چکیده

Fosfomycin, [L-(cis)-1, 2-epoxypropyl phosphonic acid] (FOM), a broad spectrum antibiotic produced by some strains of Streptomyces species1), acts as a phosphoenolpyruvate analog and irreversibly inhibits phosphoenolpyruvate UDP-N-acetylglucosamine (UDPG1cNAc)-3-O-enolpyruvyl transferase, an enzyme which catalyzes the first step of peptidoglycan biosynthesis2). FOM enters susceptible bacteria by means of two dif-

Molecular Monitoring of Fosfomycin Resistance in Escherichia coli Strains Isolated from Patients with Urinary Catheters in north-east of Iran

Introduction: Urinary tract infection is a common nosocomial infection that has recently become difficult to treat because of the increased emergence of multi-drug resistant strains. This study aims to determine the minimum inhibitory concentration, and molecular pattern of resistance to fosfomycin in Escherichia coli isolates originated from patients hospitalized with urinary tract infection i...

Prevalence of fosfomycin resistance among CTX-M-producing Escherichia coli clinical isolates in Japan and identification of novel plasmid-mediated fosfomycin-modifying enzymes.

We evaluated the in vitro activity of fosfomycin against a total of 192 CTX-M beta-lactamase-producing Escherichia coli strains isolated in 70 Japanese clinical settings. Most of the isolates (96.4%) were found to be susceptible to fosfomycin. On the other hand, some of the resistant isolates were confirmed to harbor the novel transferable fosfomycin resistance determinants named FosA3 and FosC...

Fosfomycin Resistance in Escherichia coli, Pennsylvania, USA

Fosfomycin resistance in Escherichia coli is rare in the United States. An extended-spectrum β-lactamase-producing E. coli clinical strain identified in Pennsylvania, USA, showed high-level fosfomycin resistance caused by the fosA3 gene. The IncFII plasmid carrying this gene had a structure similar to those found in China, where fosfomycin resistance is commonly described.

Fosfomycin resistance plasmids do not affect fosfomycin transport into Escherichia coli.

Escherichia coli cells carrying fosfomycin resistance plasmids were able to take up fosfomycin from the medium to the same extent as plasmid-free bacteria. The antibiotic entered the plasmid-harboring cells by means of the glpT and uhp transport systems, as is the case with susceptible bacteria. Active fosfomycin could be detected in soluble extracts of cells which had previously been incubated...

Antibiotic susceptibility of enterohemorrhagic Escherichia coli O157:H7 isolated from an outbreak in Japan in 1996.

The antibiotic susceptibilities of 43 strains of Escherichia coli O157:H7 identified in the summer of 1996 in Japan were investigated. Growth of 90% of O157 strains was inhibited at a concentration of < or = 0.5 micro/ml by several agents including fosfomycin with glucose-6-phosphate.
