Abstract

Leptospira reactivity in stray and household dogs in Campeche as well as associated risk factors to the seropositivity in household dogs have been herein determined. The survey included 323 dogs, 142 of which were stray dogs and 181 household dogs. Nine Leptospira interrogans serovars were tested by the microagglutination test. Reactivity was 21.3 % (69/323), 17.2 % corresponded to household dogs and 26.7 % to stray dogs. Leptospira Canicola (29 %), Leptospira Hardjo (22.58 %), and Leptospira Icterohaemorrhagiae (16.12 %) were the most common serovars reacting against the serum of household animals, while Leptospira Canicola (15.78 %), Leptospira icterohaemorrhagiae (13.15 %), and Leptospira Pomona (7.89 %) were those reacting in stray dogs. Results showed that all dogs have been in contact with different Leptospira serovars and outdoor exposure is the main infection risk factor.

摘要

本文已确定坎佩切州流浪狗和家犬的钩端螺旋体反应性以及家犬血清阳性的相关风险因素。该调查包括323只狗，其中142只为流浪狗，181只为家犬。通过微量凝集试验检测了九种问号钩端螺旋体血清型。反应性为21.3%（69/323），家犬的反应性为17.2%，流浪狗的反应性为26.7%。犬型钩端螺旋体（29%）、哈焦型钩端螺旋体（22.58%）和出血性黄疸型钩端螺旋体（16.12%）是与家畜血清反应最常见的血清型，而犬型钩端螺旋体（15.78%）、出血性黄疸型钩端螺旋体（13.15%）和波摩那型钩端螺旋体（7.89%）是在流浪狗中出现反应的血清型。结果表明，所有狗都曾接触过不同的钩端螺旋体血清型，户外暴露是主要的感染风险因素。
