[ 4 ] - The efficacy of a poultry commercial anticoccidial vaccine in experimental challenge with Eimeria field isolates

BACKGROUND: The control of coccidiosis in poultry industryis dominated by prophylactic chemotherapy; however,drug resistance is a serious problem. Alternative control methodssuch as vaccination have been accepted as a practical method forcontrolling coccidiosis in chickens. Considering the immunologicalvariation of Eimeria strains, the efficacy of live coccidiosisvaccines may be compromised. OB...
