SUMMARY

Assessing microbial indoor air quality is one of the most important investigations for determining microbial indoor air pollution. Information on airborne microbial concentrations of bacteria and fungi is needed both to assess health risks and to establish standards for monitoring indoor air quality. (Wamedo et al., 2012). The concentration of bacteria and fungi aerosols in the indoor environment as sampled in this research work, carried out in medical laboratories of the University of Benin Teaching Hospital, estimated with the use of settle plate method ranged between 143-3693 CFU/m3 (colony forming unit per cubic metre) for bacteria isolated when there was much human activity (morning) and 47-2069 CFU/m3 for bacteria isolated when there was less human activity (afternoon). While for fungi isolates, 14-374 CFU/m3 isolated with much human activity (morning) and 14-531 CFU/m3 when there was less human activity (afternoon).
