متن کاملAcrAB efflux pump plays a role in decreased susceptibility to tigecycline in Morganella morganii.
Transposon mutagenesis of a clinical isolate of Morganella morganii, G1492 (tigecycline MIC of 4 microg/ml), yielded two insertion knockout mutants for which tigecycline MICs were 0.03 microg/ml. Transposon insertions mapped to acrA, which is constitutively overexpressed in G1492, suggesting a role of the AcrAB efflux pump in decreased susceptibility to tigecycline in M. morganii.
متن کاملFirst Emergence of acrAB and oqxAB Mediated Tigecycline Resistance in Clinical Isolates of Klebsiella pneumoniae Pre-Dating the Use of Tigecycline in a Chinese Hospital
Tigecycline is one of the few therapeutic options for treating infections caused by some multi-drug resistant pathogens, such as Klebsiella pneumoniae. However, tigecycline-resistant K. pneumoniae has been discovered recently in China. From 2009 to 2013, nine tigecycline-resistant K. pneumoniae isolates were identified in our hospital. Six of nine strains were identified before using tigecyclin...
متن کاملRoles of Salmonella multidrug efflux pumps in tigecycline resistance.
OBJECTIVES salmonella enterica strains exhibiting decreased susceptibility to tigecycline have been reported. In this study, we sought to elucidate the roles of Salmonella multidrug efflux pumps and AcrAB regulators in tigecycline resistance. METHODS we examined the involvement of multidrug efflux pumps and AcrAB regulators in resistance to tigecycline and other glycylcyclines by determining ...
متن کاملEmergence of Ciprofloxacin Resistance Among Pseudomonas Aeruginosa Isolated from Burn Patients
Background: Increasing resistance of Pseudomonas aeruginosa to ciprofloxacin in ICU/burn units has created a problem in the treatment of infections caused by this microorganism. Methods: Fifty P. aeruginosa strains were isolated from burn patients hospitalized in the Kerman Hospital during May 1999-April 2000 and were tested for in-vitro sensitivity to different antibiotics by disc diffusion br...
