A study on indoor airborne bacteriological contamination in various laboratories of Science Laboratory Technology in Ramat Polytechnic Maiduguri, Borno state, is presented. The present study is aimed at determination of indoor-air bacteriological contamination of SLT laboratories. Investigations were conducted in March, 2016. Air samples were taken twice a day: in the morning (10am) and in the afternoon (4pm). Total numbers of mesophilic aerobic bacteria count (ranged between 1.0 x 102 - 5.3 x 102 cfu/m3) from the air of selected laboratories were determined using Koch sedimentation method. This was determined through sampling using “Settled Plate Technique (SPT)”, Petri plates filled with nutrient agar was used in the sample collection. In all of the tested places a multiple growth of bacteria were observed in afternoons than in the morning hours. The predominant bacteria isolated from investigated air samples were: Escherichia coli 24(41.37%), Klebsellia pneumonia 7(12.07), Shigella spp 9 (15.52), and Staphylococcus spp 18 (31.03). Among these bacterial isolates the presence of pathogenic and strongly allergenic microorganisms was detected. The current study clearly indicates that there is significant assessment of the indoor airborne bacteria.


Keywords: Indoor air, bacteriological quality, airborne bacteria, open plate technique.
