This study aimed to verify Leptospira spp. serovar infections in stray dogs in Itapema, Santa Catarina, Brazil. Serum samples were collected from 590 stray dogs and tested against 25 Leptospira spp. serovars using the microscopic agglutination test. Prevalence of anti-leptospiral antibodies against one or more serovars was 10.5%. The most frequent serovar was pyrogenes, positive in 26 (18.0%) samples, followed by canicola with 20 (13.8%) and icterohaemorragiae and copenhageni with 18 (12.5%, with antibody titers from 1:100 to 1:3,200). Significant prevalence (10.4 to 11.1%) was also detected against serovars castellonis, butembo, and grippothyphosa.
本研究旨在验证巴西圣卡塔琳娜州伊塔佩马市流浪狗中钩端螺旋体属血清型感染情况。从590只流浪狗采集血清样本，使用显微镜凝集试验针对25种钩端螺旋体属血清型进行检测。针对一种或多种血清型的抗钩端螺旋体抗体阳性率为10.5%。最常见的血清型是致热型，26份（18.0%）样本呈阳性，其次是犬型，有20份（13.8%），黄疸出血型和哥本哈根型各有18份（12.5%，抗体效价为1:100至1:3200）。针对 Castellonis、Butembo 和 Grippothyphosa 血清型也检测到显著阳性率（10.4%至11.1%）。
