(Submitter supplied) Antibiotic resistance (AR) is one of the greatest threats to global health and is associated with higher treatment costs, longer hospital stays, and increased mortality. Current gold standard antibiotic susceptibility tests (AST) are dependent on organism growth rates resulting in prolonged diagnostic answers for slow growing organisms. Changes in the cellular transcriptome can be instantaneous in the presence of stressors such as antibiotic pressure. more...

(Submitter supplied) Cultures of Y. pestis Kimberley53 virulent strain were exposed to different concentrations of ciprofloxacin (including 0.016 µg/ml representing the strains' MIC value) for various time periods. Total RNA samples were extructed and used for cRNA synthesis and labelling (using Cy3-CTP for the treated samples and Cy5-CTP for the non-treated sample in one biological experiment and dye swap for the 2nd replicate of independent biological experiment). more...

(Submitter supplied) Yersinia pseudotuberculosis is a Gram-negative bacterium capable of causing gastrointestinal infection and is closely related to the highly virulent plague bacillus Yersinia pestis. Infection by both species are currently treatable with antibiotics such as ciprofloxacin, a quinolone-class drug of major clinical importance in the treatment of many other infections. Our current understanding of the mechanism of action of ciprofloxacin is that it inhibits DNA replication by targeting DNA gyrase, and that resistance is primarily due to mutation at this target site, along with generic efflux and detoxification strategies. more...
