[Compared survival of "Escherichia coli" and "Salmonella typhi-murium" in cold water (author's transl)]

The survival rates of Escherichia coli and Salmonella typhi-murium in water are studied at 4, 10 and 20 degrees C and pH 6 and 8, either separately or in mixed culture at four different ratios. S. typhi-murium's survival rate is enhanced at pH 6 and low water temperature. The value of traditional microbiological indicators in assessed in cold water conditions.
