Infecção por morbillivirus canino em onça parda (Puma concolor) no estado de Mato Grosso, Brasil : relato de caso

Abstract

Infections of non-domestic felids with domestic carnivore viruses are reported worldwide. Canine Morbillivirus (CDV) can determine several clinical and pathological changes in domestic dogs and wild animals. Wild felids are susceptible to CDV and when infected can develop neurological, respiratory and gastrointestinal signs. The pressure of agriculture, industry and urbanization has fragmented the habitat of brown jaguars (Puma concolor) in Brazil making it an endangered species. Even in suitable environments, these cats face a variety of threats, such as poaching the species and its prey. Declines in wild feline populations caused by infectious diseases have been reported and the CDV morbidity and mortality rates seen in felids can vary. Based on the absence of data on the occurrence of this virus in brown jaguars in Mato Grosso, this study reports a natural infection by CDV in two brown jaguars in the municipality of Cuiabá diagnosed using RT-PCR and electron microscopy. The animals were hospitalized and showed clinical signs of aspiration bronchopneumonia, which after established treatment showed improvement and clinical cure.
