Cytauxzoon spp. são piroplasmas hemoparasitos que parasitam espécimes da família Felidae. A cytauxzoonose é uma enfermidade caracterizada principalmente por sinais clínicos inespecíficos e súbitos. Tem como reservatórios os felídeos silvestres, no entanto já existem relatos de parasitemia crônica em felinos domésticos. A transmissão ocorre principalmente por vetores como carrapatos na América do Norte; já na América do Sul, Europa e Ásia os vetores são ainda desconhecidos. A patogenia decorre da fase de esquizogonia do parasito em macrófagos que causa obstrução de vasos sanguíneos. O tratamento é baseado nos cuidados de suporte e a combinação terapêutica de atovaquona associada à azitromicina tem demonstrando bons resultados. A profilaxia consiste na restrição do acesso de gatos domésticos em áreas arborizadas que possuam a presença de carrapatos e no uso de repelentes-acaricidas. Com esta revisão de literatura, objetivou-se analisar os aspectos epidemiológicos, clínicos e patológicos que permitam subsidiar o médico veterinário atuar com rapidez em casos suspeitos de cytauxzoonose.Downloads
