The antivirulent Staphylococcal sRNA SprC regulates CzrB efflux pump to adapt its response to zinc toxicity

SprC expression during bacterial growth. (A) Relative quantification of SprC expression was determined by northern blot using tmRNA as an internal loading control. The data presented are the mean of three independent biological replicates. (B) One representative northern blot analysis of SprC expression during bacterial growth. Cells were cultured in BHI at 37°C, and total RNA was extracted every 30 min until 5 h of growth, then every hour.
