Antibiotics are emerging environmental contaminants, causing both short-term andlong-term alterations of natural microbial communities due to their high biological activities. The antibiotic resistance pattern of bacteria from anthropogenic polluted Oluwa River, Nigeria was carried out. Microbial profiling and antibiotic sensitivity tests were carried out on water andsediment samples using 13 different antibiotics. Microorganisms isolated include those in the generaBacillus, Micrococcus,Pseudomonas, Streptococcus, ProteusandStaphylococcus. The microbialcount of isolates from water samples ranged between 94.10·102Cfu/100 ml and156.20·102Cfu/100 ml while that of sediment samples ranged from 2.55·104Cfu g�1to14.30·104Cfu g�1. From the water isolates, 100% resistance to antibiotics was found inMicrococ-cusspp. andPseudomonasspp. while anotherMicrococcus, Streptococcus, StaphylococcusandBacillusspp. showed between 40% and 90% resistances. From the sediment isolates, 100%resistance to antibiotics was found in aBacillusspp. andPseudomonasspp. while anotherBacillus, Micrococcus, Staphylococcus, StreptococcusandProteusspp. showed between 70% and 90%resistances. Multiple antibiotic resistance (MAR) was shown by all the isolates and Bacillus, Micrococcus and Pseudomonasspp. showed the highest resistances (100%) to all antibiotics. Thus,Oluwa River is not safe for public consumption
