 The African trypanosomes infect a broad range of mammals across sub-Saharan Africa and result in significant losses to domestic livestock. Subspecies of Trypanosoma brucei also cause African trypanosomiasis in humans resulting in approximately 20,000 cases per year.1 The development of vaccines against this disease is extremely difficult due to high antigenic variation of trypanosome surface glycoproteins, and a rise in resistance to trypanocidal drugs has been documented.2,3 Mouse models of infection and drug susceptibility are critical to understanding the mechanisms of disease and the development of new therapeutic drugs.
BEI Resources houses several isolates of T. brucei to support in vivo research on African trypanosomiasis. T. brucei subsp. gambiense, strain 348BT (NR-53513) is a recent acquisition that was isolated from a patient in the Democratic Republic of Congo before receiving treatment with melarsoprol that displays reduced sensitivity to the drug in laboratory mice.4,5
Other African trypanosome acquisitions in BEI Resources catalog include the reference T. brucei subsp. brucei, strain TREU 667 (NR-46440), as well as a variety of clinical isolates used in drug susceptibility studies in vivo.
