MOQUILLO EN ZORRO COLORADO: La ocurrencia de moquillo en mamíferos silvestres refuerza la importancia de la vacunación periódica en cánidos domésticos a fin de conservar la salud de la fauna autóctona.

El moquillo canino es una enfermedad infectocontagiosa que afecta principalmente a perros, pero también a mamíferos silvestres. En 2022, se diagnosticó moquillo en un zorro colorado en Junín de los Andes, Neuquén. El aumento del número de perros con signos compatibles con esta enfermedad durante el 2021 nos pone en alerta por la posible transmisión del virus entre estas especies. La forma de prevenirla es la vacunación completa y anual, siendo una responsabilidad de todo ciudadano que posea perros bajo su cuidado, no solamente por el bien de los animales de compañía sino para el cuidado de la fauna silvestre en general

Post-mortem findings in southern right whales Eubalaena australis at Península Valdés, Argentina, 2003-2012

Between 2003 and 2012, 605 southern right whales (SRW; Eubalaena australis) were found dead along the shores of Península Valdés (PV), Argentina. These deaths included alarmingly high annual losses between 2007 and 2012, a peak number of deaths (116) in 2012, and a significant number of deaths across years in calves-of-the-year (544 of 605 [89.9%]; average = 60.4 yr-1). Post-mortem examination and pathogen testing were performed on 212 whales; 208 (98.1%) were calves-of-the-year and 48.0% of these were newborns or neonates. A known or probable cause of death was established in only a small number (6.6%) of cases. These included ship strike in a juvenile and blunt trauma or lacerations (n = 5), pneumonia (n = 4), myocarditis (n = 2), meningitis (n = 1), or myocarditis and meningitis (n = 1) in calves. Ante-mortem gull parasitism was the most common gross finding. It was associated with systemic disease in a single 1-2 mo old calf. Immunohistochemical labeling for canine distemper virus, Toxoplasma gondii and Brucella spp., and PCR for cetacean morbillivirus (CeMV), influenza A, and apicomplexan protozoa were negative on formalin-fixed, paraffin-embedded lung and brain samples from a subset of whales; PCR for Brucella spp. was positive in a newborn/neonate with pneumonia. Skin samples from whales with gull parasitism were PCR negative for CeMV, poxvirus, and papillomavirus. This is the first long-term study to investigate and summarize notable post-mortem findings in the PV SRW population. Consistent, significant findings within or between years to explain the majority of deaths and those in high-mortality years remain to be identifiedInst. de PatobiologíaFil: McAloose, DeniseWildlife Conservation Society Zoological Health Program; Estados Unidos.
