Comparative Genomics of Strains Isolated from Different Ecological Niches.

The genome can change to adapt to different ecological niches. We compared four genomes from a Mexican hospital and 59 genomes from GenBank from different niches, such as urine, sputum, and environmental. The ST analysis showed that high-risk STs (ST235, ST773, and ST27) were present in the genomes of the three niches from GenBank, and the STs of Mexican genomes (ST167, ST2731, and ST549) differed from the GenBank genomes.

A Plasmid Carrying in Belonging to a Novel Resistance Plasmid Family.

and are the most detected plasmid-encoded carbapenemase genes in . Previous studies have reported plasmid sequences carrying variants, except . In this study, we aimed to characterize a plasmid carrying in a strain isolated from a Mexican hospital.

Characterization of antimicrobial resistance mechanisms in carbapenem-resistant carrying IMP variants recovered from a Mexican Hospital.

Purpose: infections in hospitals constitute an important problem due to the increasing multidrug resistance (MDR) and carbapenems resistance. The knowledge of resistance mechanisms in strains is an important issue for an adequate antimicrobial treatment. Therefore, the objective was to investigate other antimicrobial resistance mechanisms in MDR strains carrying , make a partial plasmids characterization, and determine if modifications in gene affect the expression of the OprD protein.
