Leptospirosis is a bacterial zoonosis that affects both humans and animals worldwide. Currently, it is known that cats may be susceptible to infection. This study aims to investigate the presence of anti- spp. antibodies and leptospiruria in cats, using Microscopic Agglutination Test (MAT) and Real-time Polymerase Chain Reaction (PCR) techniques, respectively. A total of 76 cats, undergoing comprehensive anamnesis, general physical examination, and complementary exams were included in the investigation. Among the 76 cats tested, 9.2% (7/76) exhibited the presence of anti- spp. antibodies, while spp. DNA was detected in at 1.3% (1/76) of the evaluated urine samples. No significant associations were observed between the serological and molecular diagnostic results and the assessed variables, including clinical data and laboratory results of cats testing positive. This study provides insight into the occurrence of spp. infection and leptospiruria in cats treated at a veterinary teaching hospital in southern Brazil.

抗钩端螺旋体属的调查。巴西南部一家兽医教学医院的猫体内出现抗体和钩端螺旋体尿

钩端螺旋体病是一种影响全世界人类和动物的细菌性人畜共患病。目前，已知猫可能容易受到感染。本研究旨在调查抗 spp 的存在。分别使用显微凝集试验 (MAT) 和实时聚合酶链反应 (PCR) 技术检测猫体内的抗体和钩端螺旋体尿。共有76只猫接受了全面病历、一般体检和补充检查。在接受测试的 76 只猫中，9.2% (7/76) 表现出抗-spp. 的存在。抗体，而 spp。在所评估的尿液样本中检测到 DNA 的比例为 1.3% (1/76)。血清学和分子诊断结果与评估变量（包括检测呈阳性的猫的临床数据和实验室结果）之间没有观察到显着关联。这项研究提供了对 spp 的发生的深入了解。巴西南部一家兽医教学医院治疗的猫感染和钩端螺旋体尿。
