Pseudomonas aeruginosa isolates (n=183), collected from bacteraemic patients hospitalised in Sao Paulo Hospital (Brazil) during 2000-2001, were screened for susceptibility to antimicrobial agents. The polymyxins were the most active compounds (100% susceptibility), followed by amikacin and cefepime (59.0%), meropenem (57.4%), and imipenem and gentamicin (55.2%). Imipenem-resistant isolates were...
INTRODUCTION Polymyxins are antimicrobial agents capable of controlling carbapenemase-producing Klebsiella pneumoniae infection. METHODS We report a cluster of four patients colonized or infected by polymyxin-resistant and Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae. RESULTS Three patients were hospitalized in adjacent wards, and two were admitted to the intensive care...
Previously other groups had reported that Paenibacillus polymyxa NRRL B-30507 produces SRCAM 37, a type IIA bacteriocin with antimicrobial activity against Campylobacter jejuni. Genome sequencing and isolation of antimicrobial compounds from this P. polymyxa strain show that the antimicrobial activity is due to polymyxins and tridecaptin B1. The complete structural assignment, synthesis, and an...
TO THE EDITOR—Colistin, an “old” polymyxin antibiotic, is being used increasingly as a last-line therapy against infections caused by gram-negative bacteria that are resistant to other available antibiotics. Unfortunately, a multiplicity of ways of expressing doses is confounding the clinical use of colistin around the world. This is impacting the ability of clinicians to use the drug optimally...
