No need for microgenocide!
An article from Nature Reviews Microbiology:
"Triclosan-containing 'antibacterial' soaps are no more effective at removing bacteria from hands than plain soaps, according to a recent study. Moreover, the use of such soaps could potentially lead to the emergence of cross-resistance to antibiotics. Alison Aiello and Stuart Levy carried out a systematic literature review of studies that had examined the effectiveness of commercially available antibacterial soaps and those that looked at the resistance outcomes of triclosan use. Commercially available antibacterial soaps typically contain triclosan, a phenoxyphenol, at between 0.1% and 0.45% weight per volume. Aiello and Levy found that, from the four available studies, there is no evidence to suggest that 'handwashing' for a normal duration with a soap that contains triclosan at these concentrations is any more effective at reducing the level of bacteria that are on hands, or preventing common infections, than washing with plain soap. In vitro studies have indicated that exposure to sub-lethal concentrations of triclosan can lead to antibiotic resistance in some bacterial species, but further research is required to assess whether this extends to the community use of triclosan-containing soaps. Clin. Infect. Dis.
So think twice before getting the stuff!
