DIFLUOROMETHYLORNITHINE FOR ARSENO-RESISTANT TRYPANOSOMA BRUCEI GAMBIENSE SLEEPING SICKNESS
Lancet, The, 198726 patients with arseno-resistant Trypanosoma brucei gambiense trypanosomiasis were treated with difluoromethylornithine (eflornithine), an inhibitor of ornithine decarboxylase, given intravenously, then orally. There was rapid disappearance of trypanosomes in the cerebrospinal fluid (CSF), gradual decrease of CSF lymphocytosis, and parallel ...

Aquaporin 2 Mutations in Trypanosoma brucei gambiense Field Isolates Correlate with Decreased Susceptibility to Pentamidine and Melarsoprol [PDF]
PLoS Neglected Tropical Diseases, 2013 The predominant mechanism of drug resistance in African trypanosomes is decreased drug uptake due to loss-of-function mutations in the genes for the transporters that mediate drug import. The role of transporters as determinants of drug susceptibility is

Mammalian immune responses to Trypanosoma brucei infection are important to control of the disease. In rats infected with T. brucei gambiense (Wellcome strain; WS) or T. brucei brucei (interleukin-tat 1.4 strain [ILS]), a marked increase in the number of macrophages in the spleen can be observed.

Restriction fragment length polymorphism (RFLP) has been analysed in Trypanosoma brucei DNA following hybridization with different DNA probes. This polymorphism seems to be due to allelic variation, and not to variation between sequence duplicates, since the genomic environment of the probed polymorphic fragments is conserved over considerable ...

Experimental Parasitology, 1992
Macrophages collected from BCG-infected mice or exposed in vitro to interferon-gamma plus lipopolysaccharide developed a cytostatic activity on Trypanosoma brucei gambiense and Trypanosoma brucei brucei. This trypanostatic activity of activated macrophages was inhibited by addition of N-monomethyl-L-arginine, an inhibitor of the L-arginine-nitric oxide

"Trypanosoma brucei gambiense" : cerebral immunopathology in mice
Acta tropica, 1982Ninety outbred white adult female mice were infected with Trypanosoma brucei gambiense (GUMS 2, alias LUMP 1237) originating from a Zairian patient and known to produce a low parasitaemia in rodents. The development of cerebral trypanosomiasis was independent upon the number of parasites inoculated per mouse.

Mechanism of Trypanosoma brucei gambiense resistance to human serum
Nature, 2013The African parasite Trypanosoma brucei gambiense accounts for 97% of human sleeping sickness cases. T. b. gambiense resists the specific human innate immunity acting against several other tsetse-fly-transmitted trypanosome species such as T. b. brucei, the causative agent of nagana disease in cattle.

Activity and kinetics of phospholipase A2 (PLA2) from Trypanosoma brucei gambiense (Wellcome strain) and Trypanosoma brucei brucei (GUTat 3.1) were examined using two different fluorescent substrates. The activity in the supernatants of sonicated parasites was Ca2+-independent, strongly stimulated by Triton X-100 with optimum activity at 37 degrees C ...

Immunological control of chronic "Trypanosoma brucei gambiense" in outbred rodents
Acta tropica, 1984Recent human isolates of Trypanosoma brucei gambiense generally fail to become or remain patent in laboratory rodents. The purpose of this study was to determine if this was due to acquired immunity and if so which immunosuppressive method was the most efficient in raising parasitemia levels.
