Tiwari S, et al. - Researchers aimed at comparing the effectiveness of 2 commonly used disinfectants, sodium hypochlorite and ethanol, against the planktonic and biofilm state of Staphylococcus aureus clinical isolates. In this work, sodium hypochlorite was proved to have superior efficacy in controlling both planktonic and biofilm states of growth in S aureus. Moreover, they observed characteristic morphologic changes in the strong biofilm that suggested its biofilm-specific activity.
