Abstract

ABSTRACT: Leptospirosis is a zoonosis that can infect buffaloes and other mammalians, and it’s caused by Gram-negative bacteria of the genus Leptospira spp. The infection occurs through contact with urine or a contaminated environment with the mucous membranes of the animals, and the disease has two phases: leptospiremia and leptospiruria. The objective of this study was to determine the frequency of leptospirosis in buffaloes in the state of Paraná, Brazil, as well as the main serovars present in this area. A total of 276 blood samples were collected from buffaloes from 18 properties located in different cities and mesoregions of Paraná state. A microscopic agglutination test (MAT) was performed to detect the presence of anti-Leptospira spp. antibodies and to identify its serovars. The prevalence was 77.17% (213/276) of buffaloes seropositive for at least one serovar. The most frequent serovar was Icterohaemorrhagiae, followed by the Pomona serovar and serovar Hardjo. This study seems to be the first to determine the frequency of buffaloes with leptospirosis in the state of Paraná. Prevention and control measures are important to control the disease in herds.

巴西帕拉那州水牛钩端螺旋体的血清学频率

摘要:钩端螺旋体病是由革兰氏阴性菌钩端螺旋体引起的一种人畜共患病，可感染牛等哺乳类动物，通过接触动物的尿液或受污染的环境与动物的粘膜发生感染，该病可分为两期:钩端螺旋体血症和钩端螺旋体尿症。本研究的目的是确定巴西帕拉纳州水牛中钩端螺旋体病的频率，以及该地区存在的主要血清型。共采集了276份水牛血液样本，这些样本来自帕拉纳州不同城市和中部地区的18个地区。显微凝集试验(MAT)用于检测抗钩端螺旋体抗体的存在，并鉴定其血清型。阳性率77.17%(213/276)的水牛至少有一种血清型呈阳性。最常见的血清型是黄疸出血热，其次是Pomona血清型和Hardjo血清型。这项研究似乎是第一个确定帕拉纳州水牛患钩端螺旋体病频率的研究。预防和控制措施是控制畜群疫病的重要措施。
