Attenuated strains in coccidiosis vaccines

With the currently increasing problems of drug-resistance and pressures from consumers to ban drugs from animal feeds, there is a pressing need to move away from chemotherapeutic control of coccidiosis towards vaccination.

Most commercially available coccidiosis vaccines contain live oocysts of non-attenuated or attenuated strains of different Eimeria species, with the attenuated commercial vaccines produced using different attenuation methods.

HIPRAhave produced a video that explains the process of attenuation of vaccine strains by precociousness. It is part of a detailed article on the attenuation process and the efficacy of attenuated vaccines against coccidiosis. Access the full article here.

As the world’s poultry production continues to grow, so do concerns about the control of Eimeria infections that cause coccidiosis, which remains one of the most commonly reported diseases of chickens. Hipra have produced a resouce library on Eimeria prevention to support the industry.
