Background: Multidrug-resistant Acinetobacter baumannii is associated with life threatening nosocomial infections and hospital outbreaks. The organism is resistant to most commonly used antibiotics including carbapenems. Aim and Objectives: To study carbapenemase production among multidrug-resistant clinical isolates of A. baumannii. Material and Methods: Fifty multidrug-resistant A. baumannii ...
Antimicrobial resistance is frequently associated with clinical use of antibiotics. This close association suggests that efforts to manage our use of these potent agents can have an impact on the prevalence of resistance. Unfortunately, one size does not fit all when considering the response of bacterial pathogens to antimicrobial exposure. Measures that may prevent resistance in some species (...
OBJECTIVES Inhibitors of uridine diphosphate-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase (LpxC, which catalyses the first, irreversible step in lipid A biosynthesis) are a promising new class of antibiotics against Gram-negative bacteria. The objectives of the present study were to: (i) compare the antibiotic activities of three LpxC inhibitors (LPC-058, LPC-011 and LPC-087) and ...
Bacteria that produce the broad-spectrum Carbapenem antibiotic New Delhi Metallo-β-lactamase (NDM) place a burden on health care systems worldwide, due to the limited treatment options for infections caused by them and the rapid global spread of this antibiotic resistance mechanism. Although it is believed that the associated resistance gene blaNDM-1 originated in Acinetobacter spp., the role o...
An understanding of why certain Acinetobacter species are more successful in causing nosocomial infections, transmission and epidemic spread in healthcare institutions compared with other species is lacking. We used genomic, phenotypic and virulence studies to identify differences between Acinetobacter species. Fourteen strains representing nine species were examined. Genomic analysis of six st...
Background: Acinetobacter baumannii is the most prevalent strain in hospitals and different clinical departments. Objectives: The current study aimed to investigate the genetic characteristics and resistance mechanisms of A. baumannii isolated from clinical samples in Shaoxing people’s hospital affiliated to Zhejiang University, Shaoxing, China. Patients and Methods: Acinetobacter baumannii str...
The unambiguous identification of Acinetobacter strains, particularly those belonging to the Acinetobacter calcoaceticus-Acinetobacter baumannii complex, is often hindered by their close geno- and phenotypic relationships. In this study, monoclonal antibodies (MAbs) against the O antigens of the lipopolysaccharides from strains belonging to the A. calcoaceticus-A. baumannii complex were generat...
OBJECTIVES To assess the frequency and diversity of extended spectrum beta-lactamases (ESBLs) in the Champagne-Ardenne region France, and to identify genetic elements associated with the bla(CTX-M) genes. METHODS During 2004, all the non-duplicate isolates of Pseudomonas aeruginosa and Acinetobacter baumannii resistant to ceftazidime and of Enterobacteriaceae intermediate or resistant to ceft...
The study aim was to describe the emergence of carbapenem resistance and clonal complexes (CC), defined by multilocus sequence typing (MLST), in Acinetobacter baumannii in a surveillance system for meningitis. Starting in 1996 in an urban setting of Brazil, surveillance detected meningitis by Acinetobacter sp for the first time in 2002. Up to 2008, 35 isolates were saved. Carbapenem resistance ...
results two bacterial types, st208, and st218, were identified in all 140 samples. the st208 mainly came from icu and department of respiratory medicine, while st218 from department of plastic surgery; 70.21% of st208 and 84.78% of st218 were carbapenem-resistant acinetobacter baumannii (crab) and carbapenem-susceptible acinetobacter baumannii (csab), respectively. multidrug-resistance genes in...
