Abstract :
The present study demonstrated the prevalence of extended spectrum beta-lactamase (ESBL) -producing
enterobacteriaceae in liver samples of commercial broilers (commercial broilers) and backyard chickens (backyard
chickens). Results demonstrated that Escherichia coli (E. coli) was the most common isolate recovered from both commercial broilers (44.58%) and backyard chickens (57.03%), that followed by salmonella (commercial broilers: 35.06%;
backyard chickens: 21.09%), klebsiella (commercial broilers: 12.98%; backyard chickens: 13.28%), proteus (commercial broilers: 04.76%; backyard chickens: 06.25%), and enterobacter (commercial broilers: 02.59%; backyard chickens:
02.34%). The prevalence of E. coli and salmonella was found higher (P < 0.05) in commercial broilers as compared to
backyard chickens. However the prevalence differences of klebsiella between commercial broilers and backyard chickens were found statistically non-significant (P > 0.05). Among these isolates, 7.76% and 10.95% E. coli isolates were
recorded as ESBL -producing from commercial broilers and backyard chickens respectively. While 12.34% and 7.40%
salmonella isolates were found positive for ESBL production from commercial broilers and backyard chickens respectively. However, 13.33% klebsiella isolates of commercial broilers were declared as ESBL -producers; whereas klebsiella
isolates of backyard chickens and proteus and enterobacter of both commercial broilers and backyard chickens were
found negative for ESBL production. These results indicates that microbiota of commercial broilers established a
higher number of enterobacteriaceae as compared to backyard chickens, moreover, the prevalence of ESBL -producing
enterobacteriaceae in liver of commercial broilers was also higher than backyard chickens.
