E. Coli in Poultry - Clinical Signs

Neonatal - Colibacillosis
Respiratory - colibacillosis and septicemia
Peritonitis

74

E. Coli in Poultry - Pathogenesis Neonatal

Yolk rest infection --> sepsis --> death
Yolk rest infection --> Polyserosistis/airsac/pericardia --> growth retardation
Contamination of egg shell
Neonatal contamination
Manipulation of chicks
