Seroprevalence of Toxoplasma gondii and Neospora spp. in horse population of Tehran, Iran.

Abstract: Neospora spp. and Toxoplasma gondii are two closely related protozoan parasites that are widely distributed throughout the world. Horses can act as intermediate hosts for both parasites and can acquire disease. Blood samples were taken from 487 clinically healthy horses from 17 different mechanized stables in Tehran, the capital of Iran, during September and November of 2022. IFAT and ELISA were employed to detect antibodies directed against Neospora spp. and T. gondii. The anti-N. caninum antibodies were detected in 52 of the horses (10.67%) based on IFAT and in 86 of the 487 horses (17.65%) based on the ELISA test. Also, antibodies against T. gondii were detected in 41 horses (8.42%) based on IFAT and in 63 of 487 horses (12.94%) based on the ELISA test. Also, in 6 of the horses (1.23%) based on IFAT and in 13 of the 487 horses (2.67%) based on the ELISA test, double positivity suggested co-infection with both parasites. Gender, age groups, and the presence of dogs for neosporosis, and age groups and the presence of cats for toxoplasmosis, could be considered factors having an influence on the seroprevalences (P < 0.05). The results proved the importance of the urgent implementation of stringent regulatory measures to prevent and control the spread of these parasites.

The given article studies the prevalence of two protozoan parasites, Neospora and Toxoplasma gondii, in the horse population of Tehran, Iran.

Introduction

  • The research falls into the realm of veterinary medicine and epidemiology, primarily focusing on the presence of two protozoans: Neospora spp. and Toxoplasma gondii in horses. These parasites are globally prevalent, with horses acting as potential intermediate hosts. The goal of the study is to quantify the prevalence of these parasites amongst the horse population in Tehran, Iran, and identify potential factors influencing their prevalence.

Methodology

  • The study was conducted by collecting blood samples from 487 clinically healthy horses from 17 mechanized stables in Tehran between September and November 2022. The samples were then tested for anti-Neospora spp. and anti-T. gondii antibodies using two common diagnostic techniques: Indirect Fluorescent Antibody Test (IFAT) and Enzyme-Linked Immunosorbent Assay (ELISA), both focused on identifying antibodies which the animal’s immune system would produce in response to the parasite infection.

Results

  • The findings showed that antibodies against Neospora spp. were present in 10.67% of horses (as per IFAT) and 17.65% of horses (as per ELISA). Meanwhile, the prevalence of T. gondii antibodies was lower, appearing in 8.42% of the horses (according to IFAT) and 12.94% of horses (according to ELISA).
  • Notably, both tests indicated the presence of dual infection in some horses, with IFAT and ELISA recording double positivity in 1.23% and 2.67% of the samples, respectively. This suggests co-infection with both parasites.
  • The study also observed certain factors that could influence the seroprevalence of these parasites. The gender and age of the horses, along with the presence of dogs, appeared to affect the prevalence of neosporosis, while the age of the horses and the presence of cats seemed to influence the prevalence of toxoplasmosis. These correlations were statistically significant at the P<0.05 level.

Conclusion

  • The findings emphasize the need for stringent regulatory measures to prevent and control the spread of Neospora spp. and T. gondii among horse populations to ensure their well-being and contribute to public health measures. In the presence of these influential factors, efforts should be directed towards reducing the risk of their spread.
