Trypanosoma congolense: Calf erythrocyte survival

Experimental Parasitology, 1979
Abstract Hereford calves infected with Trypanosoma congolense developed an anemia which was most severe 10 weeks after infection when packed cell volumes (PCV) averaged 21.1 ± 2.5% (±2 SE) as compared to 33.1 ± 2.1% for controls. At the termination of the study, at 28 weeks postinfection PCVs of infected animals had risen to 27.5 ± 1.0% as compared ...

Trypanosoma congolense: Isolation and purification

Experimental Parasitology, 1979
Abstract Yields of Trypanosoma congolense grown in rats may be increased by placing the rats in a 37 °C environment for 1 hr prior to sacrifice. A further increase in the number of parasites recovered per rat may be achieved by replacement of blood removed by a lactated Ringer's solution with 5% glucose as the rat is being bled from the abdominal ...

Trypanosoma congolense infection in two dogs

Journal of Small Animal Practice, 1995
ABSTRACTTrypanosomiasis, caused by Trypanosoma congolense, was diagnosed for the first time in Israel in two boxer dogs imported from Kenya. The dogs developed clinical signs two days after arrival and succumbed to the disease within four days. The major clinical and clinicopathological findings included anaemia, haemorrhages, lymphadenomegaly ...

Nuclear DNA content of "Trypanosoma congolense"

Acta tropica, 1988
We have measured the nuclear DNA content of the major life cycle stages of Trypanosoma congolense, in two clones of geographically distant origin. We find that nuclear DNA content in epimastigote, mammalian blood-stream and metacyclic forms is constant and that the nuclear DNA contents of the two clones were 0.1 pg and 0.09 pg, respectively.

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. Currently

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.
