Multilocus sequence typing reveals genetic diversity of carbapenem- or ceftazidime-nonsusceptible Pseudomonas aeruginosa in China.

چکیده
It is unclear whether the genetic background of drug-resistant Pseudomonas aeruginosa was disseminated from a certain clone. Thus, we performed MLST (multilocus sequence typing) of 896 P. aeruginosa isolates that were nonsusceptible to imipenem, meropenem, or ceftazidime. This revealed 254 sequence types (STs), including 104 new STs and 34 STs with novel alleles. Thirty-three clonal complexes and 404 singletons were found. In conclusion, drug-resistant P. aeruginosa clones can be developed from diverse genetic backgrounds.

BACKGROUND Pseudomonas aeruginosa is an important nosocomial pathogen that exhibits multiple drug resistance with increasing frequency, especially to carbapenems making patient treatment difficult. Carbapenem-resistance may be caused by porin gene mutations, active drug efflux, and carbapenemase production. This study evaluated the incidence of genes responsible for carbapenemase production in ...

For a better understanding of the multidrug resistant Pseudomonas aeruginosa (MDR-PA) epidemiology in mainland China, a nationwide surveillance network of 27 tertiary hospitals was established. Non-duplicate MDR-PA isolates from 254 cases of nosocomial infections, were collected during the period August 2011 to July 2012. Minimum inhibitory concentrations (MICs) of nine antimicrobial agents wer...

Ceftazidime is one of the few cephalosporins with activity against Pseudomonas aeruginosa Using whole-genome comparative analysis, we set out to determine the prevalent mechanism(s) of resistance to ceftazidime (CAZ) using a set of 181 clinical isolates. These isolates represented various multilocus sequence types that consisted of both ceftazidime-susceptible and -resistant populations. A pres...

Carbapenems are a mainstay of treatment for infections caused by Pseudomonas aeruginosa. Carbapenem resistance mediated by metallo-β-lactamases (MBLs) remains uncommon in the United States, despite the worldwide emergence of this group of enzymes. Between March 2012 and May 2013, we detected MBL-producing P. aeruginosa in a university-affiliated health care system in northeast Ohio. We examined...
