Capilariose urinária em gato doméstico (Felis catus): relato de caso

Abstract

Urinary capillariosis, caused by nematodes of the genus Capillaria spp., represents an infection that affects the urinary tract of felines, leading to clinical alterations such as dysuria, hematuria, cystitis, and painful sensitivity upon abdominal palpation. In Brazil, reports of this disease in domestic cats (Felis catus) remain scarce, consisting predominantly of isolated case notifications. The objective of this study was to report a case of urinary capillariosis in a domiciled, neutered male cat treated at a private veterinary clinic in João Pessoa, Paraíba. The diagnosis was confirmed by the identification of bioperculated eggs compatible with Capillaria spp. in the urinary sediment obtained by cystocentesis, along with the absence of bacterial growth in urine culture. The animal presented recurrent episodes of cystitis and, following confirmatory diagnosis, was treated with fenbendazole combined with topical application of imidacloprid and moxidectin, resulting in a satisfactory clinical response. This report reinforces the importance of urinary sediment examination as a routine diagnostic tool for urinary disorders in domestic felids and highlights the need for broader epidemiological studies aimed at understanding the distribution, risk factors, and therapeutic efficacy concerning urinary capillariosis in urban feline populations.
