A transposon in Streptococcus faecalis with fertility properties

Homology of a transferable tetracycline resistance determinant of Clostridium difficile with Streptococcus (Enterococcus) faecalis transposon Tn916.

In several tetracycline-resistant (Tetr) Clostridium difficile strains, homology with the Tn916 part of plasmid pAM120 DNA was observed. This 15-kilobase transposon, carrying a Tetr determinant, was originally found in Streptococcus (Enterococcus) faecalis. Hybridization experiments revealed that at least six of seven HincII fragments of Tn916, representing greater than 95% of its length, showe...

Conjugal transfer of transposon Tn916 from Streptococcus faecalis to Mycoplasma hominis.

Transposon Tn916 was transferred from Streptococcus faecalis to Mycoplasma hominis by a mating process resembling conjugation with a frequency of 10(-6) to 10(-7). Tn916 was inserted into the mycoplasmal chromosome in single and multiple copies.

Hydroxylysine metabolism in Streptococcus faecalis.

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...

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...
