BACKGROUND & OBJECTIVES Carbapenem-resistant Acinetobacter spp. have gained increasing significance as opportunistic pathogens in hospitalized patients. Carbapenem resistance is often associated with the loss and/or decrease in outer membrane proteins (OMP) and overexpression of multidrug efflux systems. However, carbapenem-hydrolysing beta-lactamases of Ambler Class B (metallo-enzymes) and Amb...

Background: Increase in antimicrobial-resistant bacteria continues to be challenge physicians. Particularly, multidrug-resistant (MDR) gram-negative bacilli (GNB), such as extended-spectrum beta-lactamase (ESBL)-producers and carbapenem-resistant pathogens, are becoming a major human health problem globally.Current Concepts: Gram-negative have developed resistance via mechanisms encoding AmpC b...

Two hundred and thirty isolates of Pseudomonas aeruginosa were obtained from samples of patients having diabetes (75%), cancer (20%), and both diabetes and cancer (5%) who were admitted to a tertiary care hospital in Western India from January to December 2006. These isolates were tested for susceptibility to antipseudomonal drugs and considered to be resistant to carbapenem when the zone of in...

Antibiotic resistance in conjunction with the erosion of the drug development pipeline may lead us into a bleak future, a "post-antibiotic era." Because of a shortage of studies addressing treatment options for multidrug-resistant Gram-negative (MDRGN) infections in children, data must be extrapolated from the adult literature. However, even adult studies are limited by significant methodologic...

Clinical isolates of Klebsiella pneumoniae resistant to carbapenems are being isolated with increasing frequency. Loss of the expression of the major nonspecific porins OmpK35/36 is a frequent feature in these isolates. In this study, we looked for porins that could compensate for the loss of the major porins in carbapenem-resistant organisms. Comparison of the outer membrane proteins from two ...

Antimicrobial resistance is becoming one of the greatest challenges to public health worldwide. Infections by antimicrobial-resistant organisms could result in the failure of treatment, increased medical costs, prolonged hospital stays, and an increased socioeconomic burden. Antimicrobial usage in Korea remains heavy, even after much effort to reduce their use. According to the Korean antimicro...

Background and objectives: Carbapenem-resistant and biofilm producing Enterobacteriaceaeare a major health problem. This study was carried to determine the antibacterial and antibiofilm activity of grape seed extract (GSE) against carbapenem-resistant and biofilm producing Enterobacteriaceae isolates. Methods: Antibiotics susceptibility pattern...

INTRODUCTION The objective of the present study was to analyse secular trends in antibiotic consumption and resistance data from a network of 53 intensive care units (ICUs). METHODS The study involved prospective unit and laboratory-based surveillance in 53 German ICUs from 2001 through 2008. Data were calculated on the basis of proportions of nonduplicate resistant isolates, resistance densi...
