Abstract

Background: The aim of the present study was to describe the presence of co-infection by Toxoplasma gondii and Neospora caninum in goats reared in extensive systems from Mexico. Materials and Methods: A cross-sectional study was conducted to determine the frequency of T. gondii and N. caninum, by detecting antibodies to each parasite by mean commercial ELISA kits. A total of 176 blood samples were randomly collected from mature females reared in extensive system herds from 20 municipalities of state of Guanajuato, Mexico. Results: The general seroprevalence was 23.9 and 21.0% for T. gondii and N. caninum, respectively, while co-infection rate was 3.6%. For geographic and environmental variables, no differences were observed among T. gondii and coinfection; however, it was observed that altitude, annual precipitation, annual average temperature, and rainy period showed significant differences with N. caninum seropositive goats. Conclusion: The seroprevalence of both parasites was appreciated in most of the studied herds. The present study is the first report of T. gondii and N. caninum co-infection in goats from extensive herds in Mexico.

墨西哥广域系统中饲养的山羊同时感染弓形虫和犬新孢子虫。

背景：本研究旨在描述在墨西哥广泛饲养系统中饲养的山羊是否同时感染弓形虫和犬新孢子虫。材料与方法：采用商业 ELISA 试剂盒检测两种寄生虫的抗体，从而确定弓形虫和犬新孢子虫的感染频率。研究人员从墨西哥瓜纳华托州 20 个城市的广泛饲养系统中饲养的成熟雌性牛群中随机采集了 176 份血液样本。结果显示淋病双球菌和犬双球菌的血清阳性率分别为 23.9% 和 21.0%，合并感染率为 3.6%。在地理和环境变量方面，没有观察到淋病双球菌和混合感染之间存在差异；但观察到海拔高度、年降水量、年平均气温和多雨期与 N. caninum 血清阳性山羊之间存在显著差异。结论在大多数研究的羊群中，这两种寄生虫的血清阳性率都很高。本研究首次报告了墨西哥广泛饲养的山羊同时感染淋病双球菌和犬疫双球菌的情况。

期刊介绍： Vector-Borne and Zoonotic Diseases is an authoritative, peer-reviewed journal providing basic and applied research on diseases transmitted to humans by invertebrate vectors or non-human vertebrates. The Journal examines geographic, seasonal, and other risk factors that influence the transmission, diagnosis, management, and prevention of this group of infectious diseases, and identifies global trends that have the potential to result in major epidemics. Vector-Borne and Zoonotic Diseases coverage includes: -Ecology -Entomology -Epidemiology -Infectious diseases -Microbiology -Parasitology -Pathology -Public health -Tropical medicine -Wildlife biology -Bacterial, rickettsial, viral, and parasitic zoonoses
