ABSTRACT

The Antibiogram of Escherichia coli and Salmonella spp isolated from poultry intestinal fluid was investigated. A total of thirty (30) samples from poultry intestinal fluid were collected from different chicken (MOUAU farm and Isigate). The percentage occurrence of the isolates revealed Escherichia coli as being the most predominant isolate at 21(56.8%), followed by Salmonella species 16(43.3%).Antibiotic susceptibility and resistant profile for the isolates varied from isolate to isolate. The results of this study also showed that Escherichia coli was highly susceptible to Gentamycin (12.8%), Levofloxacin (12.8%), Streptomycin (12.8%) and Ampiclox (12.8%) and highly resistant to Chloramphenicol (35.5%). Salmonella species was highly susceptible to Ciprofloxacin (16.5%), Levofloxacin (16.5%), and Gentamycin (16.5%) and highly resistant to Chloramphenicol (40.0%). From the results of this study, we can deduce that there is necessity of performing antibiotic susceptibility test in hospital to profile the antibiotic susceptibility nature of each infectious organism for the correct treatment regimen. It is to report that Ciprofloxacin, Streptomycin, Gentamicin, and Ampiclox antibiotic could be of alternative of choice to use and to control Gram-Negative bacterial infection as an effective antibacterial agent.
