Coccidiosis research yielding new perspectives on AST

Adding molecular biology to anticoccidial sensitivity testing (AST) offers a more in-depth look — and surprising findings — of Eimeria species contributing to coccidiosis in poultry houses, explain Lorraine Fuller and Emily Kimminau from the University of Georgia.

E. acervulina, E. maxima and E. tenella had been thought to be the “big three” Eimeria species in US broiler houses. However, PCR is demonstrating that other species may be present, they report.
