Abstract

The presence of selected pathogenic bacteria in biradon, kesham and kindrimo sold in Maiduguri, Nigeria was investigated. Results showed that the mean E. coli count was 2.43, 3.31 and 2.82 log 10 cfu mL -1, with range from 0.0 to 6.22, 0.0 to 6.30 and 0.0 to 5.48, respectively. Percentage E. coli in the samples was 21.6, 23.2 and 26.4%, respectively. The overall mean S. aureus count was 2.65, 1.16 and 2.41 log 10 cfu mL -1 and ranged from 0.0 to 6.79, 0.0 to 3.87 and 0.0 to 6.39, respectively with percentage distribution of 32.8, 19.6 and 18.6%, respectively. The overall mean Shigella count was 0.15, 0.40 and 0.24 log 10 cfu mL -1, respectively whereas, the range fell between 0.0 and 0.48, 0.0 and 2.48 and 0.0 and 0.90, respectively and percentage distribution was between 0.0 and 4, 2 and 10 and 2 and 8%, respectively. The overall mean Salmonella count was 1.44, 1.83 and 1.23 log 10 cfu mL -1, the range was between 0.0 and 4.02, 0.0 and 4.76 and 0.0 and 3.30, respectively and percentage distribution was 7.6, 9.8, 7.6%, respectively. Coliform overall mean of 2.94, 4.12 and 3.72 log 10 cfu mL -1, respectively was recorded and the range between 0.0 and 6.48, 0.0 and 7.51 and 0.0 and 6.70 and overall mean percentage coliform was 30.8, 38.6 and 35.2%, respectively. The total viable overall mean of 5.34, 7.27 and 6.58 log 10 cfu mL -1 and range value of between 0.0 and 8.48, 0.0 and 9.85 and 0.0 and 9.90, respectively was recorded.
