A survey was conducted to determine the prevalence of T. evansi in domestic animals in Rayalaseema region of Andhra Pradesh during the year 2009-10. A total of 1166 blood and sera samples from cattle, buffaloes and sheep were collected and screened by Wet blood film examination and Indirect ELISA. Overall, 1.54 and 24.52 per cent animals were found positive for T. evansi by Wet blood film (WBF)...

Trypanosoma evansi and Trypanosoma vivax, which are the major causative agents of animal trypanosomosis in Venezuela, have shown a very high immunological cross-reactivity. Since the production of T. vivax antigens is a limiting factor as this parasite is difficult to propagate in experimental animal models, our goal has been to identify and isolate antigens from T. evansi that cross-react with...

Surra is an animal pathogenic protozoan infection, caused by Trypanosoma evansi, that develops into a fatal wasting disease. Control measures rely on diagnosis and treatment. However, with the continuous emergence of drug resistance, this tactic is failing, and the pressing need for new chemotherapeutic agents is becoming critical. With the introduction of novel aromatic diamidines, a new categ...

In a recent study dealing with a mouse model of Trypanosoma evansi-associated disease, a remarkable synchrony between the parasitaemia peak and the white-blood-cell count nadir was noticed. The present study was designed to establish whether there is a direct causal link between the parasite load during its exponential phase of growth and the disappearance of peripheral blood leukocytes. In vit...

Three objectives have been achieved by the Working Group since its creation in 1983: more detailed information (and consequently better awareness) of zones infected by T. evansi; refinement of diagnostic techniques and the development of test kits suitable for field use; development of a new synthetic trypanocide. Exchange of strains between specialist laboratories should be encouraged in order...

This study aimed to characterize astrocytic and microglial response in the central nervous system (CNS) of equines experimentally infected with T. evansi. The experimental group comprised males and females with various degrees of crossbreeding, ages between four and seven years. The animals were inoculated intravenously with 10(6) trypomastigotes of T. evansi originally isolated from a naturall...

"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...

BACKGROUND Trypanosoma evansi infections, commonly called 'surra', cause significant economic losses to livestock industry. While this infection is mainly restricted to large animals such as camels, donkeys and equines, recent reports indicate their ability to infect humans. There are no World Animal Health Organization (WAHO) prescribed diagnostic tests or vaccines available against this disea...

Trypanosomiasis is an important protozoan disease of domestic animals and man. One the pathogenic trypanosomes in Trypanosoma evansi; causative agent Surra that highly fatal to a number domesticated mammals such as camels. Mentha longifolia plant has been used traditional medicine treat some parasitic microbial diseases different countries. This study was conducted evaluate antitrypanosomal act...

Dipetalonema (Alafilaria) hydrochoerus subgen. et sp. n. is described from specimens recovered from skeletal muscle fascia of the capybara, Hydrochoerus hydrochacris, from several localities in Colombia, South America. The microfilaria, which is found in the skin of the host, is also described for the first time. The monotypic species of the subgenus Alafilaria can be distinguished from existin...
