A stock solution of each of the samples was made by dissolving ten millilitre (10ml) of each sample in ninety millilitre (90ml) of sterile Tween 80. Six – fold serial dilution was made from each stock solution. Aliquots of the last two dilutions of each sample were inoculated on Plate Count agar (PCA) in duplicates using the pour plate method. All the plates were incubated at 35 0C for 24 hours. Colonies were counted after 24 hours and results expressed as colony forming units per millilitre.
