Relationship between testicular lesion and hormone levels in male rats infected with Trypanosoma evansi.

Evaluation of Humoral Immune Response to Foot-and-Mouth Disease Vaccination in Experimentally Infected Guinea Pigs with Trypanosoma evansi

Testicular pathology, gonadal and epididymal sperm reserves of Yankasa rams infected with experimental Trypanosoma brucei brucei and Trypanosoma evansi

AIM The study was conducted to evaluate the pathological effects of trypanosomosis on the testes, gonadal, and epididymal sperm reserves of Yankasa rams for 98 days. MATERIALS AND METHODS A total of 16 Yankasa rams, aged between 24 and 30 months and weighed between 22 and 25 kg, were acclimatized for a period of 2-months in a clean fly proof house and were adequately fed and given water ad-li...

Specific antibody levels and antigenic recognition of Wistar rats inoculated with distinct isolates of Trypanosoma evansi.

"Mal de Cadeiras", an enzootic disease caused by Trypanosoma evansi, is one of the most important trypanosomiases in the Brazilian Pantanal region. The disease affects mainly horses, which are widely used in extensive cattle production, an activity of greatest economical significance for the region. The parasite also infects sylvan (coatis and capybaras) and domestic (dogs) animals, respectivel...

Oxidative Stress in the Heart of Rats Infected with Trypanosoma evansi

This study was conducted to investigate the occurrence of oxidative stress in the heart tissue of rats infected with Trypanosoma evansi. Rats were divided into 2 groups (A and B) with 12 animals each, and further subdivided into 4 subgroups (A1 and A2, 6 animals/each; and B1 and B2, 6 animals/each). Animals in the groups B1 and B2 were subcutaneously inoculated with T. evansi. Thiobarbituric ac...

A Preliminary Comparative Study on the Efficacy of Quinapyramine Sulphate/chloride and Melarsoprol in Rats, Experimentally Infected with Trypanosoma Evansi

Using standard parasitological, pathological, haematological and sero-biochemical methods, the trypanocidal effect of quinapyramine sulphate/chloride and melarsoprol has been compared in rats experimentally infected with Trypanosoma evansi isolated from a camel. The results indicated that infection in all rats resulted in fulminating parasitaemia (> 10 trypanosomes per mL). One week after treat...
