(2011-12-22)

World first study shows that some microorganisms can bend the rules of evolution
The dominant thinking in evolution focuses on inheritance between parent and offspring - or 'vertical gene transfer (VGT)'. But now scientists are paying more attention to 'horizontal gene transfer (HGT)': the transmission of DNA other than from parent to offspring, as this transfer can tell us about the evolution of a number of other organisms such as bacteria. It can also help us to better understand antibiotic resistance. (2020-10-13)

Outpatients, hospital patients face growing, but different problems with antibiotic resistance
A new study concludes that problems with antibiotic resistance faced by outpatients may be as bad as those in hospitalized patients, and that more studies of outpatients are needed -- both to protect their health and to avoid inappropriate or unnecessary drug use. (2013-04-18)

(2007-07-26)

Supermarket produce harbors antibiotic-resistance genes
Researchers from the Julius Kühn Institut, Germany have found that produce is a reservoir for transferable antibiotic resistance genes that often escape traditional molecular detection methods. These antibiotic resistance genes might escape cultivation-independent detection, but could still be transferred to human pathogens or commensals. The results, which highlight the importance of the rare microbiome of produce as a source of antibiotic resistance genes, are published November 6 in the open-access journal, mBio. (2018-11-06)
