Trypanosoma brucei (T. brucei) subsp. brucei, strain TREU 667 (Trypanosomiasis Research Edinburgh University) was originally isolated in Kenya.

The TREU 667 strain is a pleomorphic strain of low virulence to mice. It had been passaged once in rats after its receipt in Edinburgh, where it was established as a stabilate and kept in low temperature storage. T. brucei subsp. brucei, strain TREU 667 was obtained by Professor C. J. Bacchi from F. W. Jennings at University of Glasgow, United Kingdom. In mice, the TREU 667 strain produces a semi-acute infection lasting 60 to 70 days; this model of progressive pathology is more similar to natural infections in humans and domestic animals than acute models, which are lethal within a few days.

Each vial of NR-46440 contains approximately 0.5 mL of trypanosome infected blood with 20% glycerol, 6.25% Yaeger's anticoagulant and Trypanosome dilution buffer.
