Outbreak of trypanosomosis due to Trypanosoma evansi in horses of Pantanal Mato-grossense, Brazil.

Abstract: This paper reports an outbreak of trypanosomosis due to Trypanosoma evansi in horses of the Pantanal Mato-grossense region of Brazil. Forty-eight horses died (51% mortality) and abortion in one mare was recorded. The clinical signs observed were fever, anemia, conjunctivitis, edema of the legs and lower parts of the body, progressive weakness, loss of condition, and loss of appetite. The diagnosis was confirmed by morphological and biometrical studies.

This research investigates an outbreak of the disease trypanosomosis in horses in Brazil’s Pantanal Mato-grossense region, caused by the Trypanosoma evansi parasite, resulting in significant mortality and symptoms like fever, anemia, and loss of appetite.

Background

  • The research focuses on an outbreak of a disease in horses known as trypanosomosis, caused by a parasite named Trypanosoma evansi. This outbreak occurred in the Pantanal Mato-grossense region of Brazil. Trypanosoma evansi is a common parasite affecting horses and other animals, leading to multiple health complications. The outbreak resulted in a significant death rate among these animals with 48 horses reported dead, which accounts for a 51% mortality rate among the observed network.

Symptoms

  • Horses infected by this parasite displayed familiar clinical signs indicative of trypanosomosis. These symptoms included fever, anemia, conjunctivitis, edema of the legs and the lower body parts, increasing weakness, and a gradual deterioration of condition.
  • Unusually, loss of appetite was also observed among the infected horses, which generally does not form part of the standard symptom profile of trypanosomosis in horses. In addition, one mare was reported to have undergone abortion, suggesting an adverse effect on reproductive health as well.

Methodology

  • The research utilized morphological and biometrical studies to confirm the diagnosis of trypanosomosis among the infected horses. Morphological studies could involve observing the shapes and forms of the parasites within the horses, while biometrical studies may include various measurements allowing more precise diagnosis.
  • Such methodology ensures that the observed symptoms and resultant health problems are indeed because of the presence of Trypanosoma evansi and the subsequent trypanosomosis they cause, rather than any other potential health issue.
