Antibacterial Soaps Still Terrible

This article by Beth Mole is a fairly detailed summary of recent research on the effects of antimicrobial soaps. As we have mentioned before on microBEnet, antimicrobials increase resistance in the environment, wildlife, and people. In addition, the soaps are often not used for long enough to confer a benefit.

Acquired Resistance to Ultraviolet Germicidal Irradiation

By Amanda Makowiecki Miller Research Group University of Colorado, Boulder With drug resistant bacteria becoming a growing problem, alternative methods are being pursued to decontaminate air and surfaces; ultraviolet germicidal irradiation (UVGI) is one of these methods. UVGI uses short wavelength light in order to disrupt the genetic material of microorganisms, this disruption either kills …
