Abstract

Plasmids are the main vectors of resistance and virulence genes in Enterobacteriaceae and plasmid typing is essential for the analysis of evolution, epidemiology and spread of antibacterial resistance. The PCR-Based Replicon Typing (PBRT), developed by Carattoli et al. in 2005, was an efficient method for plasmid identification and typing in Enterobacteriaceae. The 2005 PBRT scheme detected 18 replicons in 8 PCR reactions. Recently, the identification of novel replicons and plasmid types requested an update of the PBRT scheme. A commercial PBRT-KIT was devised for the identification of 28 different replicons in 8 multiplex PCRs. Here we report sensitivity and specificity of the PBRT-KIT carried out in comparison with the 2005 PBRT. The analysis of plasmid content was performed on forty-two enterobacterial strains from different sources, containing different replicon content. The 2005 PBRT identified replicons in 76.2% of the strains. The PBRT-KIT detected replicons in 100% of the analyzed strains, demonstrating increasing sensitivity and specificity of the commercial test with respect to the former 2005 PBRT scheme.
