo City, Rio de Janeiro, Brazil: a case report

    • Authors: Pedro Cupolillo de Faria, Rafael Moreira Ancora da Luz, Clayton Bernardinelli Gitti
      Abstract: Rabies is a highly lethal disease and is considered one of the most important zoonoses worldwide. In Brazil, the rabies cycle in domestic animals is under control. However, there is feedback from the wildlife cycle as many bats are present in the cities and rural areas of the country. This paper reports a case of a dog receiving veterinary assistance that presented with misbehavior and other unusual signs. After clinical evaluation by two veterinarians and a period of hospitalization to perform tests and treatment, the dog died, and the Municipal Health Department was contacted due to the suspicion of rabies. After laboratory testing and sample analysis, the diagnosis of rabies was confirmed. This case demonstrates the importance of veterinarians’ qualifications in performing clinical and laboratory diagnoses, such as their knowledge concerning surveillance measures and preventive steps before and after exposure. Reinforcing the significance of maintaining vaccination coverage for rabies and promoting public and private vaccination campaigns in areas that lack vaccination campaigns are useful.
