Bacteria Resistant to Last-Resort Antibiotic Also Evade Our Immune System
May 22, 2013 By Leave a Comment
Treatment of bacteria resistant to multiple antibiotics with a last-resort drug may be risky, a new study suggests, because developing resistance to this drug, called colistin, also allows bacteria to evade the human immune system. Bacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to… [Continue Reading]
