Trypanosoma evansi infection in worked and unworked buffaloes (Bubalus bubalis) in Indonesia

The effect of controlled amounts of exercise on the outcome of Trypanosoma evansi infection was studied in groups of swamp buffaloes (Bubalus bubalis) experimentally infected with T. evansi. Daily body temperature, packed cell volume (PCV) and parasitaemia measurements were obtained from each animal for up to 110 days after infection. Exercise did not appear to exacerbate the effect of T. evansi infection in that similar temperature, PCV and parasitaemia profiles were obtained with both exercised and rested animals. Trypanosoma evansi infection, however, had a marked effect on temperature and PCV profiles, both of which could adversely affect an infected animal's work output and work tolerance.
