Drug resistance in Sudanese Trypanosoma evansi

Veterinary Parasitology, 1999
The drug sensitivities of 16 Trypanosoma evansi isolates from Sudan were examined using two different in vitro assays and rodent models. IC50 values (concentration which inhibited incorporation of 3H-hypoxanthine by 50%) obtained in a 40 h assay indicate that most of the isolates were resistant to suramin, a drug which has not been used in Sudan since ...

Trypanosoma evansi in capybara from Venezuela

Journal of Wildlife Diseases, 1997
During the slaughtering season of February and March 1991, 559 capybaras (Hydrochoerus hydrochaeris) were tested for Trypanosoma evansi in two areas in Venezuela: El Frio Ranch and El Cedral Ranch. Blood and serum samples were evaluated for T. evansi. Forty-eight (9%) of 559 capybaras had T. evansi using the microcentrifugation technique. Further, 279 (

Enzootiology of Trypanosoma evansi in Pantanal, Brazil

Veterinary Parasitology, 2004
In order to better understand the enzootiology of trypanosomiasis caused by Trypanosoma evansi in the Brazilian Pantanal we examined domestic and wild mammals by microhematocrit centrifuge technique (MHCT), immunofluorescence antibody test (IFAT) and polymerase chain reaction (PCR). T. evansi infection was detected in all species sampled with exception

Identification of the surface components of Trypanosoma evansi

Research in Veterinary Science, 1992
125I-labelling was used to characterise the surface components of five stocks of Trypanosoma evansi. Two components of 67 and 60.5 kD were labelled in two of the stocks, a single 60.5 kD component in two other stocks and no components in the remaining stock.

Pathogenic mechanisms of Trypanosoma evansi infections

Research in Veterinary Science, 2012
Insect-borne diseases exact a high public health burden and have a devastating impact on livestock and agriculture. To date, control has proved to be exceedingly difficult. One such disease that has plagued sub-Saharan Africa is caused by the protozoan African trypanosomes (Trypanosoma species) and transmitted by tsetse flies (Diptera: Glossinidae ...

Drug sensitivity of Chinese Trypanosoma evansi and Trypanosoma equiperdum isolates

Veterinary Parasitology, 1994
The drug sensitivities of eleven Trypanosoma evansi isolates from China were examined using two different in vitro assays, a 3H-hypoxanthine incorporation assay and a long incubation low inoculation test (LILIT). Better discrimination of the drug susceptibility of the strains was observed with the LILIT.

A Biochemical and Immunological Comparative Study on Trypanosoma equiperdum and Trypanosoma evansi

Veterinary Research Communications, 2003
Trypanosoma equiperdum and Trypanosoma evansi were purified by three or four cycles of low-speed centrifugation and final filtration through DEAE cellulose. The purified trypanosomes were used in comparative biochemical and immunological studies. Comparative polypeptide pattern analysis revealed that T.

Biochemical detection of adenosine deaminase in Trypanosoma evansi

Experimental Parasitology, 2011
Biochemical and molecular research on parasites has increased considerably in trypanosomes in the recent years. Many of them have the purpose of identify areas, proteins and structures of the parasite which are vulnerable and could be used in therapy against the protozoan.

Cytokines in rats experimentally infected with Trypanosoma evansi

Experimental Parasitology, 2011
The aim of this study was to measure the levels of interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), interleukin 1 (IL-1) and interleukin 6 (IL-6) in the serum of rats experimentally infected with Trypanosoma evansi and to correlate these levels with hematological parameters.

The distribution of nucleic acids in Trypanosoma evansi

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1961
Abstract 1. 1) Feulgen's nucleal reaction, pyronin staining and fluorescence microscopy with acridine orange were used to investigate the distribution of nucleic acids in a normal and an akinetoplastic strain of Trypanosoma evansi . 2. 2) Deoxyribonucleic acid was found in the nuclear periphery of both strains and in the kinetoplast ...
