Application

Phosphomycin, also known as Fosfomycin, is an antibiotic produced by Streptomyces fradiae. It is used to treat uncomplicated urinary tract infections. It is used for susceptibility studies of Klebsiella pneumoniae and to study in vitro susceptibility testing procedures for fosfomycin tromethamine.

Biochem/physiol Actions

Antibiotic that concentrates in kidney and bladder; reduces nephrotoxicity and ototoxicity of platinum-containing anti-tumor agents. Fosfomycin is a phosphoenolpyruvate analog that irreversibly inhibits UDP-GlcNAc enolpyruvyl tranferase (MurA), an enzyme involved in bacterial cell wall biosynthesis. As a result, the production of N-acetylmuramic acid, an essential element of the peptidoglycan cell wall, is inhibited.

Fosfomycin tromethamine (previously fosfomycin trometamol) is an orally administered fosfomycin which may be used for single-dose therapy of uncomplicated urinary tract infections. Fosfomycin tromethamine, norfloxacin, and trimethoprim-sulfamethoxazole inhibited greater than 90% of 352 bacterial isolates representing 25 different species; trimethoprim

In vitro activity of fosfomycin was evaluated against 68 bla(KPC)-possessing Klebsiella pneumoniae (KpKPC) isolates, including 23 tigecycline- and/or colistin-nonsusceptible strains. By agar dilution, 93% of the overall KpKPC were susceptible (MIC(50/90) of 16/64 microg/ml, respectively). The subgroup of 23 tigecycline-

Antibiotic combination therapies are important for the efficient treatment of many types of infections, including those caused by antibiotic-resistant pathogens. Combination treatment strategies are typically used under the assumption that synergies are conserved across species and strains, even though recent

Temperate phages can adopt either a lytic or lysogenic lifestyle within their host bacteria. It was recently shown that Bacillus-subtilis-infecting phages of the SPbeta group utilize a peptide-based communication system called arbitrium to coordinate the lysogeny decision. The occurrence of peptide-based
