Keywords:Type of bacteria, Quantity of bacteria, Office
This study aimed to identify type and quantity of bacteria in the air collected from the administrative office of the Faculty of Science UdonThani Rajabhat University, Sam Phrao Campus. The study was conducted during May 2019 - April 2020 to cover all seasons in a year. The samples were collected -using Andersen N-6 stage sampler set at 75-120 cm. height from the ground (breathing zone) at flow rate of 28.3 l/minute for 10 minute. The results showed that. the highest average amount of total bacteria was found in the summer (234.39 CFU/m3) which comprised of 3 types of bacteria, namely Bacillus spp. 63.6% -Pseudomonas spp. 18%, and Staphylococcus spp. 18.4% respectively. The average amount of totel bacteria in rainy season was 233.21 CFU/m³ which comprised of -Pseudomonas spp. 23.7%, Staphylococcus spp. 76.3%. The lowest amount of total bacteria was found in the winter (186.09 CFU/m³) which comprised of 3 Bacillus spp. 60% Pseudomonas spp. 22.4%, and Staphylococcus spp. 17.6%. Our results revealed that the amount of bacterial found in all seasons did not exceeded the WHO standard of, 500 CFU/m³. The data analysis using F-Test by One-way ANOVA suggested that the amount of bacteria found among the 3 seasons, were not statistically significant difference (p>0.05)
