background :   ampc beta lactamases play a significant role in creating resistance to third generation cephalosporins worldwide. they mostly express on chromosome of enterobacteriaceae especially escherichia coli and cause consequential problem in clinical treatment and lead to failure in diagnosis and phenotypic test recommended by clinical and laboratory standards institute.   methods : total...

In the literature, only three Brevundimonas diminuta environmental isolates carrying metallo-β-lactamase genes were recently published. However, so far, no B. diminuta clinical isolates carrying these carbapenem resistance genes have been described. Here we report the first VIM-2 metallo-β-lactamase-producing B. diminuta clinical isolate obtained from an immunocompromised patient.

The purpose of the study was to examine prevalence Escherichia coli in shrimps and mussels, determine distribution β-lactam, aminoglycoside, quinolone, multi-drug resistance phenotypically genotypically E. isolates obtained from mussels Istanbul. Faecal samples were collected (n = 96) Marmara Sea coastline fish markets For detection antibiotic susceptibilities, seven groups used. β-lactam...

Background: Acinetobacter baumannii is a highly virulent bacterium. It causes opportunistic and nosocomial infections and is a threat to healthcare settings. It has also developed multidrug resistance (MDR) capacity. The nosocomial bacteria and antibiotic resistance are primordial and a significant public health concern. These bacteria and their threat can be prevented by reducing infected food...

BACKGROUND Metallo-β-lactamase-production among Gram-negative bacteria, including Pseudomonas aeruginosa, has become a challenge for treatment of infections due to these resistant bacteria. OBJECTIVES The aim of the current study was to evaluate the metallo-β-lactamase-production and carriage of bla-VIM genes among carbapenem-resistant P. aeruginosa isolated from burn wound infections. PATI...

Ceftazidime-resistant Klebsiella pneumoniae strains began to appear when ceftazidime usage was increased in two unrelated Chicago hospitals. These strains produced a beta-lactamase with an isoelectric point of 5.6 (RP-5.6) and strong hydrolyzing activity against ceftazidime. Two different restriction digest profiles were associated with the ceftazidime resistance plasmids. A second beta-lactama...

Objective(s): Pseudomonas aeruginosa is one of the most important nosocomial pathogens causing a high rate of mortality among hospitalized patients. Herein, we report the prevalence of antibiotic resistance genes, class 1 integrons, major virulence genes and clonal relationship among multidrug- resistant (MDR) P. aeruginosa, isolated from four referral hospitals in the...

b ackg r oun d : pseudomonas aeruginosa is one of the most important oppor- tunistic pathogens responsible for various types of infections. children suffer significant morbidity and mortality due to nosocomial infections. the aim of this study was to investigate the presence of class1 integron, blabel, blaper, blakpc, blavim, blaimp and blaoxagroup-1  genes among p. aeruginosa isolates at child...
