Characterization of microbial species in relation with device associated infection

Bhavna Sharma Grover, Anita Chhabra

Abstract :

The formation of bacterial biofilms on medical devices is a leading cause of infections in hospitalized patients. Characterizing these biofilms and identifying the bacterial species are of major importance. We studied the formation of biofilms on the inner surface of devices using microbiological culture techniques. The bacterial species were identified as a variety of gram–negetive bacilli, with a predominance of strains belonging to E.coli and Pseudomonas. The resistance pattern of isolated bacterial species were determined against selected antibiotics. Further their minimumal biofilm inhibitory concentration was also determined. The bacterial species on the devices were characterized by scanning electron microscopy. Microbiological analysis of the devices is required for true identification of the causative agents of device –associated infections. This approach, combined with a routine cytobacteriological examination allows for the complete characterization of biofilm–associated species, and also may help prevent biofilm formation in such devices and help guide optimum antibiotic treatment
