Experimental infection of Friesian Holstein calves with an Indonesian isolate of Trypanosoma evansi.

ABSTRACT

The effect of a single, primary, artificial infection with Trypanosoma evansi was studied in nine Friesian Holstein calves. Body temperature, packed cell volume (PCV) and parasitaemia measurements were obtained daily from each of the infected calves for up to 90 days after parasites were injected, body weights were monitored weekly. T. evansi infection had a marked depressive effect on PCV profiles and the rate of body weight gain.
