Cinomose canina, Diagnóstico molecular, EpidemiologiaResumo
O vírus da cinomose canina (CDV) é uma infecção viral altamente contagiosa que causa imunossupressão e afeta cães domésticos e selvagens com alta mortalidade. Este estudo analisou retrospectivamente casos diagnosticados de CDV remetidos ao Laboratório de Diagnóstico Microbiológico da Faculdade de Veterinária da Universidad de la República (Montevidéu, Uruguai) entre 2021 e 2023. Foram processadas 251 amostras, principalmente de Montevidéu (85 %), com CDV detectado em 119 por meio de RT-qPCR. Não houve diferenças significativas por sexo, e os cães menores de 2 anos foram mais suscetíveis (71,4 %). Sessenta por cento dos casos não estavam vacinados, enquanto 28 % tinham um plano de vacinação completo, sugerindo possíveis falhas vacinais. Os cães mestiços foram os mais afetados, mas o CDV foi detectado em várias raças. Os sinais principais foram neurológicos, seguidos por respiratórios, digestivos e dermatológicos; 24 % apresentaram sinais combinados. A análise filogenética sugere uma linhagem predominante de CDV no Uruguai, com algumas cepas divergentes. Compreender a epidemiologia e a apresentação clínica do CDV no Uruguai é fundamental para melhorar as estratégias de prevenção, diagnóstico e tratamento.
