Millions of people use antibacterial soap daily in order to stay healthy. Â This, it turns out, may actually do much more harm than good by contributing to the spread of drug-resistant disease.
Products made using triclosan â a common antibiotic found in everything from hand soap to cleaning wipes to toys â are among University of Texas microbiologist Marvin Whiteleyâs biggest pet peeves. âThe problem with that antibiotic is that itâs really not that active against a lot of the bugs youâd hope it would be,â says Whiteley, a professor of molecular biosciences.
But itâs not triclosanâs ineffectiveness that bugs Whiteley. Itâs that it weakens other antibiotics. âBacteria that are susceptible to triclosan become resistant to it, but they also become resistant to antibiotics you might get at the doctorâs office. So youâre proliferating antibiotic resistance,â he warns. âWeâre putting millions of pounds of this stuff into the environment.â

New Delhi Metallo-beta-lactamase-1 (NDM-1) is an enzyme that makes bacteria resistant to a broad range of antibiotics. These include the antibiotics of the carbapenem family, which are a mainstay for the treatment of antibiotic-resistant bacterial infections.Â
