Escherichia coli strains from Kenyan patients carrying conjugatively transferable broad-spectrum β-lactamase, qnr, aac(6′)-Ib-cr and 16S rRNA methyltransferase genes.

The article reports on the presence of highly resistant Escherichia coli strains in Kenya carrying transferrable genes conferring broad resistance to many classes of antibiotics. It mentions that the clinical strains were non-clonal and belonged to phylogenetic groups B1, B2 and D, with two B2 strains belonging to the ST131 clonal complex. It cites the resistance of donors and transconjugants to trimethoprim, tetracyclines and penicillins. It adds that isolates producing extended-spectrum β-lactamases (ESBL) were resistant to most cephalosporins.
