Disinfectants efficacy on bacteria with the contaminants

ABSTRACT

The study was carried out to determine the effect of contaminants on the efficacy of routinely used disinfectants on bacteria and call on attention of hospital staff and medical care personnel for correct usage of disinfectants. Disinfectant efficacy of Hibitane, Osban, Ethanol, Isodine and Tego 51 on organisms such as P. aeruginosa, E. Cole, S. aureus and B. subtilis contaminated with organic substances such as human blood, egg white and animal oil were investigated. The disinfectant efficacy was also determined on clinical specimens. 70
