E. coli infections in poultry are primarily caused by specific pathogenic strains, such as Enteropathogenic E. coli (EPEC) and Enterotoxigenic E. coli (ETEC). These strains can lead to various health complications in birds, including colibacillosis, a disease characterized by severe respiratory, urinary, and secondary systemic infections. Symptoms often include diarrhea, depression, and high mortality rates, particularly in young chicks. As poultry is a significant source of protein for humans globally, managing E. coli infections in birds is crucial for ensuring food safety and public health.
