Indoor air contamination of the operating theatres is one of the major sources of life threatening nosocomial infections for patients undergoing certain surgical procedures. There is dearth of information on the burden of airborne microbial contaminations of operating theatres in this environment, hence the need for the study. The study aimed at investigating the airborne microbial load and type of pathogenic isolates as a result of surgical procedures in the operating theatres of a tertiary hospital in South-west Nigeria. A purposive selection of seven operating theatres was adopted for this study. Airborne microbial samples were collected using gravitational method and the total bacterial counts (TBC) and total fungal counts (TFC) per cubic-metre were determined before and after surgery. Indoor TBC and TFC after surgery (2.1x102 cfu/m3 and 0.17x102 cfu/m3) was significantly higher than before surgery (0.5x102 cfu/m3 and 0.03x102 cfu/m3) and the fisher's index. Staphylococcus spp. and Aspergillus spp. were one of the bacteria and fungi species isolated respectively. The study implicated the indoor environment of the operating theatres as a source of contamination.
