Abstract

Introduction and Aim: Disinfectants play a vital role in the prevention of nosocomial infections. A variety of disinfectants with different mechanism of action are available in the market. Most of the hospitals and health care centres select the disinfectants trusting the claims made by the manufacturers which may not be authentic.

 

Materials and Methods: Plenty of standardised in-house disinfection testing methods are available but because of their complex procedure most of them are not feasible. Thus, in our study we employed a simple “quantitative suspension method” for testing the efficiency of the disinfectants. Commercially available disinfectants- Srivlon, Emplura, Hospal-OT, and NICE were tested against three nosocomial pathogens - Pseudomonas aeruginosa, MRSA, and Candida albicans.

 

Results: In this study, the commercial disinfectants wereacted effectively against all the three organisms. Hospal-OT had the maximum bactericidal activity followed bySrivlondisinfectant.

 

Conclusion: Our study concluded that all the four commercial disinfectants were acted against the pathogens viz., Pseudomonas aeruginosa, MRSA and Candida albicans. Among four disinfectants, Srivlon needs a regular monitoring because of poor performance. Therefore, the proper usage of concentration and contact period of disinfectant will provide an efficient action against the pathogenic microbial population.
