Effect of isometamidium on Trypanosoma congolense infectivity

Veterinary Parasitology, 1991
Isometamidium chloride (Samorin, RMB, England) is a widely used and highly effective trypanocide for the treatment of bovine trypanosomiases. However, the appearance of isometamidium-resistant populations of T. congolense in Africa makes it necessary to develop methods for the rapid and reliable detection of drug resistance in the laboratory.

Expression of foreign proteins in Trypanosoma congolense

Molecular and Biochemical Parasitology, 1999
An expression vector was constructed to express foreign genes in Trypanosoma congolense. The foreign gene and a neomycin phosphotransferase (NPT) gene are flanked by glutamate and alanine rich protein (GARP) gene processing signals and their expression is driven by a ribosomal RNA gene promoter.

Trypanosoma congolense: Thrombocyte survival in infected steers

Experimental Parasitology, 1982
Abstract Charolais steers infected with Trypanosoma congolense developed a thrombocytopenia that was first demonstrated shortly before the onset of parasitemia. The thrombocyte count progressively decreased from a level of 6 × 105/mm3 on the 3rd day postinfection to l × 105/mm3, its most depressed level, on the 11th day postinfection. The mean of the

Trypanosoma congolense: Thrombocytopenia in experimentally infected cattle

Experimental Parasitology, 1978
Abstract Hereford cattle infected with Trypanosoma congolense developed a thrombocytopenia which was most severe early in the course of infection when parasite levels in peripheral blood were highest. As the disease progressed, parasite levels gradually decreased and a corresponding increase in the number of thrombocytes occurred.

Trypanosoma congolense: Infectivity for white mice

Experimental Parasitology, 1968
Abstract White mice of Swiss strain are susceptible to Trypanosoma congolense. Intact, splenectomized, irradiated, or irradiated and splenectomized mice showed no variation in susceptibility to infection. The incubation period varied from 4 to 19 days.

Multiplication of Trypanosoma brucei and Trypanosoma congolense in vertebrate hosts

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1969
Abstract Studies on multiplication of T. brucei and T. congolense showed that trypanosomes artificially maintained in mice multiply exclusively by longitudinal fission. T. brucei and T. congolense in a rabbit and a guinea-pig as well as in sheep has, in addition to multiplication by binary fission, a developmental cycle which includes ...

Congenital transmission of Trypanosoma congolense in mice

Journal of Comparative Pathology, 1983
Pregnant mice were infected with a strain of T. congolense which produces a chronic infection, to determine if congenital infection can occur. Some of the mice were killed before delivery and tissues of foetuses injected into clean male mice. Other mothers were allowed to deliver and the tissues of some of the 1-day-old young inoculated into male mice ...

Sequential infection of tsetse flies with Trypanosoma congolense and Trypanosoma brucei

Acta Tropica, 1992
The question whether tsetse flies can be experimentally infected with more than one trypanosome species or strain by sequential feeding was investigated using DNA probe technology to identify directly the small numbers of trypanosomes in the fly gut. Bloodstream form trypanosomes of Trypanosoma congolense or T. brucei ssp.

Kinetoplast DNA from Trypanosoma vivax and T. congolense

Molecular and Biochemical Parasitology, 1985
We have analysed kinetoplast DNA (kDNA) of the African trypanosomes Trypanosoma vivax and T. congolense. The maxi-circles from these organisms resemble those of T. brucei in size, but only to a limited extent in sequence as judged from restriction enzyme digests and DNA X DNA hybridization. The kDNA networks of T.
