the results showed that there was a logarithmic relation
between total bacterial counts and the number of genera
that were predominant.
Total bacterial counts and each predominant genus
correlated with temperature, relative humidity, CO2, and
population density. It was found that the concentration
of CO2 had the greatest influence on the bacterial counts
in the campus, which indicated that ventilation played the
most important role in reducing the level of airborne
bacteria on the campus.
