Effect Of Virkon Disinfectant Brand Of Potassium Monoperoxysulphate On Multiply-Resistant, Hospital-Acquired Clinical Isolates

In the Nigerian market are many brands of disinfectants with varying efficacy against bacteria, fungi and viruses. Recently Virkon brand of potassium monoperoxysulphate (Antec, UK) was introduced. The Kelsey -Sykes test was carried out to determine the efficacy of Virkon against standard bacterial strains and hospital-acquired clinical bacterial isolates (Pseudomonas aeruginosa, Methicillin- resistant Staphylococcus aureus, Candida spp., High-level gentamicin resistant Enterocoocus faecalis, Multiply-resistant Escherichia, Coli, and Klebsiella pneumoniae.)At the contact time of 5min, 10min, 15min, 20min, The effect of organic matter and 7-day storage on pre-diluted disinfectant was also determined. Virkon prevented the growth of all the organisms tested even after storage for 7-days. It' activity was not affected by organic matter. Virkon is very effective against Candida Spp; gram-positive and gram-negative bacteria. (J. of the Nigerian Association of Infection Control, 2000, 3(1): 34-35)
