Comparative Efficacies of Disinfectants against Clinical and Non Clinical Microorgansms

Microbial population on an inanimate objects like eating utensils and surgical instruments are main causes of hospital acquired infections. This work focused on comparative efficacies of disinfectants (Hydogen peroxide, Hypo and Izal) against clinical and non clinical microorganism. The disinfectant were tested against different microorganisms namely; clinical S. aureus, clinical C. albicans, non clinical S. cerevisiae and non clinical lactobacillus spp. The microbicidal activities of disinfectants were evaluated by examing the viability of cells after 24hr period of contact. The result revealed that hydrogen peroxide has the higher potency, most active and exhibited pronounced activity against lactobacillus and S.aureus. While Hypo and lzal has less activity against S. cerevisiae and C. albicans. Microbicdal activities of disinfectants were more pronounced on bacteria than fungi. This hydrogen peroxide can effectively replace the hypo and lzal employed in this study.
