Background and Aims: Klebsiella pneumoniae is a gram negative opportunistic pathogen of nosocomial infections that causes pneumonia, urinary tract infection (UTI), meningitis, septicemia and diarrhea. The emergence and spread of carbapenemase producing Klebsiella pneumoniae often cause failure in the treatment of infections. The aim of this study was to evaluate the prevalence of carbapenemase ...

Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test...

Carbapenem-resistant Enterobacteriaceae (CRE) have spread globally and represent a serious and growing threat to public health. The introduction of rapid and sensitive methods for the detection of carbapenemase-producing bacteria is of increasing importance. The carbapenemase production can be detected using non-molecular methods (such as the modified Hodge test, the synergy test, the Carba NP ...

The aim of the present study was to investigate the molecular mechanism of carbapenem resistance of three imipenem-resistant isolates of Myroides odoratimimus recovered from two livestock farms of cows and pigeons by rectal swab in Lebanon in January 2014. Investigation of imipenem resistance of these isolates using the modified Hodge test, the EDTA test, the modified CarbaNP test and the matri...

The surveillance of Device associated infections in ICUs can reduce incidence of Nosocomial infections (NIs), healthcare cost & a better control of infections. Aims & Objectives: To know the occurrence of device associated infection rate in ICU and to know the bacterial profile of various devices associated infections. Materials and Methods: This study was conducted between October 2011 to May ...

background :    pseudomonas aeruginosa is a severe challenge for antimicrobial therapy, because of chromosomal mutations or exhibition of intrinsic resistance to various antimicrobial agents such as most β-lactams. we undertook this study to evaluate the existence of sme, aim and vim metallo-beta lactamases encoding genes among p. aeruginosa strains isolated from icu patients in al-zahra hospit...
