  • Redesign of the Quality Management System at CENLAC Laboratory based on NC
           ISO/IEC 17025: 2017 standard

    • Abstract: RESUMEN Los laboratorios de análisis de alimentos son los encargados de comprobar la conformidad implicada en la Calidad y la Seguridad Alimentaria, reportar datos confiables y seguros a nivel químico, físico, organoléptico o microbiológico. El Sistema de Gestión de la Calidad (SGC), ajustado a los laboratorios de ensayo, permite demostrar la competencia técnica para realizar ensayos con la capacidad de generar resultados válidos. La edición vigente de la NC ISO/IEC 17025 que se utiliza como referencia para implementar el SGC, presenta un nuevo diseño con requisitos que inducen a los laboratorios acreditados o en vías de acreditación a rediseñar el Sistema de Gestión. El Laboratorio de Ensayos para el Control de la Calidad de los Alimentos (CENLAC) mantiene un nivel de excelencia en los servicios que ofrece a sus clientes a través de la garantía de la validez de los resultados. La presente investigación tuvo como objetivo rediseñar el SGC con la incorporación de nuevas actividades, como son el pensamiento basado en riesgo, la capacitación del personal y el enfoque a proceso en el trabajo diario. Se aplicaron diversos métodos y técnicas: entrevista, observación, encuesta, lista de verificación, método Delphi, matriz DAFO, tormenta de ideas y diagrama Gantt. Como resultados, se obtuvo la implementación de un plan de acción que tributó al rediseño del SGC del CENLAC. Se destacaron la identificación de los riesgos y las oportunidades (incluyendo los de imparcialidad), la definición del alcance del sistema, la elaboración de los objetivos y política de calidad, del compromiso de imparcialidad y del procedimiento de tratamiento al trabajo no conforme.ABSTRACT Food analysis laboratories are responsible for verifying the conformity involved in Food Quality and Safety and reporting reliable and safe data at a chemical, physical, organoleptic or microbiological level. The Quality Management System (QMS) adapted to the testing laboratories, allows demonstrating the technical competence to carry out tests with the ability to generate valid results. The current edition of NC ISO/IEC 17025 standard, which is used as a reference to implement the QMS, presents a new design with requirements to induce accredited laboratories or those in the process of accreditation to redesign the Management System. The Food Quality Control Testing Laboratory (CENLAC) ensures a level of excellence in the services it offers to its clients by guaranteeing the validity of the results. The objective of this research was to redesign the QMS with the incorporation of new activities such as risk-based thinking, staff training and the process approach in the daily work. Different methods and techniques were applied, such as: interview, observation, survey, checklist, Delphi method, SWOT matrix, brainstorming, and Gantt chart. As a result, the implementation of an action plan that contributed to the redesign the OMS of CENLAC was obtained. Risks and opportunities (including those of impartiality) were identified, the scope of the system was defined, the quality objectives and policies were developed, and the commitment to impartiality and the procedure for dealing with nonconforming work were defined.
       
  • Evaluation of population immunity against classical swine fever under
           endemic disease conditions in Cuba

