A family of highly drug-resistant and potentially deadly bacteria may be spreading more widely—and more stealthily—than previously thought, according to a new study from Harvard T.H. Chan School of Public Health and the Broad Institute of MIT and Harvard. Researchers examined carbapenem resistant Enterobacteriaceae (CRE) causing disease in

four U.S. hospitals. They found a wide variety of CRE species. They also found a wide variety of genetic traits enabling CRE to resist antibiotics, and found that these traits are transferring easily among various CRE species. The findings suggest that CRE is more widespread than previously thought, that it may well be transmitting from person to person asymptomatically, and that genomic surveillance of these dangerous bacteria should be increased.
