Prevalence of antibodies to Encephalitozoon cuniculi in horses from Brazil.

Abstract: Encephalitozoon cuniculi has been associated with natural cases of abortion and stillbirth in horses. However, little is known about the prevalence of this parasite in horses. We examined sera from 559 horses from Brazil for antibodies to E. cuniculi using the indirect immunofluorescent antibody (IFA) test and the direct agglutination test (DAT). We found that 79 (14.1%) were positive in the IFA test and 70 (12.5%) were positive in the DAT. Compared to the IFA as the "gold standard" the sensitivity of the DAG was 94.0% and the specificity was 96.1%. Our study indicates that horses in Brazil are frequently exposed to E. cuniculi.

The research article is about a study conducted to determine the prevalence of antibodies to the pathogen Encephalitozoon cuniculi in horses from Brazil, which has been linked to cases of abortion and stillbirth in horses. The findings indicate that a significant proportion of the horses were exposed to this pathogen.

Research Objective and Methodology

  • The primary goal of this research was to ascertain the prevalence of the pathogen Encephalitozoon cuniculi among horses in Brazil. This parasite has reportedly been associated with incidents of abortion and stillbirth in equines but there isn’t sufficient prevalence data available.
  • The researchers examined serum samples collected from 559 horses in Brazil. The presence of antibodies to E. cuniculi in these samples was assessed using two tests – the Indirect Immunofluorescent Antibody (IFA) test and Direct Agglutination Test (DAT).

Key Findings

  • Out of 559 horse serum samples, 79, representing 14.1%, were found to be positive for antibodies to E. cuniculi using the IFA test. Similarly, 70 horse serum samples, or 12.5%, tested positive with the DAT method.
  • When using the IFA test results as a “gold standard”, the DAT method demonstrated a sensitivity of 94.0% and a specificity of 96.1%. This indicates that the DAT method is a highly effective procedure for detecting antibodies to E. cuniculi in horse serum samples, as it accurately identified most positive (sensitivity) and negative (specificity) cases when compared to the IFA test results.
  • The researchers concluded that E. cuniculi exposure is fairly common in horses in Brazil, based on the considerable percentage of horses that tested positive for antibodies to this parasite.

Implication of the Study

  • This research provides valuable data on the prevalence of Encephalitozoon cuniculi among horses in Brazil. This information is crucial for devising effective disease management strategies and preventative measures.
  • The findings also validate the effectiveness of the DAT method for identifying antibodies to E. cuniculi in horse serum samples, raising the potential for broad-scale testing and monitoring for this parasite.
