Animal trypanosomosis is one of the most severe constraints to agricultural development in sub-Saharan Africa and is also an important disease of livestock in Latin America and Asia. The causative agents are various species of protozoan parasites belonging to the genus Trypanosoma, among which T. congolense and T. evansi are the major pathogenic species. The extracellular position of trypanosom...

Resumo O macaco-prego (Sapajus nigritus) é um dos primatas que compõem a fauna silvestre do Rio Grande Sul. Assim como outros animais silvestres, os padecem de doenças infecciosas veiculadas por insetos, entre as quais, filarioses. Este relato apresenta aspectos anatomopatológicos uma infecção multissistêmica Dipetalonema spp. em macaco-prego, fêmea, adulta, origem silvestre, resgatado junto ro...

The study investigated the occurrence of trypanosomosis in water buffaloes using parasitological and molecular methods. Buffaloes of different ages and both sexes comprising Bulgarian Murrah and some crosses were used in the study. Two of the 145 samples (0.13%) were positive for Trypanosoma evansi in both, blood parasite examination and PCR. One female buffalo (1/54 samples; 1.86%) from a lact...

An histochemical and immunohistochemical study was carried out to evaluate the mechanisms of immune response of horses experimentally infected by Trypanosoma evansi. For this purpose the HE histochemical stain and the avidin biotin peroxidase method were used. To determine the presence and immunoreactivity of immune cells we used anti-major histocompatibility complex II antibodies. Cellular inf...

The tomato red spider mite, Tetranychus evansi, is an invasive pest reported on solanaceous crops in Benin around 2008, causing heavy economic damage. control of this mite by farmers mainly done through intensive applications chemical pesticides that are not always effective. In the present study, we evaluated a laboratory, at IITA-Benin, effects two botanical insecticides: Cashew Nut Shell Liq...

THE incrimination of the trypanosome as the cause of sleeping sickness and the discovery of the transmission of the parasite by the tsetse fly was the result of studies carried out in Uganda by Castellani, Bruce, Nabarro and others.' While there is no question of the importance of their elucidation of the relation between the disease, the parasite and the vector, by clinical, laboratory, and fi...

Plant quality for herbivores is usually evaluated with molecular and physiological techniques herbivore performance bioassays. These assays are done either on intact plants or detached plant parts, such as leaves, leaflets, leaf discs. It thus far unclear how experiments parts compare. may change in because of the mechanical wounding inflicted, which induce defences. Moreover, defences often sy...

background: although camels represent a valuable source of food, wool and hide in many countries, in-depth information about their vector-borne pathogens is scarce compared to other animals. the aim of the current study was to characterize vector-borne protozoa in the blood of dromedaries from iran by molecular tools. methods: from june to july 2014, 200 peripheral blood samples were collected ...