    • Abstract: RESUMEN La peste porcina clásica (PPC), o cólera porcino, es una enfermedad viral multisistémica, altamente contagiosa y de notificación obligatoria a la Organización Mundial de la Salud Animal (OMSA) por la amenaza de su diseminación transfronteriza. Afecta exclusivamente a los suidos domésticos y salvajes, con signos clínicos y lesionales heterogéneos, dependientes de factores del huésped, el virus y el ambiente, que complican su comportamiento epidemiológico. El endemismo prolongado de la enfermedad en Cuba y la sistemática aplicación de la vacunación con una vacuna viva, modificada de la Cepa China (producida por LABIOFAM), han propiciado procesos de selección positiva sobre las cepas circulantes, que explican su clasificación en un nuevo genotipo 1.4 y la aparición de cepas de moderada a baja virulencia, que han complicado la sospecha clínica de los casos; además de la presencia de cerdos persistentemente infectados (pre y posnatalmente), que no responden a la vacunación y eliminan constantemente virus al ambiente. En este escenario, en una provincia de Cuba se caracterizó el perfil serológico de poblaciones de cerdos de granjas tecnificadas y semitecnificadas sometidas sistemáticamente a la vacunación con la vacuna viva modificada de la Cepa China de producción nacional. La detección de anticuerpos contra el virus de PPC se realizó mediante la técnica ELISA (Enzyme-Linked Inmunoabsorbent Assay) (ELISA CSFV Ab Test IDEXX 99-43220). Se constató un bajo nivel de inmunidad poblacional en el territorio con solo 52,4 % de animales positivos de los 7502 cerdos investigados. Los cerdos para reemplazo reproductivo en las granjas genéticas mostraron el mayor porcentaje (79,27 %), incluso respecto a sus progenitores. Las cebas mostraron menor frecuencia de animales positivos respecto a los reproductores, y en general fue mayor en granjas tecnificadas (57,97 %) respecto a semitecnificadas (45,1 %). Las granjas de ciclo cerrado mostraron menor frecuencia de positivos (48,2 %) respecto a las de ciclo abierto y combinado. Los cerdos en convenios productivos semitecnificados mostraron solo 42,66 % de animales positivos y hubo diferencias en dependencia de las granjas de origen. Estos resultados pueden estar asociados tanto a la presencia de animales desprotegidos por fallos vacunales a la vacunación (33 ±3 días de edad) ante la presencia de altos títulos de anticuerpos maternales, como a un alto porcentaje de cerdos infectados pre o posnatalmente que son inmunotolerantes y no responden al inmunógeno, condiciones que favorecen el endemismo de la PPC en ese territorio y requieren la revisión de las estrategias empleadas para el control de la enfermedad. Se resalta la importancia del análisis de estos resultados a 10 años de realizada esta investigación.ABSTRACT Classical swine fever (CSF), or hog cholera, is a highly contagious multisystemic viral disease that is notifiable to the World Organization for Animal Health (WOAH) because of the threat of its transboundary spread. It exclusively affects domestic and wild swine, with heterogeneous clinical and lesional signs, depending on host, virus and environmental factors, which complicate its epidemiological behavior. The prolonged endemism of the disease in Cuba and the systematic application of a live vaccine, modified from the Chinese Strain (produced by LABIOFAM), have led to positive selection processes on the circulating strains, which explain their classification in a new genotype 1.4 and the appearance of moderate to low virulence strains, which have aggravated the clinical suspicion of the cases. In addition, there is the presence of persistently infected pigs (pre- and postnatally), which do not respond to vaccination and constantly shed virus into the environment. In this scenario, the serological profile of pig populations from technified and semi-technified farms, with different productive system (closed and open cycle, and both combined), systematically subjected to vaccination was characterized in one province. Antibody detection against CSFV was carried out by ELISA (Enzyme-Linked Immunoabsorbent Assay) (ELISA CSFV Ab Test IDEXX 99-43220). There was a low level of population immunity in the territory with only 52.4 % of positive animals out of 7502 pigs tested. Pigs for reproductive replacement in genetic farms showed the highest percentage (79.27 %), even with respect to their progenitors. Fattener groups showed a lower frequency of positive animals compared to breeders, and in general, it was higher in technified farms (57.97 %) compared to semi-technified farms (45.1 %). Closed cycle farms showed a lower frequency of positive animals (48.2 %) compared to open and combined cycle farms. Pigs under semi-technified production conditions showed only 42.66 % of positive animals and there were differences depending on the farms of origin. These results may be associated both to the presence of unprotected animals due to vaccine failure at vaccination (33 ±3 days of age) in the presence of high maternal antibody titers, and to a high percentage of pre- or postnatally infected pigs that are immunotolerant and do not respond to the vaccine. These conditions favor CSF endemism in that territory and require the review of the strategies used to control the disease. An analysis of these results 10 years after this research was carried out is highlighted.
       
  • Expanded acute toxicity by intranasal administration of
           SURFACEN® in rats

