(Submitter supplied) Methicillin resistant Staphylococcus aureus (MRSA) infection is becoming refractory to existing antibiotic therapy owing to the inherent ability of S. aureus to develop rapid resistance and is considered a major threat to public health. We found that a natural isolate of Bacillus pumilus from the Columbia River Estuary produces a strong anti-MRSA compound, amicoumacin A. As amicoumacin A has been reported to exhibit anti-microbial, anti-inflammatory, and anti-ulcer activities, we sought to uncover its mechanism of action. more...

(Submitter supplied) Genome-wide transcriptional profiling studies of the growth of bacteria with antimicrobial agents often reveals aspects of the drug-specific protective bacterial response. Fusidic acid is a steroid antimicrobial that inhibits protein synthesis by interfering with the release of elongation factor G (EF-G) after it has functioned in the translocation step. Two hundred and seventy two genes were both up- and down-regulated in a fusidic acid-susceptible strain of Staphylococcus aureus following challenge with 2 mg/L-1 fusidic acid for 15 min. more...

(Submitter supplied) To determine the role of the second gene in the vra operon (vraT) in the stress response to oxacillin, we compared the oxacillin induction profiles in a vraT deletion strain to that of a vraSR mutant in a USA300 MRSA strain background.
