Background: Cephalosporins are major antimicrobials used to treat serious infections. However, their effectiveness is being compromised by the emergence of extended spectrum beta lactamases (ESBL). The present study was aimed characterize ESBL producing Escherichia coli from healthy and diarrheic cattle calves. Methods: A total 52 rectal swabs were collected calves between August 2019 March 202...
New extended-spectrum beta-lactamase GES-11 was detected in Acinetobacter baumannii BM4674. The enzyme conferred resistance to beta-lactams, including aztreonam, and reduced susceptibility to carbapenems. The structural gene was part of a class 1 integron borne by self-transferable plasmid pIP847. GES-type beta-lactamases have not been reported previously in A. baumannii.
