Bacteriological analyses of Air samples from male hostels was carried out weekly for 4 weeks using standard microbiological methods in June, 2021 to determine their bacteriological content. Data obtained was analyzed using descriptive statistics and presented in tables. The result showed that the concentration of bacteria isolates increased as the duration of exposure of the media increased. The highest bacteria concentration was seen at room 205 at 40 minutes (29.8 x 10 2 CFU/M 3 ) and the least at room 204 at 20 minutes (0.9 x 10 1 CFU/M 3 ). The concentration of bacteria at other rooms were room 305 at 40 minutes (17.7 x 10 2 CFU/M 3 ), room 304 at 20 minutes had 1.3 x 10 1 CFU/M 3 , room 405 at 40 minutes had 17.8 x 10 2 CFU/M 3 , room 404 at 20 minutes had 3.6 x 10 1 CFU/M 3 , room 504 at 40 minutes had 17.6 x 10 2 CFU/M 3 and room 503 at 20 minutes had 11.9 x 10 2 CFU/M 3 . A total of eleven (11) different bacteria species were Original Research Article
