Effec of corticosteriod administration on the infectivity of Tyypansome brucei (8/18) in the Nigerian domestic chickens (Gallus Gallus Domesticus)

This study was aimed at determining how the infectivity of trypansome brucei could be affected by steriod administration to the local chickens. It has been shown that Nigeria domestic chickens were susceptible to Trypanosome brucei (8/18), In the course of this study the Try some brucei brucei (8/18) was found to have lost Its infectivity  to the local chickens. Even steroid administration at both low (0.2mg/ml) and high (1.0inglinl) dosage and prolonged administration of the steroid could not change this occurrence. The study thus concluded that serial passage of T brucei brucei (8/18) over a time will make it loose infectivity to Nigerian domestic chickens (Gallus gallus domesticus).
