Abstract We spend approximately 90% of our life indoors, yet we know little about the source and diversity of microbes in built
environments. In the present study, the bacterial contamination of household and school environment surfaces was studied.
Total APCs in all the swab samples ranged from geometric mean of 10 to 10 5
CFU/cm
2
/ml. This study found kitchens
to have the greatest degree of bacterial contamination, followed by bath rooms. Toilets had less bacterial contamination
than was expected. No significant difference in bacterial load was observed between the house and school environment
surfaces. Among the five major pathogens examined, Staphylococcus. aureus was the only pathogen detected. The most
dominant bacteria were Staphylococcus, Acinetobacter, Bacillus sp., Corynebacterium, Micorcoccus, Microbacterium,
Aquinicola, Brevundimonas, Enterobacter, Kocuria, Leptothrix, Roseomonas, Serratia, Sphingomonas, and Candidawhich
are typically associated with human skin and ubiquitous in environment. This study provides a preliminary scenario of
bacterial level in home and school environment surfaces.
