Abstract

Aims

Toxoplasmosis is one of the most common food-borne parasitic zoonosis, caused by Toxoplasma gondii, an obligate intracellular protozoan parasite. A cross-sectional study was carried out to determine the seroprevalence of T. gondii and associated risk factors in pigs in Haryana, India.

Methods and Results

Serum samples were collected from 429 pigs from three agroclimatic zones (I–III) of Haryana and analysed for the presence of antibodies against T. gondii using a commercial indirect enzyme-linked immunosorbent assay (ELISA). Anti-T. gondii antibodies were detected in 106 animals (24.7%), with the highest seropositivity in zone II (31.3%) followed by zone III (24.4%) and zone I (18.3%). Risk factors associated with higher seropositivity in pigs were farm size (higher in large-sized farms), age (higher in pigs >1 year of age), sex (higher in males), type of feeding (higher in combination of homemade and hotel waste) and housing (higher in free-ranging pigs).

Conclusions

The findings of the study testify to the exposure of pigs (of all agro-climatic zones) to T. gondii. Hence, the observations are of significant medical and veterinary importance for devising and implementing control measures to check the dissemination of toxoplasmosis to pigs and eventually to humans.

印度哈里亚纳邦猪弓形虫的血清流行率和相关危险因素。

目的：弓形虫病是由一种专性细胞内原生动物弓形虫引起的最常见的食源性寄生虫病之一。进行了一项横断面研究，以确定印度哈里亚纳邦猪的弓形虫血清流行率和相关风险因素。方法和结果：从哈里亚纳邦三个农业气候区（I-III）的429头猪身上采集血清样本，并使用商业间接酶联免疫吸附试验（ELISA）分析抗弓形虫抗体的存在。抗-T。在106只动物中检测到弓形虫抗体（24.7%），II区血清阳性率最高（31.3%），其次是III区（24.4%）和I区（18.3%）。与猪血清阳性率较高相关的风险因素是农场规模（大型农场较高）、年龄（>1岁的猪较高）年龄）、性别（雄性更高）、喂养类型（家庭和酒店垃圾的组合更高）和住房（自由放养的猪更高）。结论：研究结果证明（所有农业气候区的）猪都暴露于弓形虫。因此，这些观察结果对制定和实施控制措施以遏制弓形虫病传播给猪并最终传播给人类具有重要的医学和兽医意义。

期刊介绍： Zoonoses and Public Health brings together veterinary and human health researchers and policy-makers by providing a venue for publishing integrated and global approaches to zoonoses and public health. The Editors will consider papers that focus on timely collaborative and multi-disciplinary research in zoonoses and public health. This journal provides rapid publication of original papers, reviews, and potential discussion papers embracing this collaborative spirit. Papers should advance the scientific knowledge of the sources, transmission, prevention and control of zoonoses and be authored by scientists with expertise in areas such as microbiology, virology, parasitology and epidemiology. Articles that incorporate recent data into new methods, applications, or approaches (e.g. statistical modeling) which enhance public health are strongly encouraged.
