Seroprevalence and risk factors of Toxoplasma gondii infection in horses in Jilin Province and Inner Mongolia Autonomous Region, northern China.

This research outlines the prevalence and risk factors of the Toxoplasma gondii infection in horses in Northern China, specifically Jilin Province and Inner Mongolia Autonomous Region. The study could provide useful data for controlling and preventing toxoplasmosis in horses and other host organisms.

Overview of Research

• The study focuses on the evaluation of the seroprevalence— the level of pathogen-specific antibodies in the blood— of the Toxoplasma gondii (T. gondii) infection in horses. T. gondii is a protozoan parasite that can potentially infect all warm-blooded species. In this context, the study mainly pertains to the potential risk of toxoplasmosis—a disease caused by the infection of T. gondii—in horses slated for human consumption.
• A total of 614 serum samples were examined from horses in Jilin Province and Inner Mongolia Autonomous Region (IMAR) in Northern China collected between 2015 and 2017 to determine seroprevalence of T. gondii.

Findings

• The research found an overall seroprevalence of T. gondii in horses to be 17.92% (110 out of 614, as per the Indirect Hemagglutination Assay (IHA) test).
• It was noted that seroprevalence was lower in horses collected from Changchun (13.58%) compared to those from Meihekou City (21.72%) and Tongliao City (22.81%). This indicates a significant difference based on geographical location.
• Age of the horses was also a significant factor, with horses less than 12 months old showing higher T. gondii seroprevalence (22.75%) compared to horses aged 12 months or older (16.42%).

Significance

• This study is the first to report on the seroprevalence of T. gondii in horses in the mentioned regions of Northern China.
• The research identified age and geographical location of horses as significant risk factors for T. gondii infection, which could help in forming disease prevention strategies and control measures.
• Given that horse meat is a significant product for human consumption, the research’s findings could provide crucial insights for the safety and health hygiene of meat supply chains.
