The 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...
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 کاملSalmonella typhimurium intercepts Escherichia coli signaling to enhance antibiotic tolerance.
Bacterial communication plays an important role in many population-based phenotypes and interspecies interactions, including those in host environments. These interspecies interactions may prove critical to some infectious diseases, and it follows that communication between pathogenic bacteria and commensal bacteria is a subject of growing interest. Recent studies have shown that Escherichia co...
متن کاملLipids of Salmonella typhimurium and Escherichia coli: structure and metabolism.
The nature and quantity of the phospholipids of Salmonella typhimurium and Escherichia coli K-12 have been examined. The main classes of phospholipids, phosphatidylethanolamine, phosphatidylglycerol, and cardiolipin have been completely characterized. Four minor compounds have been detected: phosphatidylserine, phosphatidic acid, and two partially characterized lipids. The phospholipid composit...
متن کاملAmino-terminal sequences of indoleglycerol phosphate synthetase of Escherichia coli and Salmonella typhimurium.
The partial sequences of the first 40 residues of indoleglycerol phosphate synthetase of Escherichia coli and Salmonella typhimurium were determined, and three amino acid differences were observed among the 38 residues compared.
