website builder Infectious bronchitis is a never-ending battle for poultry producers, but its the secondary infection E. coli that often proves to be the most costly to broilers in terms of condemnations and mortality. Kalen Cookson, DVM, director of clinical research at Zoetis, talks with Poultry Health Today about his experiences with the pathogen in US broiler flocks.

Consistent surveillance and analysis of infectious bronchitis virus (IBV) at poultry production facilities can guard against “overvaccination” — where too much vaccine virus in the environment causes a rolling reaction in flocks.
E.coli may be largely responsible for focal duodenel necrosis (FDN) in layer chickens, according to research presented at the 2022 International Poultry Scientific Forum (IPSF).
A higher risk of bacterial challenges in cage-free egg production means a live-vaccination program against Escherichia coli is a “must-have minimum” for flocks reared in alternative systems.
