ABSTRACT

The antibiotic susceptibility pattern of aerobic mesophilic bacteria isolated from kunu samples sold in Ile-lfe, Osun State, Nigeria was studied following standard microbiological methods. Seven ready-to-drink kunu samples were purchased from different hawkers at Ile Ife. The samples were transported immediately in ice bucket to the laboratory for analysis. The aerobic mesophilic bacteria associated with kunu samples were isolated, labeled and identified by phenotypic and biochemical tests. The antibiotic susceptibility pattern of the isolates against ceftazine, ceftazidine, cefuroxime, gentamicin, ceftriaxone, erythromycin, cloxlacillin, ofloxacin and amoxicillin, cefixime, augumentin and nitrofurantion was determined using the kirby-bauer disc diffusion method. The isolates identified include: Staphylococcus saprophyticus, Enterobacter intermidis, E. aerogenes, Bacillus sphaericus, Corynebacterium spp., Staphylococcus aureus, B. brevis, Citrobacter spp., Shigella spp. and Escherichia coli. The percentage occurence pattern of E. intermidis was 85.71 %, present in six out of the seven samples except Sample C while Staphylococcus saprophyticus and Shigella spp were 71.43%, present in five out of the seven samples, studied. E. coli has the least occurrence pattern with 14.29%. The Gram positive organisms were resistant to ceftazidime, cefuroxime, ceftriaxone and cloxacillin but susceptible to gentamicin, erythromycin, ofloxacin and amoxycillin. The Gram negative organisms were resistant to cefixime_, cefuroxime and augumentin but susceptible to gentamicin, nitrofurantion, ofloxacin and ciprofloxacin. The results obtained from this study indicated that kunu was contaminated by poor handling and lack of good manufacturing procedures. The microorganisms isolated from this study are of public health significance and their resistance to commonly used antibiotics such as ceftazidime, cefuroxime, ceftriaxone, augumentin and cloxacillin could constitute an alarming development with significant public health consequences.
