An extramural aero-bacteriological study was undertaken to determine typical concentrations of airborne culturable bacteria at the vicinity of a local hospital in the tropical environment of India. Hospital acquired infection is a common phenomenon; however, hospital as a source of infection for the surroundings community is yet to be established. Present aero-bacteriological investigation includes enumeration, identification, and numerical analysis of air borne culturable bacteria in hospital associated environment. Bacteria isolated from the environment during the present study were representative of normal micro flora of the skin, respiratory and gastro-intestinal tracts; it also includes the opportunistic pathogens like Acinetobacter and Flavobacterium species with the environmental non-pathogenic genera. In this study respirable and nonrespirable fraction of bacteria were also quantify. The Pearson correlation study shows that both temperature and humidity have an effect on tenacity and prevalence of the allbacterial type. A regression model with 67.15 % variance is also prepared in order to predict the bio-load for this atmosphere.KEY WORD: Aerosolization, Aero-bacteriological investigation, Enterobacteriaceae and Prediction.
