Exchange of Genetic Material between Salmonella Typhimurium and Escherichia Coli K-12.
OSITIVE results in attempts to hybridize Salmonella strains with Escherichia Ipcoli K-12 were first reported by BARON and his colleagues (BARON, SPILMAN and CAREY 1959; BARON, CAREY and SPILMAN 1959), and we have also observed this phenomenon with a Salmonella typhimurium wild-type strain LT-7 carrying the mutator gene mut (MIYAKE and DEMEREC 1959; MIYAKE 1959, 1960). This paper supplies more d...
متن کاملGenetic transfer of Salmonella typhimurium and Escherichia coli lipopolysaccharide antigens to Escherichia coli K-12.
Escherichia coli K-12 varkappa971 was crossed with a smooth Salmonella typhimurium donor, HfrK6, which transfers early the ilv-linked rfa region determining lipopolysaccharide (LPS) core structure. Two ilv(+) hybrids differing in their response to the LPS-specific phages FO and C21 were then crossed with S. typhimurium HfrK9, which transfers early the rfb gene cluster determining O repeat unit ...

متن کاملComparison of Escherichia coli K-12 outer membrane protease OmpT and Salmonella typhimurium E protein.
The predicted amino acid sequence of OmpT, an Escherichia coli outer membrane protease, was found to be highly homologous to that predicted for the pgtE gene product of Salmonella typhimurium. In this paper, it is shown that pgtE codes for a protein functionally homologous to OmpT as judged by its ability to proteolyze T7 RNA polymerase and to localize in the outer membrane of E. coli.
متن کاملThe genetic homology of Salmonella typhimurium and Escherichia coli.
H Y B R I D S of enteric bacteria have been useful for various purposes which include the mapping of regions of the Salmonella typhimurium chromosome which are larger than transducing fragments but too short for convenient timeof-entry mapping (DEMEREC l964,1965a,b; DEMEREC and OHTA 1964; GLATZER, LABRIE and ARMSTRONG 1966; ARMSTRONG 1967). Hybrids have also been employed to determine the genet...
