Original Paper


An investigation of the air quality and the quantity of airborne microbes was conducted in a private and a government tertiary health care centre of Davanagere in the month of November 2011 to assess the level of air borne pathogens. Using a Merck Microbial Air Sampler MAS-100NT, samples were collected in the morning and in the evening from the different environs of the private and government tertiary health care centre. The media used for the study of fungi was sabouraud dextrose agar. Aspergillus spp, Curvularia spp, Alternaria spp, Penicillium spp, Rhizopus spp, Nigrospora spp, and Fusarium spp were found in either of the tertiary health care centre. Aspergillus spp was dominant in the Government tertiary health care centre, and Alternaria spp and Curvularia spp were dominant in the private tertiary health care centre. For the bacteria, quantitative enumeration was done using soyabean casein digest agar and selective media like Escherichia coli and coliform agar and urinary tract infection agar were used in qualitative enumeration. Selected pathogens like E. coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella enteritidis, Staphylococcus aureus, Proteus mirabilis, and Entirococcus faecalis were found in either of the tertiary health care centre. Maximum number of fungi and bacteria were isolated from emergency ward and general ward of government and private health care centre. There was also considerable difference in the morning and in the evening.
