| Abstract |
A quantitative and qualitative study of indoor air in two hospitals in Ekpoma, Edo State was carried out. Samples were collected using the settle plate method for the enumeration of bacterial and fungal isolates. This study is aimed at checking the microbial concentration of indoor air as it relates to hospital type, ward and sampling time. The total heterotrophic microbial population varied in the wards sampled from hospital to hospital. The bacterial population ranged from 18cfu/m3 to 288cfu/m3 in Faithdome hospital and 8cfu/m to 494cfu/m3 in Eromosele hospital. The fungal population ranged from 9cfu/m3 to 26cfu/m3 in Faithdome hospital and 3cfu/m3 to 45cfu/m3 in Eromosele hospital. The microbial floral isolated included six bacterial and six fungal genera among which are Staphylococcus aureus, Klebsiella spp, Streptococcus spp, Bacillus spp, Pseudomonas spp, Escherichia coli, Aspergillus spp, Penicillium spp, Candida spp, Trichophyton spp, Microsporium spp and Rhizopus spp. The degree of microbial distribution was highest in the waiting room and lowest in the theatre.
