Due to the limited information of the contribution of various antibiotic resistance mechanisms in clinical Burkholderia cepacia complex isolates, Antibiotic resistance mechanisms, including integron analysis, identification of quinolone resistance-determining region mutations, measurement of efflux pump activity, and sequence analysis of efflux pump regulators, were investigated in 66 clinical ...

Antibiotic resistance is a phenomenon in which antibiotic used to treat bacteria becomes useless due to resistance mechanism. Increased drug resistance and occurrence of Multiple Drug Resistance in bacteria specificity nosocomial and Urinary Tract Infection bacteria has reduced the possibilities of treating these infectious diseases. Efflux pumps are one of the major mechanism of MDR in bacteri...

Bacterial efflux pumps are active transport proteins responsible for resistance to selected biocides and antibiotics. It has been shown that production of efflux pumps is up-regulated in a number of highly pathogenic bacteria, including methicillin resistant Staphylococcus aureus. Thus, the identification of new bacterial efflux pump inhibitors is a topic of great interest. Existing assays to e...

Background: Appearance of multi-drug resistance (MDR) Acinetobacter baumannii imposes limitation on antibiotic therapy in patients. Detection of MDR A. baumannii can play a crucial role to prevent MDR strains spreading in hospitals. The aim of this study was determination the efflux pumps gene expression in tigecyclin resistance strains in collected isolates from selected training hospitals in ...

OBJECTIVES Acinetobacter baumannii has emerged as an important nosocomial pathogen in hospitalized patients, and causes a multitude of infections with significant morbidity and mortality. The aim of this study was to elucidate the role of a novel efflux pump in A. baumannii. METHODS The open reading frame ABAYE1518, annotated as a putative Methyl Viologen resistance protein in the genome of s...

Methicillin-resistant Staphylococcus aureus (MRSA) has been listed by the World Health Organization as a priority antibiotic-resistant nosocomial pathogen in urgent need of new antimicrobials [1]. Plasmids are key factor pathology and epidemiology MRSA isolates play important roles their evolution. In our on-going efforts to better understand genetic background molecular from Terengganu, Malays...
