VINEGAR CAN HELP FIGHT DRUG-RESISTANT
TB:
Acetic acid, an active ingredient in
vinegar, can be used as an inexpensive and non-toxic disinfectant against drug-resistant
tuberculosis (TB) bacteria, scientists say. Acetic acid can effectively kill mycobacteria,
even highly drug-resistant mycobacterium tuberculosis, according to an
international team of researchers from Venezuela, France and US. Work with
drug-resistant tuberculosis bacteria carries serious biohazard risks.
Chlorine bleach is often used to disinfect TB cultures and clinical samples, but bleach is toxic and corrosive, researchers said. Others effective commercial disinfectants can be too expensive for TB labs in the resource-poor countries where the majority of TB occurs, they said. Mycobacteria are known to cause tuberculosis and leprosy, but non TB mycobacteria are common in the environment, even in tap water, and are resistant to commonly used disinfectants.
