Washington: A recent study has revealed that a new, drug-resistant strain of E coli is causing serious antimicrobial-resistant infections in the US.The new strain, ST131 has been reported in multiple countries and encountered all over the United States. In the study, researchers analyzed resistant E coli isolates collected during 2007 from hospitalized patients across the country. They identified 54 ST131 isolates, which accounted for 67 percent to 69 percent of E coli isolates exhibiting fluoroquinolone or extended-spectrum cephalosporin resistance.“If we could discover the sources of this strain, the transmission pathways that allow it to spread so effectively, and the factors that have led to its rapid emergence, we could find ways to intervene and possibly slow or halt this strain’s emergence,” said study author James Johnsonof VA Medical Center in Minneapolis.
“If this strain gains one additional resistance gene,” Dr Johnson added, “it will become almost untreatable and will be a true superbug, which is a very concerning scenario.”The findings were published in the Clinical Infectious Diseases. ANI
