Endemic status of Trypanosoma evansi infection in a horse stable of eastern region of India–a field investigation.

Abstract: Diagnosis of Trypanosoma evansi infection in a horse stable of Eastern Region of India on the basis of examination of Giemsa stained blood smears have been done. A high percentage (12.74%) of horses of this stable was found suffering from T evansi infection. This high prevalence of T evansi in horses, in this area could be considered as an alarming situation which has never been explored previously in horses of Eastern Region of India. After a period of 2 months and 18 days of treatment with quinapyramine sulphate and quinapyramine chloride, reinfection with T evansi in treated horses of this stable were noticed. Clinical signs of affected horses and possible causes of reinfection have been discussed.

The research article focuses on diagnosing Trypanosoma evansi infection in horses in Eastern India by analyzing Giemsa stained blood smears, and discusses findings of a high prevalence rate and unnoticed reinfection post-treatment.

Introduction and Methodology

  • The study is centered on diagnosing Trypanosoma evansi infection in a horse stable in the eastern region of India.
  • Diagnosis was made by examining Giemsa stained blood smears from the horses.
  • Giemsa stain is a laboratory staining technique commonly used to visualize and identify the presence of parasites, such as Trypanosomes, in the blood.

Findings and Discussion

  • It was discovered that 12.74% of horses in the stable were suffering from T. evansi infection.
  • This high prevalence rate in this area was identified as alarming, especially because this issue had not been explored previously in horses in the Eastern Region of India.
  • After a period of two months and 18 days of treatment with quinapyramine sulphate and quinapyramine chloride, reinfection with T. evansi in the treated horses was observed. This brings to light the challenge of dealing with reinfection even after initial treatment.
  • The clinical symptoms of the infected horses and possible causes of reinfection were also discussed, suggesting the need for further research on this topic.

Conclusions and Implications

  • The study reveals an endemic status of T. evansi infection in horses in an eastern region of India, requiring urgent attention and intervention.
  • The observed reinfection after treatment indicates that there could be a need for more effective treatment methods or better after-care to prevent reinfection.
