Escherichia coli ST2797 as a novel emerging extended-spectrum beta-lactamase Escherichia coli JournalSpectrum noragric ecoli Ecoli betalactamase
By Bhavana KunkalikarJun 5 2023Reviewed by Lily Ramsey, LLM In a recent study published in the Microbiology Spectrum Journal, researchers suggest that Escherichia coli ST2797 could potentially be a new type of extended-spectrum beta-lactamase Escherichia coli.
About the study The team conducted a study in Norway and found high levels of the emerging multi-resistant clones ST648 and ST131 in a sample of 3,123 E. coli isolates. These isolates were collected from urban wastewater which did not have any hospital or other related affluents. Related StoriesThe Center for Genomic Epidemiology pipeline was used to analyze the data and detect antibiotic resistance genes, multilocus sequence typing profile, and plasmid typing.
ESBL genes were detected in two of the ST2797 isolates. This indicated that ST2797 has the potential to disseminate and adapt to various ecological habitats. The ST2797 isolates analyzed exhibited genetic variations within themselves but were found to be more closely associated with each other in comparison to the ST2797 isolates in Enterobase.
