Abdel-Rahman E. Elbasheir, El Ayis A. Abubaker* and Abdalla A. O. Abdelrahim
ABSTRACT In this investigation which lasted in 6 months of the year 2018, a total of 30 bacterial isolates were obtained from swabs of 30 fresh chickens’ carcasses. According to cultural characteristic and biochemical tests, the identified bacteria were 10 Staphylococcus spp. (33.3%), 9 Salmonella spp. (30.0%), 6 Escherichia coli (20.0%), 3 Klebsiella pneumoniae (10.0%) and 2 Listeria moncytogenes (6.7%). Staphylococci isolated were: 6 S. aureus (20.0%), 2 S. epidermidis (6.7%) and 2 S. xylosus (6.7%). Gram negative bacteria represented the predominant bacteria isolated from fresh chickens’ carcasses (60.0%), compared to gram positive bacteria (40.0%). In this investigation a total of 30 bacterial isolates were obtained from 26 frozen chickens’ carcasses’ swabs. The identified bacteria were: 10 Escherichia coli (38.4%), 10 Staphylococci (38.4%), 3 Salmonella spp. (11.5%), 7 Klebsiella pneumonia (7.8%) and 1 Listeria moncytogenes (3.8%). Staphylococci isolated were: 8 S. aureus (30.6%) and 2 S. epidermidis (7.8%). Gram negative bacteria represented the predominant bacteria isolated from frozen chickens’ carcasses (57.8%), compared to gram positive bacteria (42.2%). The study revealed that Chickens’ carcasses are more susceptible for contamination during processing than storage. Keywords: . [Download Article] [Download Certifiate] |
