Recombination-deficient mutant of Streptococcus faecalis.

An ultraviolet radiation-sensitive derivative of Streptococcus faecalis strain JH2-2 was isolated and found to be deficient in recombination, using a plasmid-plasmid recombination system. The strain was sensitive to chemical agents which interact with deoxyribonucleic acid and also underwent deoxyribonucleic acid degradation after ultraviolet irradiation. Thus, the mutant has properties similar...

Microbiological assay for thymine using a mutant of Streptococcus faecalis.

Doctor, V. M. (University of Texas, Houston). Microbiological assay for thymine using a mutant of Streptococcus faecalis. J. Bacteriol. 84:17-22. 1962.-A rapid microbiological assay procedure for the determination of thymine was devised. The test organism, Streptococcus faecalis Akt, a mutant of S. faecalis ATCC 8043, gives one-half the maximal growth response to 1.6 mug of thymine (assay range...

Phospholipids of Streptococcus faecalis.

Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...

aureus, and Streptococcus faecalis

SYNOPSIS The incidence of trimethoprim resistance in coliforms and multiresistant strains of Staphylococcus aureus isolated in Bristol from 1970 to 1972 is low-2-3 and 1 0% respectively. The resistance is probably intrinsic; there is no evidence that it is R-factor or plasmid mediated. A single mechanism that confers resistance to both trimethoprim and sulphamethoxazole has not been detected. N...
