orthodox and unorthodox clavulanate combinations against extended-spectrum beta-lactamase producers.clavulanate is a highly effective inhibitor of extended-spectrum beta-lactamases (esbls) in detection tests, but the commercial amoxycillin-clavulanate and ticarcillin-clavulanate combinations have borderline activity, at best, against most esbl producers. oxyimino-cephalosporin-clavulanate combinations are active in vitro against most esbl-producing escherichia coli and klebsiella spp. isolates at < or =1-2 mg/l but are compromised against enterobacter spp., whether esbl-producing or not, where ...200818154546
antibiotic policy and prescribing strategies for therapy of extended-spectrum beta-lactamase-producing enterobacteriaceae: the role of piperacillin-tazobactam.therapy of infections caused by extended-spectrum beta-lactamase (esbl)-producing bacteria with an antimicrobial to which they are resistant results in treatment failure, higher cost and increased mortality. the clsi recommends reporting esbl-producing strains of escherichia coli, klebsiella spp. and proteus spp. as resistant to all penicillin, true cephalosporin and monobactam antimicrobials, but as susceptible to beta-lactam-beta-lactamase inhibitor combinations, including piperacillin-tazobac ...200818154544
prevalence and clonality of extended-spectrum beta-lactamases in asia.asia is almost certainly a part of the world in which extended-spectrum beta-lactamases (esbls) have emerged de novo, with some early antimicrobial resistance studies showing high levels of the esbl phenotype, particularly among klebsiella, and most notably in china, korea, japan and india. there is a lack of genotyping studies but work from the late 1990s suggests that shv-5 and shv-12 were most common then, with only very rare reports of tem-related esbl genes. as in other parts of the world, ...200818154540
prevalence and spread of extended-spectrum beta-lactamase-producing enterobacteriaceae in europe.extended-spectrum beta-lactamases (esbls) represent a major threat among resistant bacterial isolates. the first types described were derivatives of the tem-1, tem-2 and shv-1 enzymes during the 1980s in europe, mainly in klebsiella pneumoniae associated with nosocomial outbreaks. nowadays, they are mostly found among escherichia coli isolates in community-acquired infections, with an increasing occurrence of ctx-m enzymes. the prevalence of esbls in europe is higher than in the usa but lower th ...200818154538
extended-spectrum beta-lactamases in north america, 1987-2006.extended-spectrum beta-lactamases (esbls) derived from the tem-1 beta-lactamase were first identified in the usa in outbreak strains of klebsiella pneumoniae in the middle to late 1980s, together with the shv-5 esbl. the tem-10, tem-12 and tem-26 enzymes have remained in us hospitals, but have been joined by other esbls that are variants of the shv-1 broad-spectrum beta-lactamase. in the most recent surveys from hospitals in the eastern part of the usa, the most prominent esbls have been the shv ...200818154537
extended-spectrum beta-lactamases and the permeability barrier.the outer membrane of gram-negative bacteria represents a barrier for penetration of hydrophilic compounds. loss of porins (water-filled protein channels) contributes to antimicrobial resistance, particularly when additional mechanisms of resistance are expressed. many studies on the structure and regulation of porins in escherichia coli k-12 are available, but there is little information concerning clinical isolates of this species. in klebsiella pneumoniae, two major porins, ompk35 and ompk36, ...200818154531
