Evolution in action: Dissemination of tet(X) into pathogenic microbiota

In a recent publication by Leski et al. (2013), the authors reported the occurrence of multidrug-resistant tet(X)-containing bacterial strains in a hospital in Sierra Leone. Among 52 clinical isolates, 11 (21%) have been confirmed tet(X)-positive. All the positive strains have been isolated from urinary tract infections and identified as Enterobacter cloacae, Comamonas testosteroni, Escherichia coli, Klebsiella pneumoniae, Delftia acidovorans, Enterobacter sp., and other members of Enterobacteriaceae and Pseudomonadaceae (Leski et al., 2013)....
