Description
Summary:Antibiotic-resistant bacteria (ARB) strains have become a global health threat. This study aimed to determine the antibiotic susceptibility pattern of Klebsiella pneumoniae and Pseudomonas aeruginosa isolated from wells in Ondo town, Southwest Nigeria. Twenty-eight well water samples were analyzed for the presence of K. pneumoniae and P. aeruginosa by standard pour plate technique. The bacterial isolates were tested against eight commonly use antibiotics using Kirby Bauer disc diffusion method. The percentage occurrence of K. pneumoniae and P. aeruginosa in the well water samples were 17.86% and 21.43%, respectively. Two multi-drug resistant strains of K. pneumoniae were isolated, which were resistant to at least three classes of antibiotics. Fifty percent of the P. aeruginosa isolates were resistant to caftazidime, cefuroxime, nitrofurantoin, and ampicillin. None of the isolates was fully susceptible to cefuroxime, but have all showed resistance to β-lactam (ceftazidime, cefuroxime augmentin, and ampicillin) antibiotics. Cefuroxime may not be effective an effective drug in the treatment of K. pneumoniae and P. aeruginosa implicated infections in these communities in Ondo. Also, the over-use of antibiotics should be discouraged in order to curtail the menace of antibiotic resistance.
