| Canine trypanosomiasis, caused by protozoans of the genus Trypanosoma, is divided into two primary types: the American form (Chagas disease), due to Trypanosoma cruzi infection, and the African form (sleeping sickness or surra), provoked by Trypanosomaevansi. This disease was originally enzootic and affected only wild animals, including mammals and birds, which served as reservoirs. Later, it spread to domestic animals such as horses, cattle and dogs. The disease became a zoonosis when contact between rural inhabitants and natural Trypanosoma foci occurred, due to ecological imbalances and increasing migration. Dogs are significantly involved in this context, because they are the main domestic animals and participate in the transmission and maintenance... |

| The morphometric characteristics of three Venezuelan isolates of Trypanosoma evansi, and the basic hematological features as well as host’s body weight were registered throughout experimental murine infections. The phenomena, trypomastigote morphometry dynamics, mouse hematological change and mice body variation, are related in statistical terms. In addition, the changeable morphometric characteristics of the hemoflagellate, and the host’s mutable hematological attributes, and the variable host’s body eight produced three different mathematical models generated by Multiple Linear Regressions that could explain the heterogeneous behavior of this eclectic parasite. Even more, supplementary mathematical models provided by Correspondence Analysis emphasize... |

| Background: This study was conducted in response to recurring reports from eastern Sudan of camel trypanosomosis that can no longer be treated by currently available trypanocidal drugs. One hundred and eighty-nine blood samples were obtained from camels in different herds and local markets in the western part of Sudan, and a cross-sectional study was carried out between December 2015 and February 2016 to identify the causative agents and possible circulating genotypes. Results: The prevalence of trypanosomes detected using the conventional parasitological techniques of Giemsa-stained blood smears, wet blood smears and the microhematocrit centrifugation technique (MHCT) was 7% (13/189), 11% (21/189) and 19% (36/189), respectively. However, a multi-species... |

| The susceptibility of BALB/c, C57Bl/6, DBA/2, NMRI, NIH and CD1 mouse strains to experimental infection with a Venezuelan equine isolate of Trypanosoma evansi was examined through hemoglobin concentration, packed red cell volume, number of erythrocytes per blood μl, parasitemia, body weight, and mice survival time. The said variables seem to be suitable markers to contrast the mouse susceptibility to T. evansi experimental infections. Among the evaluated mouse strains, NMRI was the more susceptible and DBA/2 the less vulnerable to the local T. evansi isolate used in the study. The resistant mouse strains could help in the identification of factors conferring natural resistance against T. evansi, while the susceptible could be used to investigate the... |

| Trypanosoma evansi from buffalo, cattle and horse isolates were purified by Diethylaminoethyl cellulose column chromatography. The purified trypanosomes from each sources were used separately for preparation of whole cell lysate antigens. A comparative study on polypeptide pattern of whole cell lysate antigens of these three isolates of T. evansi was studied. It showed a total of 11 dominant polypeptide bands with relative molecular weight ranging from 95 to 13 kDa, when resolved in 10% sodium dodecyl sulphate polyacrylamide gel electrophoresis and stained with Coomassie brilliant blue. Except some minor differences between the relative molecular weight of isolates in a particular region, the polypeptide profiles of these three isolates did not resolve any... |

| Babesia bovis, B. bigemina, Trypanosoma evansi, and Anaplasma marginate infections cause serious diseases in cattle, and are primarily transmitted by arthropod vectors (ticks for B. bovis, B. bigemina, and A. marginate and various types of flies for T. evansi). In the last few years, there have been many reports of a high prevalence of certain protozoan infections in northern Egypt, but no accurate or adequate data are available for the southern regions. Therefore, in this study, we screened for evidence of such diseases in economically important cattle species using serum samples. The seroprevalence of protozoan infections in cattle was determined with enzyme-linked immunosorbent assays using species-specific diagnostic antigens. In a total of 301 cattle... |

| Camel trypanosomosis (Surra) is one of the most important diseases affecting camel calves. It presents itself as an acute form and is usually fatal if treatment is not carried out. A study was initiated at Mogwooni ranch in Laikipia district of Kenya to survey the prevalence of trypanosomosis in camel calves of mixed breeds, and to evaluate the microhaematocrit centrifugation technique (MHCT), monoclonal antibody based card latex agglutination test (Suratex®), wet smear and mouse inoculation (MI) in the diagnosis of the disease in camels. The tests were assessed for a period of 16 months. The mean Trypanosoma evansi prevalence ranged from 4.5% as determined by the wet smear, 11.1% by MHCT, 14.6% by MI, to 28.3% by Suratex®. Young calf death rate due to... |
