Real-time PCR testing for blaKPC, blaNDM, blaVIM, blaIMP, and blaCTX-M was performed on rectal swabs obtained from residents of two long-term acute-care facilities. While blaKPC was detected in 69/102 swabs (67.6%), testing for four other targets increased the positivity rate for a broad-spectrum β-lactamase to 73.5% (McNemar's P = 0.03).

Pseudomonas strain WCHP16 recovered from hospital sewage in West China Hospital, Chengdu, China was found to carry two carbapenemase genes blaIMP-25 and blaVIM-2 Here, we report its 5.7-Mb draft genome sequence, comprising 141 contigs and an average 59.53% G+C content. The genome contained 5,504 coding sequences and 67 tRNA genes.

Providencia stuartii is frequently associated with nosocomial outbreaks and displays intrinsic resistance to many commonly used antimicrobials. We report here the draft genome sequence of a P. stuartii strain carrying acquired resistance genes conferring panresistance to cephalosporins (blaSHV-5 and blaVEB-1), carbapenems (blaVIM-1), and aminoglycosides (rmtB) involved in an outbreak in Greek h...

During the last years, outbreaks and countrywide spread of isolates producing -lactamases of the AmpC type or carbapenemases have been reported (1, 2). We detected three Proteus mirabilis isolates with reduced susceptibility to cephalosporins and carbapenems at the Alexandrovska University Hospital in Sofia. They were isolated between November 2011 and January 2012 from the urine of three patie...

BACKGROUND Cystic Fibrosis (CF) is an autosomal recessive genetic disorder in white populations caused by mutation in a gene that encodes Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein. Since frequent respiratory tract infections are the major problem in patients with CF, obligation to identify the causative bacteria and determining their antibiotic resistance pattern is cru...

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 ...

results the most effective agent against the studied isolates was colistin. by cddt, it was found that among 278 imipenem resistant p. aeruginosa strains, 178(64.02%) were mbl producers. the blaimp-1 and blavim-1 genes were detected in 30(16.8%) and 52(29.2%) of p. aeruginosa isolates, respectively. result of 187 imipenem resistance a. baumannii strains showed that 85(45.4%) were mbl producers....

background & objectives: pseudomonas aeruginosais one of the most important causes of nosocomial infections particularly in immunodeficient patients. several antibiotics such as betalactams, aminoglycosides and quinolones are used for the treatment of infections caused by this organism, but the prevalence of multidrug resistant strains has been reported frequently. beta lactamase production is ...
