Poul¬try industry, intensive farming practice and irrational use of medicated feeds in broiler and layer operations to improve feed efficiency has made poultry as a major reservoir of antimicrobial resistant strains of Salmonella and E. coli (Crump et al., 2002)
Foodborne diseases and poisoning in the contemporary world are emerging and great public health concerns. Foodborne infections are widely spread in both developed and developing countries. (Akbar et al., 2011)
Poultry is an important farm species in almost all countries, it can be raised with limited cap¬ital and is an important cheap source of animal protein, Birds are intensively reared for meat and egg purpose. (Okorie-kanu et al., 2016)
Escherichia coli and serovars of S. enterica. dominant members of Enterobacteriaceae, are responsible for major cause of foodborne infections worldwide. (Helmy et al., 2017).
Aetiology, History and Background Escherichia coli
Escherichia coli is a gram-negative facultative bacteria belongs to the family Enterobacteriaceae. It is ubiquitous, commensal in animals, strains of E.coli food- and waterborne zoonotic infection (Dhama et al., 2013).
Pathogenic strains of E.coli associated with diarrhea are Enterotoxigenic E. coli (ETEC), Enteopathogenic E. coli (EPEC), Enterohemorrhagic E. coli (EHEC) or Shiga toxin-producing E. coli (STEC), Enteroinvasive E. coli (EIEC), Enteroaggregative E. coli (EAEC) and Diffusely adherent E. coli (DAEC). Enteropathogenic E. coli and certain Enterotoxigenic E. coli strains of E. coli, are significant are the main cause of global health burden of diarrheal disease (croxen et al., 2013).
