Isolation of phage-antibodies against Eimeria species that infect chickens.

Eimeria is one of the most economically important pathogens in poultry production. Diagnosis of infection has the potential to inform treatment and prevention strategies. Here, phage display technology was used to isolate single chain antibodies (scFvs) that had a broad specificity against oocysts from the seven pathogenic species of Eimeria found in poultry.
