ABSTRACT

Air sample from various wards of different hospitals of Allahabad city were analyzed for the incidence of pathogenic microorganisms. Evaluation of isolates for detection of selected pathogen in various samples. Staphylococcus aureus (43.85%) gave highest incidence, which causes major microbial infection. Least incidence was found to be of Pseudomonas aeruginosa (8.9%). Antibiotic susceptibility pattern of the isolated pathogen showed highest resistance against Gentamycin and Methicillin. Imipenem was found to be most effective against all the isolates. There is a pressing need for a continued surveillance that must be applied periodically to detect possible changes in the level of microorganism. Monitoring of multidrug resistance pattern is also required for these bioaerosols, along with adequate ventilation control and the occupant density.
