Molecular Detection and Epidemiology of Extended-Spectrum Beta-lactamase Genes Prevalent in Clinical Isolates of Klebsiella pneumoniae and E coli from Trinidad and Tobago

This first report of molecular characterization and epidemiology of ESBL subtypes in E coli and K pneumoniae isolates in Trinidad and Tobago shows that the CTX-M, mainly phylogenetically group 1 type, was most predominant. Most ESBL producing isolates were still susceptible to carbapenems and aminoglycosides and their spread appears to be polyclonal and clonally unrelated.


Objective: The epidemiology of Extended-spectrum beta-lactamase (ESBL) producing E coli and K pneumoniae is complex and varies among hospitals and countries. This study aimed at describing the molecular detection and epidemiology of ESBL subtypes prevalent in clinical isolates of K pneumonia and E coli in Trinidad and Tobago.
