Exposure to pH 1 or 2 buffers or acidic gastric contents resulted in the killing of vancomycin-resistantEnterococcus sp.,Klebsiella pneumoniae ,Staphylococcus aureus , andCandida glabrata but notClostridium difficile spores. Nitrite enhanced killing under acidic conditions, but significant killing ofC. difficile spores required nitrite concentrations above usual physiological levels.
