Mercury resistance in Yersinia enterocolitica.


First isolation of a mercury-resistant strain of Yersinia enterocolitica is reported. This strain, named 138-A14, is resistant to mercuric chloride and merbromin, but sensitive to phenylmercuric borate and sodium merthiolate. The mercury resistance of 138-A14 is not transferable spontaneously to Escherichia coli K12 by conjugation.
