Abstract
Bioaerosols play a significant role in indoor air quality as they can be the cause of severe health problems including acute allergies and infectious diseases. This study aimed to investigate the microbiological air quality assessment of University of Benin shuttle buses. Samples were collected from five different faculties using Nutrient agar and Potato Dextrose agar. The isolated bacteria and fungi were characterized by extensive phenotypic, cultural and biochemical identification procedures. The total bacterial count ranged from 10 cfu/m3 to 79 cfu/m3 and the bacteria isolated were Pseudomonas aeruginosa, Staphylococcus aureus, Micrococcus sp, Bacillus cereus, and Bacillus thuringiensis while the total fungal count ranged from 20 cfu/m3 to 57 cfu/m3 and the fungi isolated were Aspergillus sp, Penicillium sp, Fusarium sp, Cladosporium sp. Antibiotic susceptible pattern were carried out and the bacteria and fungi isolated were intermediate, sensitive or resistant to the antibiotics used. From the result obtained, the predominant isolated bacteria and fungi in the air sample of the shuttle buses were staphylococcus aureus, Bacillus cereus and Aspergillus sp respectively.
