[Serological survey of animal toxoplasmosis in Senegal].

Abstract: Toxoplasma gondii is an obligate, intracellular, parasitic protozoan within the phylum Apicomplexa that causes toxoplasmosis in mammalian hosts (including humans) and birds. We used modified direct agglutination test for the screening of the animals' sera collected in Senegal. In total, 419 animals' sera have been studied: 103 bovines, 43 sheep, 52 goats, 63 horses, 13 donkeys and 145 dogs. The collection of sera was performed in four different regions of Senegal: Dakar, Sine Saloum, Kedougou and Basse Casamance from 2011 to 2013. We have revealed antibodies in 13% of bovines, 16% of sheep, 15% of goats, 30% of horses, 23% of donkeys and 67% of dogs. Private dogs from villages were more often to have the anti-Toxoplasma antibodies compared to security society-owned dogs from Dakar. It may be explained by different meal consumed by dogs (factory-produced meal for dogs from Dakar vs. irregular sources for village dogs). Intense circulation of T. gondii in the studied zone may explain the unusually high seroprevalence among horses and donkeys. Tropical climate with high temperature and humidity is favorable for the conservation of oocysts of T. gondii. Results presented here may contribute to the evaluation of the risks of toxoplasmosis in humans in Senegal.

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.

This research studies the presence of Toxoplasma gondii, a parasite that causes toxoplasmosis, in various animal species in Senegal. The findings suggest a considerable prevalence of the parasite, particularly among dogs, horses and donkeys, indicating potential human risk in the area.

Research Methodology

  • The research used a modified direct agglutination test to screen for toxoplasmosis in animals’ blood serum.
  • In total, samples from 419 animals across a range of species were studied. This included bovines, sheep, goats, horses, donkeys and dogs.
  • The collection of samples occurred in four distinct regions of Senegal — Dakar, Sine Saloum, Kedougou and Basse Casamance — between 2011 and 2013.

Key Findings

  • The results identified antibodies for T. gondii, indicative of toxoplasmosis infection, in a significant number of animals of each species: 13% of bovines, 16% of sheep, 15% of goats, 30% of horses, 23% of donkeys and 67% of dogs.
  • The research singled out dogs from villages as having a higher likelihood of carrying anti-Toxoplasma antibodies compared to security society-owned dogs from the city of Dakar. The researchers suggest that this discrepancy may be due to the differences in dietary habits between these groups.
  • The high prevalence of T. gondii antibodies in horses and donkeys in the region could indicate intense circulation of the parasite, with the tropical climate possibly facilitating the survival of T. gondii oocysts, the infective stages of the parasite.

Implications of the Research

  • The study provides valuable data on the prevalence of toxoplasmosis in domestic and farm animals in Senegal.
  • This information could be instrumental in helping to assess human risk for toxoplasmosis in the area, considering the parasite can also infect humans.
  • Understanding the risk factors, such as the dietary habits of animals, can aid in creating preventative measures to reduce the incidence of the disease.
