ABSTRACT
Poultry dropping is a complete nuisance especially in this modern age where there is concern with pollution of the environment. Pathogenic microorganisms can thrive in poultry wastes. These constitute environmental and health hazards to livestock and the teeming population. The presence of these microorganisms cause various diseases. 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 13.63X106±50 cfu/g to 20.0X106±15.00 cfu/g in penA samples and 21.6X106±10.00 cfu/g to 22.7X106±16.00cfu/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. This have important implications for human health, as infections are difficult to treat and often requires expensive antibiotics and long term therapy.
