Objetivo. Determinar la presencia de anticuerpos a B. canis en perros domésticos y callejeros del municipio de Villavicencio, Colombia. Materiales y métodos. Se utilizó la prueba de aglutinación rápida en placa con antígeno menos mucoide (M-) en 201 muestras de suero. En dos animales seropositivos se realizó intento de aislamiento por hemocultivo en medio selectivo para Brucella (oxoid®). En un animal seropositivo, con crecimiento bacteriano con características morfológicas sugestivas a B. canis se realizó histopatología de testículo, bazo e hígado. Resultados. La seropositividad general fue de 1.49% y correspondió a tres caninos machos, dos de los cuales presentaron signos clínicos de epididimitis y orquitis (unilateral). El cultivo y la histopatología no fueron concluyentes para el diagnostico de B. canis. Conclusiones. La seropositividad fue baja y sugiere que la población estudiada no ha estado en contacto con la bacteria. La presencia de reactores puede estar asociado con falsos positivos. El no aislamiento de la bacteria no indica que la enfermedad no exista por lo que se requiere de nuevos estudios.
The pustulose ark, Anadara tuberculosa, is considered as an emblematic species of the east Pacific mangrove ecosystem. The decline of its populations is of increasing preoccupation, in particular in Peru. The use of hatchery-produced larvae for stock enhancement or aquaculture is attractive but raises strong criticisms from an ecological point of view, as it could conduce to loss of genetic diversity in wild populations and favor the disease spreading from hatcheries to the environment. In this works, spat production through traditional aquaculture/biotechnology technologies was associated with pathogen molecular diagnostics and with genetic diversity estimation to produce specific pathogen-free (SPF) larvae from genetically characterized populations. All PCR and nested-PCR diagnostics of common bivalve pathogens, such as Bonamia, Martelia, Perkinsus and OsHV1, led to negative results for healthy or moribund adults and spat samples. Microbiological and molecular analyses realized during mortalities led to identifying a pathogenic Pseudomonas strain present on culture tank walls, in moribund spats and adults´ blood. Population genetic variation was assessed by mitochondrial COI gene sequences which showed 36.7% haplotype diversity. This study with hatchery production, pathology and genetic components for an overexploited native bivalve represents an original model for successful mollusk stock enhancement or/and innovative aquaculture programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
