Abstract

BACKGROUND

Leptospirosis represents a One Health issue, affecting humans and animals. This study investigated pathogenic leptospires in small wild rodents in São Paulo, Brazil.

METHODS

Kidney samples from 164 rodents underwent qPCR testing, targeting pathogenic Leptospira spp.

RESULTS

Thirty-five animals (21.34%) tested positive, including five rodent species: Akodon montensis (2/21; 9.5%), Necromys lasiurus (1/4; 25%), Oligoryzomys nigripes (24/92; 26.1%), Oligoryzomys flavescens (5/26; 19.2%), and Sooretamys angouya (3/14; 21.4%). Botucatu municipality exhibited the highest prevalence, with 42.5% (20/47) of the animals testing positive.

CONCLUSIONS

The presence of Leptospira spp. in wild rodents suggests they may be chronic carriers, contaminating the environment.

摘要

背景

钩端螺旋体病是一个涉及人类和动物健康的问题。本研究调查了巴西圣保罗小型野生啮齿动物中的致病性钩端螺旋体。

方法

对 164 只啮齿动物的肾脏样本进行 qPCR 检测,以检测致病性 Leptospira spp。

结果

35 只动物(21.34%)检测呈阳性,包括 5 种啮齿动物:A. montensis(2/21;9.5%)、N. lasiurus(1/4;25%)、O. nigripes(24/92;26.1%)、O. flavescens(5/26;19.2%)和 S. angouya(3/14;21.4%)。博图卡图市的阳性率最高,47 只动物中有 20 只(42.5%)呈阳性。

结论

野生啮齿动物中存在 Leptospira spp. 表明它们可能是慢性携带者,污染了环境。
