aclear example of poultry disease hinder satisfying poultry production is collibacillosisThis is the localized or systemic infection caused by avian pathogenic Escherichia Coli (APEC). It manifests in diverse ways such as acute fata septicemia, subacute pericarditis, airsaculitis, salpingitis/ peritonitis, cellulitis and lymphocytic depletion of bursa and thymus.This infection is seen worldwide in chickens, turkeys, etc. Morbidity varies, mortality is 5-20%.

The infectious agent is moderately resistant in the environment, but is susceptible to disinfectants and to temperature of 80*c.ECONOMIC IMPORTANCE OF COLIBACCILOSISColibacillosis causes elevated morbidity and mortality leading to economic losses in the poultry farms especially around the peak of egg production, reduced FCR and carcass condemnation at processing in broilers.In LayersThere is sudden mortality with the absence of typical clinical signs due to the stress factors associated with egg production and systemically accompany by decrease in egg production and increase of poor-quality eggs.In BreedersWhen contamination of eggs with E. Coli lead to decrease hatchability and when there is in ovo contamination during incubation of eggs, this will also lead to production of poor-quality chicks with poor livability.In BroilersWhen there is systemic infection, this will lead to poor FCR (feed conversion ratio) and increased mortality, skin infection will cause inflammation of subcutaneous tissue which will lead increase condemnation of carcass at processing level.in 9 section I discuss the most important bacterial diseases affect poultrysection 1 introductionsection 2 how to investigate afield problemsection3 disease survailance necropsy - lab dignosissection4 chalamidiosis the most important zoonotic disease section5 infectious coryzasection6 salmonolosissection 7 fowl cholerasection8 mycoplasmosissection9 colibacillsis
