Capillaria spp. infections of the urinary tract of domestic carnivores are uncommon worldwide. Infections are rarely diagnosed and are typically asymptomatic. This study aimed to evaluate a case of capillariosis in a cat from the state of Rio de Janeiro, Brazil. A seven-year-old female cat with apathy and reduced appetite was presented. Urine analysis revealed C. plica eggs in urine sediment, and cystitis was evidenced by the presence of bacteria, pyuria, proteinuria and hematuria. The subject was treated with 50 mg/kg fenbendazole for five days. Urine samples were frozen for molecular analysis and species confirmation. Polymerase chain reaction for amplification of the 18S rRNA gene followed by sequencing confirmed the occurrence of Capillaria sp. There has been limited phylogenetic study of Capillaria spp. in cats, so further studies are needed to identify the species present in different locations and associated with feline pathogenesis.
犬猫尿路毛细线虫感染在世界范围内较为少见。感染通常不易诊断且多为无症状。本研究旨在评估巴西里约热内卢州一只猫的毛细线虫感染病例。一只七岁雌性猫表现出精神沉郁和食欲不振。尿液分析显示尿液沉渣中有 C. plica 卵，且存在细菌、脓尿、蛋白尿和血尿提示膀胱炎。该病例接受了 50 mg/kg 芬苯达唑治疗五天。尿液样本被冷冻用于分子分析和种属确认。18S rRNA 基因的聚合酶链反应（PCR）扩增和测序证实了毛细线虫属的存在。目前对猫源毛细线虫种属的系统发育研究有限，因此需要进一步研究以确定不同地区与猫发病机制相关的种属。
