ABSTRACT
The poultry industry plays a pivotal role in global food production, supplying a significant portion of protein-rich foods. However, bacterial infections in poultry pose substantial threats to both animal health and food safety. Antibacterial sensitivity testing, a critical tool in assessing antibiotic efficacy, is vital in poultry management. This project aims to investigate the antibacterial sensitivity of bacterial isolates recovered from various poultry sources. This research was carried out to isolate Gram negative bacteria presents in poultry droppings. Standard bacteriological methods were used to enumerate the total bacterial count. The bacterial isolates were characterized and identified using morphological and biochemical methods and sugar fermentation test. The percentage distribution and frequency of the isolates were evaluated using statistical method. In this study, five poultry farms were under study using their poultry droplets, the total heterotrophic bacterial count ranges from 13.63×1045.0 cfu/g to 20.0×10-15.00 cfu/g in penA samples and 21.6×1010.00 cfu/g to 22.7×1016.00 cfu/g in PenB samples. Using the standard cultural, morphological and biochemical test, the possible isolates obtained were, Klebsiella sp, Shigella sp, Citrobacter sp, Escherichia coli and Salmonella sp. The action of Escherichia coli, Salmonella and Shigella sp on hemolysin showed that they were pathogens of concern. The isolates were resistant multiple antibiotics namely colistin, erythromycin, tetracycline, methronidazole and clindamycin but were susceptible to a few antibiotics such as ciprofloxacin, gentamycin and augmentin. Conclusively, the present results provide evidence that poultry droppings can serve as an environmental reservoir of multiple enteric bacteria and hence as potential route for the entry of zoonotic pathogens into human population.
