Abstract

ABSTRACT Leptospirosis and toxoplasmosis are zoonoses of occupational character that are spread worldwide, mainly in tropical and socioeconomically vulnerable areas. Both diseases have vertebrate hosts, which spread the infectious agent to the environment and are potentially infectious to humans and can progress to fatal cases. The present study reinforces the importance of One Health for the control and prophylaxis of leptospirosis and toxoplasmosis using sentinel animals in areas of socioeconomic vulnerability based on a serological study. A total of 336 blood samples were obtained from the canine population of the urban district, which has high rates of poverty and sanitation. The results were analyzed based on seroreactivity animals and georeferencing by kernel spatial mapping. A total of 43.3% (52/120) of the animals were seroreagents for anti-Leptospira spp., with a predominance of Canicola (35/52 = 67.3%) and Pyrogenes (5/52 = 9.6%), while 52.97% (178/336) of the dogs were seroreactive for anti-Toxoplasma gondii. The presence of seroreagent dogs for both zoonosis alert to the inadequate hygienic-sanitary conditions of the studied region, and highlight the importance of a survey of the social, economic and environmental structure to identify factors related to the links in the epidemiological chain of pathogen transmission and necessary corrective actions.

社会经济和环境脆弱地区犬群钩端螺旋体病和弓形虫病血清患病率的空间分析

钩端螺旋体病和弓形虫病是一种具有职业特征的人畜共患疾病，在全球范围内传播，主要分布在热带和社会经济脆弱地区。这两种疾病都有脊椎动物宿主，它们将传染源传播到环境中，对人类具有潜在传染性，并可能发展为致命病例。基于血清学研究，本研究强调了One Health在社会经济脆弱地区使用哨点动物控制和预防钩端螺旋体病和弓形虫病方面的重要性。共从贫困率和卫生条件较高的城市地区的犬类种群中采集了336份血液样本。基于血清反应性动物和核空间映射的地理参考对结果进行分析。共有43.3%（52/120）的动物是抗钩端螺旋体的血清试剂。其中以犬（35/52=67.3%）和Pyrogenes（5/52=9.6%）为主，52.97%（178/336）的狗对弓形虫有血清反应。两种人畜共患病的血清试剂犬的存在提醒人们注意研究地区卫生卫生条件不足，并强调了对社会、经济和环境结构进行调查的重要性，以确定与病原体传播的流行病学链中的环节相关的因素和必要的纠正措施。
