Isolation of an R- M+ mutant of Yersinia enterocolitica serotype O:8 and its application in construction of rough mutants utilizing mini-Tn5 derivatives and lipopolysaccharide-specific phage.

Abstract excerpt

A generally applicable procedure was used to isolate a spontaneous restriction-deficient mutant of Yersinia enterocolitica serotype O:8. Transposition frequency in the mutant strain 8081-res was approximately 6.7 x 10(-6) per recipient, while it was practically zero in the wild-type strain 8081-c...