    • Abstract: RESUMEN Los estudios de irritabilidad local para los productos inhalados constituyen un eslabón fundamental en la cadena de requisitos regulatorios de los estudios preclínicos toxicológicos, por este motivo el objetivo del trabajo fue determinar el potencial irritante de SURFACEN® en dosis repetidas por vía intranasal. Se utilizaron 30 ratas Cenp: Sprague Dawley (15 de cada sexo) distribuidas en dos grupos experimentales: control (solución de NaCl 0,9 %) y tratado (SURFACEN®). Ambos grupos recibieron el mismo esquema de tratamiento con dos aplicaciones diarias espaciadas entre sí, de cuatro a seis horas por vía intranasal, durante 14 días. La dosis a aplicar fue de 13,27 mg/kg. Las variables a evaluar fueron la observación clínica, el peso corporal, el peso corporal post mortem, el peso absoluto y relativo de los órganos seleccionados (pulmones, encéfalo) de cada animal y los estudios anatomopatológicos. El diseño y la conducción de la investigación se realizó según los principios de bienestar animal. Todos los animales sobrevivieron al estudio. No se evidenciaron diferencias estadísticamente significativas entre ambos grupos en las variables estudiadas. No hubo signos de toxicidad manifiestos tras la administración de SURFACEN® y no se detectaron alteraciones anatomopatológicas que pudieran estar asociadas a la administración del medicamento. Se evidenció que la aplicación de dosis repetidas por vía intranasal de SURFACEN® no alteró la morfología celular de la mucosa nasal, no causó daños histopatológicos en los órganos estudiados y no produjo signos de irritación local, por lo que se considera potencialmente no tóxico para humanos.ABSTRACT Local irritability studies for inhaled products constitute a fundamental link in the chain of regulatory requirements for preclinical toxicological studies. For this reason, the objective of the work was to determine the irritation potential of SURFACEN® in repeated doses by intranasal route. Thirty Cenp: Sprague Dawley rats (15/sex) were divided into two experimental groups: control (0.9 % NaCl solution) and treated (SURFACEN®). Both groups received the same treatment scheme with two daily intranasal applications spaced four to six hours apart, for 14 days. The dose to be applied was 13.27 mg/kg. Clinical observations, body weight, post mortem body weight, absolute and relative weight of the selected organs (lungs, brain) of each animal and pathological study were the variables to be studied. The design and implementation of the research was carried out according to the animal welfare principles. All animals survived the study. No statistically significant differences were evidenced between both groups regarding the variables studied. There were no signs of overt toxicity after SURFACEN® administration, and no anatomopathological alterations that could be associated with the administration of the drug were detected. It was evidenced that the application of repeated doses of SURFACEN® by intranasal route did not alter the cell morphology of the nasal mucosa, did not cause histopathological damage in the organs studied and did not produce signs of local irritation, thus it is considered potentially non-toxic for humans.

  • Detection of mutations involved in fluoroquinolone resistance in
           Mycoplasma gallisepticum positive field samples from broiler chicken
           flocks in Ecuador

    • Abstract: ABSTRACT The aim of this study was to determine the occurrence of mutations in the quinolone resistance-determining regions (QRDRs) of the genes gyrA and parC in M. gallisepticum positive field samples from broiler flocks in Ecuador. DNA was extracted from 24 M. gallisepticum PCR-positive samples from 22 commercial broiler flocks. The genes gyrA and parC were amplified by PCR. PCR products were sequenced by Sanger technology to analyze the genetic characteristics. To identify the mutations involved in fluoroquinolone resistance (FQR), the sequences obtained were processed and analyzed using the tools Geneious R11, BLASTn, MAFFT, ExPASy MBWS, and BioEdit. All samples had mutations in both gyrA and parC genes, resulting in changes at amino acid positions Ser-83→Ile and Ile-157→Val in GyrA, and Ser-80→Trp in ParC. In addition, a change at position His-59→Tyr in GyrA was also found in one sample. The results showed that alterations in both genes have been commonly linked to FQR in mutants of other Mycoplasma species, including M. gallisepticum. This is the first study on M. gallisepticum positive samples from chickens in Ecuador which revealed the occurrence of mutations resulting in amino acid changes previously linked to FQR.RESUMEN El objetivo de este estudio fue investigar la ocurrencia de mutaciones en las regiones determinantes de resistencia a quinolonas (QRDR de sus siglas en Inglés) de los genes gyrA y parC en muestras de campo positivas para M. gallisepticum, procedentes de parvadas de pollos de Ecuador. Se extrajo el ADN de 24 muestras positivas por PCR a M. gallisepticum de 22 parvadas de pollos de engorde de crianza comercial. Los genes gyrA y parC se amplificaron por PCR. Para analizar las características genéticas, los productos de PCR se secuenciaron por tecnología Sanger. Para identificar mutaciones involucradas en resistencia a fluoroquinolonas (FQR), las secuencias obtenidas se procesaron y analizaron utilizando las herramientas Geneious R11, BLASTn, MAFFT, ExPASy MBWS y BioEdit. Todas las muestras presentaron mutaciones, tanto en los genes gyrA como parC, lo que resultó en cambios en las posiciones de aminoácidos Ser-83→Ile e Ile-157→Val en GyrA, y Ser-80→Trp en ParC. Además, también se encontró en una muestra un cambio en la posición His-59→Tyr en GyrA. Los resultados mostraron que las alteraciones en ambos genes se han relacionado comúnmente con FQR en mutantes de otras especies de Mycoplasma, incluido M. gallisepticum. Este es el primer estudio en muestras positivas de M. gallisepticum de pollos en Ecuador que reveló la aparición de mutaciones que resultaron en cambios en aminoácidos, previamente vinculados a FQR.
       
