This study was conducted to learn the microbial diversity in our college environment so that we can we can develop a database of the microbial load and to have a preliminary idea of the environmental status. A total of 125 samples were collected in duplicate by open plate method from 5 different sites (Microbiology Laboratory, Classrooms, Toilets, Lift and Office rooms) at College of Applied Medical Sciences, Dawadmi was experimentally investigated during Months of October 2014 to February 2015. The number of Bacteria and fungi present in our college environment were studied by exposing Nutrient agar and Sabouraud Dextrose Agar plates for 30 minutes at different sites. The bacteria isolated were; Staphylococcus aureus, Coagulase –ve Staphylococcus, Micrococcus species and Bacillus species. The moulds isolated were Aspergillus fumigatus, Aspergillus niger, Alternaria species and Penicillium species. The yeast belonging to Rhodotorula species was also isolated. The data collected in this study can used for further research. Although microorganisms are present in our college, the amount is within the range (61 - 460 CFU/m3) which indicates a low level of contamination according to the guidelines by World Health Organization.
