Sunday, February 11, 2007Healthy volunteers who took one of two antibiotics from a class called macrolides had a rapid and dramatic spike in antibiotic-resistant streptococci in their mouths. Swabs taken at 28 days, 42 days and 180 days after treatment β which was three days for one antibiotic and seven days for another β showed more than the majority of streptococci in their mouths were resistant to macrolides even at 180 days. βIt . . . should serve as a wake up call for individual prescribing physicians, nurse practitioners, midwives, dentists and others that inappropriate use of antibiotics does have consequences,β said Dr. John Conly, former chair of the Canadian Committee on Antibiotic Resistance and head of the department of medicine at Foothills Medical Centre in Calgary. You can't even read the abstract at The Lancet without registering, but the study participants were treated with azithromycin (Zithromax) and clarithromycin (Biaxin). The study was funded by Abbot, the makers of Biaxin, but it didn't really show any benefit for their drug. The question is, how do other classes of antibiotics compare? It's very likely one would see the same effect with penicillins or quinolones. posted by Sydney on 2/11/2007 07:59:00 AM 0 comments 0 Comments: |
