Antibiotic susceptibility patterns of microbial isolates from food and utilities in selected restaurants in Akoko communities of Ondo State, Nigeria

Abstract

The study shows the antibiotic resistance of microbial isolates encountered in foods, table surfaces, cleaning cloths and washing water at selected restaurants in some Akoko Communities, Nigeria. Food samples such as rice, beans, fufu, moin-moin, eba, amala and pounded yam were purchased from different restaurants at Oka, Ikare and Akungba-Akoko, Nigeria for microbiological analysis within 24 hours of collection. The antibiotic susceptibility profile of the isolates was determined in vitro using standard techniques. A total number of eighteen (18) bacteria and seventeen (17) fungal species were isolated from the samples. The bacterial species were identified as Aeromonas aerogenes, Aeroginosa spp, Bacillus cereus, Bacillus marscecens, Bacillus megaterium, Bacillus subtilis, Clostridium freundii, Clostridium sporogenes, Enterobacter cloacae, Micrococcus luteus, Klebsiella pneumoniae, Pseudomonas putida, Proteus vulgaris, Pseudomonas fluorescens, Staphylococcus aureus, Staphylococcus epidermis and Staphylococcus faecalis. The fungi isolates are Aspergillusa lutaceus Aspergillus Rhizomucur pusillus, Fusarium poae, Cunninghamella elegans, erythrocephalus, Gelasinospora retispora, Heteroconium chaetospira, Hormiactis candida, Penicillum fellutanum, Rhizopus oryzae, Torulaherbarum, Scopulariopsis brevicaulis, Syncephalastrum racemosun, Saccharomyces, Gliocladium viride, and Scopulariopsis brumptii. Most isolates obtained during the study showed multiple antibiotic resistance to Erythromycin (E) and Chloramphenicol (CH), Septrin (SXT), Zinnacef (Z), Gentamycin (CN) and Streptomycin (S). This study suggests the need to observe high level hygiene in eateries. Similarly, the nature of antibiotic resistance in this area can form a sort of database for health care management systems in case of infection from these sources
