Abstract

A. baumanii was not given much importance until recently when it started emerging as a serious threat in hospitals all over the world. Development of multiple drug resistance and ability to form extensive biofilms is considered as the major reasons behind this emergence. Hence it is the need of the hour to understand more about this ability exhibited by this pathogen. This study was designed with this aim in focus. Here the organism was isolated from the patients admitted in ICU and was identified by its phenotypic characterization and the antibiotic sensitivity testing was done by Kirby Bauer method. Further the biofilm forming ability of the organism was checked by growth on Congo red agar and by tube method and then the extend of bio film formation was checked on both plastic and glass tube. All the strains Isolated had the ability to form biofilms and were resistant to almost all the antibiotics tested. Plastic tube supported the formation of biofilms more than glass test tubes.

Keywords: Kirby Bauer method, red agar, plastic and glass tube.
