Evidence for the existence of two molecular species of exfoliative toxin (ET) synthesized by phage group II Staphylococcus aureus under chromosomal and plasmid control is presented. Serological evidence that these molecular species of toxin are distinct from each other is given. The plasmid-controlled toxin was synthesized along with the chromosomally(More)
The ability of phage group II staphylococcal strain UT 0101 to produce exfoliative toxin and bacteriocin could be eliminated at a high frequency after growth at high temperatures or in the presence of ethidium bromide or sodium dodecyl sulfate. Extrachromosomal deoxyribonucleic acid, associated with the genes for exfoliative toxin and bacteriocin(More)
The scalded skin syndrome has been associated with phage group II staphylococci. The clinical manifestations of scalded skin syndrome, Ritter's disease, scarlatiniform erythema, and localized bullous impetigo, are due to the production of an extracellular protein, designated exfoliative toxin. Phage group II staphylococci can also produce an extracellular(More)
In previous studies, we have shown that a 27-megadalton plasmid (pRW002) in Staphylococcus aureus contains genetic determinants for exfoliative toxin B (ET B) and bacteriocin (Bac R1) synthesis and Bac R1 resistance. Attempts to transform or transduce this plasmid to S. aureus or Bacillus subtilis recipients were not successful. However, genetic transfer of(More)
Complement fixation (CF), immunofluorescence, and agar gel double-diffusion tests were used to demonstrate an antigenic relationship between rat tissues and Mycoplasma arthritidis. Rabbit antisera against six strains of M. arthritidis exhibited positive reactions in the CF test with an ethyl alcohol-saline extract of rat muscle, whereas only 6 of 18(More)
Previous studies established that Mycoplasma arthritidis produces a soluble T cell mitogen (MAM), and that response of murine T cells to MAM is genetically restricted. MAM appeared predominantly in the supernatants of senescent cultures, but was not extracted in significant amounts from whole cells. A quantitative assay of MAM activity was devised. MAM(More)
The Smith diffuse variant and the wound mucoid strain of Staphylococcus aureus were shown to exhibit serologically distinct capsules. The Welwood and K-6 strains of S. aureus were tested to determine their capsular types. Both Welwood and K-6 were found to be representative of the Smith capsular type. An additional 13 isolates of S. aureus from mice were(More)
Staphylococcal scalded skin syndrome, associated with exfoliative toxin produced by phage group II Staphylococcus aureus, has recently been reported in an adult receiving immunosuppressive therapy. To determine the effect of immunosuppression on the development of the staphylococcal scalded skin syndrome, experimental animals were treated with prednisolone,(More)