  • Pediculectomy and left-sided hemilaminotomy in a canine with Hansen type I
           disc herniation between T13-L1 intervertebral levels

    • Abstract: RESUMEN A consulta llega Wiski, un canino mestizo de pequinés, macho de cuatro años de edad con paraplejia y signos de dolor espinal agudo. La conducta inicial fue atender la urgencia mediante terapia de fluidos, manejo del dolor y control de la presión sanguínea. El examen neurológico evidenció signos de motoneurona superior en los miembros pélvicos, compromiso en la propiocepción y en la función urinaria, dolor severo en la unión toracolumbar con una reducción del reflejo panicular. Los estudios imagenológicos (RX y TAC) confirmaron una Hernia discal Hansen tipo I entre la décimo tercera vértebra torácica y la primera lumbar. Se realizó un abordaje convencional para hemilaminectomía entre T13 y L1. Se realizó una primera pediculectomía exploratoria en el lado izquierdo del pedículo vertebral de L1, que evidenció material discal en la porción craneal, por lo que se inició una segunda pediculectomía en T13. Ambas pediculectomías se unieron mediante hemilaminectomía. Se retiró el material discal del canal vertebral y se realizó lavado del mismo con solución salina para terminar con la síntesis de los planos musculares, fascias toracolumbares, tejido subcutáneo y piel. El posoperatorio implicó la restricción total del movimiento, antibioterapia, terapia antinflamatoria y analgésica. La retención urinaria, asociada a los signos de motoneurona superior, se trató solo con Diazepan los primeros días. Durante los primeros 14 días, el paciente no presentó evidencias de dolor, sepsis o complicaciones quirúrgicas y, a los 23 días posoperatorios, el paciente recuperó la actividad motora de sus miembros pélvicos.ABSTRACT Wiski, a male mongrel dog (Pekingese breed) of four-year-old male, arrived for consultation. He presented paraplegia and signs of acute spinal pain. The initial protocol was to treat the emergency with fluid therapy, pain management and blood pressure control. Neurological examination revealed upper motor neuron signs in the pelvic limbs, compromised proprioception and urinary function, severe pain at the thoracolumbar junction with a reduced panniculus reflex. Imaging studies (X-ray and CT) confirmed a Hansen type I disc herniation between the thirteenth thoracic vertebra and the first lumbar vertebra. A conventional approach for hemilaminectomy was carried out between T13 and L1 intervertebral levels. A first exploratory pediculectomy was performed on the left side of L1 vertebral pedicle, which revealed disc material in the cranial portion; hence a second pediculectomy was started at T13. Both pediculectomies were joined by hemilaminectomy. Disc material was removed from the vertebral canal and washed with saline solution to finish the synthesis of the muscular planes, thoracolumbar fasciae, subcutaneous tissue, and skin. Postoperative period involved total restriction of movement, antibiotherapy and anti-inflammatory and analgesic therapy. Urinary retention, associated to upper motor neuron signs, was treated with Diazepam exclusively during the first days. During the first 14 days, the animal showed no evidence of pain, sepsis or surgical complications. At 23 postoperative days, the animal recovered the motor activity of its pelvic limbs.
       
  • Stability study of a prebiotic composed of fructans from Agave fourcroydes
           for its use as additive in livestock

    • Abstract: RESUMEN El objetivo de este trabajo fue desarrollar el estudio de estabilidad de vida útil, a temperatura ambiente, del prebiótico constituido por fructanos de Agave fourcroydes, para su utilización como aditivo en la ganadería. Se utilizó el método de vida de estante, por un periodo de 12 meses a temperatura ambiente. Se evaluaron las características físico-químicas al inicio, a los seis y 12 meses. Los resultados de estabilidad por vida de estante indicaron que el prebiótico mantuvo su estabilidad física por espacio de seis meses y la estabilidad química del principio activo durante los 12 meses. Se demostró que el prebiótico, constituido por fructanos de Agave fourcroydes, mantiene la estabilidad física del producto por espacio de seis meses y la estabilidad química del principio activo hasta los 12 meses, almacenado a temperatura ambiente.ABSTRACT The objective of this work was to develop the shelf life stability study, at room temperature, of the prebiotic composed of fructans from Agave fourcroydes, for its use as additive in livestock. Shelf life method was used for a period of 12 months at room temperature. The physical chemical characteristics were evaluated at baseline, six months and 12 months. Shelf-life stability results indicated that the prebiotic maintained its physical stability for six months and the chemical stability of the active ingredient for 12 months. It was demonstrated that the prebiotic, composed of fructans from Agave fourcroydes, kept the physical stability of the product for six months and the chemical stability of the active ingredient for up to 12 months, stored at room temperature.
