 en CTX-M-9 group extended-spectrum β-lactamases in neonatal stool isolates: Emergence in India
Roy, S; Mukherjee, S; Singh, A K. & Basu, S

Abstract

The study reports for the first time the identification of CTX-M-14-like and CTX-M-27-like extended-spectrum β-lactamases (ESBLs) belonging to the CTX-M-9 group in Klebsiella pneumoniae check for this species in other resources and Escherichia coli check for this species in other resources isolated from the neonatal stool in India. The plasmid carrying the blaCTX-M-9 group in both the isolates was transferable. Till date, no other CTX-M group, except the CTX-M-1 group, has been reported from India. A total of 77% of the neonates had ESBL-producing K. pneumoniae or E. coli in their stool, and blaCTX-M-15 was the predominant ESBL gene. Although the CTX-M-9 group was found in the stool and did not cause infection, the detection of the CTX-M-9 group might be a prelude to future infections.
