Prevalence of anti-Toxoplasma gondii antibody in domestic horses in Japan.

Abstract: The present study is the first report that investigated the seroprevalence of Toxoplasma gondii infection in domestic horses in various prefectures of Japan and analyzed risk factors for seropositivity. We performed a latex agglutination test for riding/racing horses from 11 prefectures in Japan (783 samples) and 4 groups of Japanese native horses (254 samples). The total seroprevalence of anti-T. gondii antibody in horses examined in this study was 4.24% (44/1037). As for riding/racing horses, we did not find a statistically different T. gondii seroprevalence between sampling prefectures. In contrast, seroprevalence of T. gondii in older horses (>21 years) was significantly higher than that in younger horses (<5 years and 11-15 years). There was no significant difference in T. gondii seroprevalence between riding/racing horses and Japanese native horses. Logistical regression analysis revealed that age, but not sex and usage, is a significant risk factor of T. gondii infection for domestic horses in Japan. These findings suggest that domesticated horses in Japan can be horizontally infected with T. gondii by ingestion of food or water contaminated with oocysts.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The article explores the existence of Toxoplasma gondii infection in domestic horses across different regions in Japan, and investigates the risk factors leading to higher susceptibility to the infection. It found that age was a significant determinant of risk, while horse usage and gender did not significantly influence infection rates.

Research Objective and Methodology

  • The researchers aimed to understand the prevalence and risk factors of Toxoplasma gondii infection in domestic horses in Japan.
  • They conducted a latex agglutination test on 783 riding/racing horses from 11 different prefectures and 254 Japanese native horses from four different groups.

Findings on Seroprevalence

  • The overall seroprevalence of anti-T. gondii antibody in the studied horses was 4.24% (44 out of 1037).
  • For riding/racing horses, there was no significant difference in T. gondii seroprevalence across different prefectures.
  • The seroprevalence in older horses (>21 years) was significantly higher compared to younger horses (<5 years and 11-15 years).
  • There was no significant difference in T. gondii seroprevalence between riding/racing horses and Japanese native horses.

Risk Factors for T. gondii Infection

  • Through logistical regression analysis, the study revealed that age was a significant risk factor for T. gondii infection in domestic horses in Japan.
  • However, there was no significant correlation between the risk of infection and the gender or usage of the horses.

Implications and Hypotheses

  • The findings suggest that domestic horses in Japan could be horizontally infected with T. gondii through the consumption of food or water contaminated with oocysts.
  • The infection is more likely to occur in older horses, indicating that there could be an age-related vulnerability to T. gondii.
