Background: Pseudomonas aeruginosa is the causing agent of many hospital infections and metallo-beta-lactamases (MBL) are being reported with increasing frequency. The aim of this study was to determine the frequency of metallo-&beta-lactamases (MBL) and VIM-1 gene in multidrug-resistant strains of P. aeruginosa isolates and to compare the methods of phenotypic and molecular detection. Materia...

conclusions regarding the importance of metallo-beta-lactamase (mbl) produced by pseudomonas spp. isolated from hospitals, quick identification of clinical samples should be considered as an important and basic step to treat and control infections caused by pseudomonas spp. results strains with mic > 4 µg/ml were investigated by phenotypic and genotypic methods. in the current study the rate of...

Acquired resistance is through the production of AmpC Beta Lactamases (AmpC), Extended Spectrum Beta Lactamases (ESBL) and Metallo Beta-Lactamases Enzymes (MBL). Resistance to β-lactam antibiotics is associated with production of ESBL which can hydrolyze oxyimino β-lactams such as cefotaxime, ceftriaxone, ceftazidime and monobactams, however, without any effect on cephamycins, carbapenems and r...

This study was conducted to detect the prevalence of Metallo-Beta-Lactamases (MBLs) and Extended Spectrum Beta-Lactamases (ESBLs) in bacterial isolates from clinical community settings two communities Delta State, Nigeria. Eighty four obtained blood, urine, wound stool patients subjects were analyzed identified by standard microbiological methods. Carbapenemase detection carried out using modif...

Acquired metallo-beta-lactamases (MBLs) can confer broad-spectrum beta-lactam resistance (including carbapenems) not reversible by conventional beta-lactamase inhibitors and are emerging resistance determinants of remarkable clinical importance. In 2001, multidrug-resistant Pseudomonas aeruginosa carrying bla(VIM) MBL genes were found to be widespread (approximately 20% of all P. aeruginosa iso...

BACKGROUND Ventilator-Associated Pneumonia (VAP) is the most frequent intensive-care-unit (ICU)-acquired infection. The aetiology of VAP varies with different patient populations and types of ICUs. METHODOLOGY A prospective study was performed over a period of 15 months in a tertiary care hospital to determine the various aetiological agents causing VAP and the prevalence of multidrug resista...

Background: Infectious by Pseudomonas aeruginosa has spread worldwide and metallo-beta-lactamases (MBL) are being reported with increasing frequency. The aim of this study was to investigate the antibiotic susceptibility and distribution of blaVIM and blaIMP genes in P. aeruginosa isolates from Zanjan Province of Iran. Methods: A total of 70 P. aeruginosa isolates were identified from patients ...
