airborne bacteria, bioaerosols, lecture rooms, sedimentation technique



This study was conducted to isolate and identify bacteria air pathogens in our college lecture rooms using the natural sedimentation technique. The studied areas include political science lecture room III, criminology and security study lecture room III, English lecture room III, environmental management and toxicology lecture room II, mathematics lecture room II, physics lecture room II, postgraduate lecture room and main hall science. A total of 64 samples were collected during the course of this study out of which 56 (87.5 %) showed positive bacterial growth. The isolated bacterial species were identified as Staphylococcus aureus, E. coli, Streptococcus species and Bacillus subtilis. Staphylococcus aureus had the highest percentage occurrence of 51% followed by E. coli (25%) and Streptococcus species (21%) while Bacillus subtilis recorded the least (3%). These pathogens could be linked with several infections such as gastrointestinal tract infections, respiratory tract infections, urinary tract infections and skin disorders. These findings would alert the students, staff and workers to these pathogens and their existence in our lecture rooms.
