We report the first multidrug-resistant Proteus mirabilis strain producing the carbapenemase OXA-48 (Pm-OXA-48) isolated at Al-Shifa hospital in Gaza, Palestine. Draft genome sequencing of Pm-OXA-48 identified 16 antimicrobial resistance genes, encoding resistance to β-lactams, aminoglycosides, fluoroquinolones, phenicols, streptothricin, tetracycline, and trimethoprim-sulfamethoxazole. Complet...

ChromID extended-spectrum beta-lactamase (ESBL) culture medium is routinely used for screening ESBL producers. This medium was tested for detecting carbapenemase-producing Enterobacteriaceae isolates from a collection of reference strains and compared to the CHROMagar KPC culture medium previously evaluated for detecting KPC-producing isolates. Producers of IMP-, VIM-, and KPC-type carbapenemas...

Consecutive non-replicate clinical isolates (n=191) of carbapenem non-susceptible Enterobacteriaceae were collected from 21 hospital laboratories across Italy from November 2013 to April 2014 as part of the European Survey on Carbapenemase-producing Enterobacteriaceae (EuSCAPE) project. Klebsiella pneumonia carbapenemase-producing K. pneumoniae (KPC-KP) represented 178 (93%) isolates with 76 (4...

We investigated the resistance determinant of 13 clinical isolates of carbapenem-resistant Acinetobacter baumannii collected from a regional hospital in the north of Thailand. All isolates were multidrug resistant and produced the OXA-23 carbapenemase. The bla(OXA-23) gene was found adjacent to ISAba1. Furthermore, two isolates carried the metallo beta-lactamase gene, bla(IMP). The bla(OXA-23) ...

OXA-48 carbapenemase-producing organisms have emerged rapidly worldwide and may be transmitted through patients who receive medical care abroad. To our knowledge, this is the second case of OXA-48-producing Klebsiella pneumoniae isolated from a patient who had returned to Japan after receiving treatment abroad.

background and objectives: klebsiella pneumoniae is an opportunistic pathogen responsible for up to 10% of nosocomial infections. the emergence and spread of multidrug resistant k. pneumoniae , mostly due to the production of extended-spec- trum β-lactamases (esbl) and carbapenemases, is often responsible for antibiotic treatment failure of these infections. we compared the antibiotic resistanc...

Wildlife may harbour clinically important antimicrobial-resistant bacteria, but the role of wildlife in epidemiology bacterial infections humans is largely unknown. In this study, we aimed to assess dissemination blaKPC carbapenemase gene among and gulls Alaska. We performed whole-genome sequencing determine genetic context isolates from all four human carbapenemase-producing Enterobacteriaceae...

ST11 is a high-risk sequence type associated with carbapenem-resistant Klebsiella pneumoniae strains. Carbapenemase-producing hypervirulent K. (hvKp) are major concern as they harbour diverse range of pathogenicity traits. Here we describe the characteristics strain KP75w isolated from tertiary-care hospital in Pakistan. Antimicrobial susceptibility testing was performed by Kirby–Bauer disk dif...

A Drigalski agar-based culture medium containing an ertapenem, cloxacillin, and zinc sulfate (Supercarba medium) was tested for screening carbapenemase-producing members of the family Enterobacteriaceae. OXA-48 (n = 44), NDM (n = 25), VIM or IMP (n = 27), and KPC producers (n = 18) were detected with a low detection limit. Its overall sensitivity (95.6%) was higher than those of the currently a...

The in vitro activity of the novel antimicrobial peptide dendrimer G3KL was evaluated against 32 Acinetobacter baumannii (including 10 OXA-23, 7 OXA-24, and 11 OXA-58 carbapenemase producers) and 35 Pseudomonas aeruginosa (including 18 VIM and 3 IMP carbapenemase producers) strains and compared to the activities of standard antibiotics. Overall, both species collections showed MIC50/90 values o...
