Characterisation and Antibiotic Testing of Clinical Bacteria Species Isolated from Kunu Drink Sold in Rumuolumeni, Nigeria

Abstract

The isolation, characterization and antibiotic sensitivity tests of some clinical bacteria species isolated from Kunu drink sold in Rumuolumeni, Rivers State was carried out. Samples of the Kunu drink was bought from vendors indifferent locations and their bacteriological counts enumerated using standard microbiological methods by the pour plate technique. The antibiotic sensitivity pattern of the pure bacteria isolates against some antibiotics was determined using the disc diffusion method. The total bacterial counts of the Kunu in the different locations ranged from4.0x102 to8.6x102cfu/ml. Four species of bacteria including Escherichia coli, Enterohacter aerogenes, Staphylococcus aureus and Streptococcus spp were isolated and identified by grain staining and their biochemical reactions. The most prevalent isolate in terms of occurrence was Escherichia coli (50%) followed by Enierobacter aerogenes (30%), Staphylococcus areus (10%) and Streptococctts spp (10%).
