Antibiotic resistant pattern of isolated bacteria from Obere River in Orile-Igbon, Oyo State, Nigeria

Good quality water must be odourless, colourless, tasteless and free from pathogens. This is adversely affected when it is polluted beyond certain limits. Potable water for domestic use should however be free of pathogenic organisms. Water samples were collected from Obere River in Orile-lgbon, Oyo state, Nigeria in order to study the antibiotic resistance pattern of isolated bacteria. The bacteria genera detected were Pseudomonas, Bacillus, Proteus and Flavobacterium. The isolates were subjected to antibiotic sensitivity test with about 90% showing multiple antibiotic resistance. All the isolates have a high resistance rate (100%) against amoxicillin, augmentin (100%), streptomycin (95%), chloramphenicol (95%) and ceftriaxone (90%); while, the least resisted antibiotics was ciprofloxacin (35%). It was concluded that Obere River in Orile-Igbon, Oyo State is polluted with pathogenic bacteria showing multiple antibiotic resistance. Thus, there is need for proper treatment of water in this study area before distribution for consumption and general domestic usage.   Key words: Water samples, Obere River, antibiotic sensitivity test, multiple antibiotic resistance.
