Abstract: Introduction Indoor environments are factors that do impact health. Air quality of indoor environments is a main factor affecting human health, well-being and productivity. A main problem of indoor air quality which people hardly pay attention to is the effect of the presence of diseases causing microorganisms. Methods: The indoor air microflora of 40 staff’s office in Elizade University was studied taking into consideration the number of occupants in the offices, gender, age, the number of windows, temperature, relative humidity and pressure, to know the microbial load and the type of organisms present. Isolation of microbes was done using the settle plate method, using Nutrient Agar (NA) for bacterial isolation and Sabouraud Dextrose Agar (SDA) for fungal isolation. The NA and SDA agar plates were incubated at 37 ° C for 24 hours for bacteria and 25 ° C for 3 days for fungi. Results: Bacterial counts ranged from 12 cfu/m 3 – Numerous and fungal counts ranged from 1 cfu/m 3 – Numerous. Bacterial isolates were purified from the nutrient agar and further identification of bacteria was done by coagulase test, catalase test and gram staining. While for fungal identification, lactophenol test was done. The CDC MicrobeNet was used to confirm the isolates. The bacteria identified found were Staphylococcus spp., Klebsiella spp., Micrococcus spp., Rhodotorula spp. and Streptococcus spp., while for fungi Fusarium spp., Aspergillus spp., Penicillium spp. and Rhodotorula spp. were identified. Conclusion: While it is generally known that indoor microorganism can be potentially a health hazard, there is no agreed upon level of airborne organism that signifies contamination for indoors and no health-based guidelines exist. In absence of guidelines it is recommended that more indoor study need to be done to understand the dynamics of airborne organisms in Nigeria from which health-based guidelines can be developed.
