A variant enterotoxin gene, referred to as sezA+, has been identified. Staphylococcus aureus FRI1106, a staphylococcal enterotoxin type D producer (Sed+), contained HindIII fragments of 3.8 and 9.4 kilobase pairs (kbp) that hybridized in Southern blot analysis to a probe containing only staphylococcal enterotoxin type A structural gene sequences. Presumably, probe A-624 hybridized to the 9.4-kb...

We investigated the involvement of the recently described staphylococcal enterotoxins G and I in toxic shock syndrome. We reexamined Staphylococcus aureus strains isolated from patients with menstrual and nonmenstrual toxic shock syndrome (nine cases) or staphylococcal scarlet fever (three cases). These strains were selected because they produced none of the toxins known to be involved in these...

Drug-resistant staphylococci, particularly Staphylococcus aureus and Staphylococcus epidermidis, are leading causes of hospital-acquired infections. Bacteriophages and their peptidoglycan hydrolytic enzymes (lysins) are currently being explored as alternatives to conventional antibiotics; however, only a limited diversity of staphylococcal phages and their lysins has yet been characterized. Her...

In a rabbit model of wound infection caused by Staphylococcus aureus, 2 x 10(9) PFU of staphylococcal phage prevented abscess formation in rabbits when it was injected simultaneously with S. aureus (8 x 10(7) CFU) into the same subcutaneous site. Phage multiplied in the tissues. Phages might be a valuable prophylaxis against staphylococcal infection.

Genes encoding staphylococcal enterotoxins (sea to see, seg, and seh), toxic shock syndrome toxin 1 (tst), and exfoliative toxins (eta and etb) were not detected in a large panel of 48 Staphylococcus sciuri group isolates tested. This strongly suggests that production of the staphylococcal exotoxins by these bacteria is highly unlikely.

A chromatofocusing procedure for the purification of staphylococcal enterotoxin D was developed. The purification included the removal of the toxic protein from culture supernatant fluids of Staphylococcus aureus 1151m by batch adsorption with CG-50 resin, chromatofocusing on Polybuffer Exchanger 94, and gel permeation chromatography on Sephacryl S-200. The purity of the staphylococcal enteroto...

Background: T cell activation is discussed as an important factor in the pathogenesis of psoriasis. Recently, a lot of attention has been paid to the role of superantigens in T cell activation in the pathogenesis of psoriasis. In this study, the role of staphylococcal superantigens in the pathogenesis of psoriasis with identification of staphylococcal toxin levels in the skin lesions of p...

977 T HE STAPHYLOCOCCUS problem has been placed high on the agenda of the Public Health Service for this year. Last year it was Asian flu vaccine. The year before it was poliomyelitis vaccine. This year it is the problem of hospital-acquired staphylococens infection. It is pleasing to me to see the position pediatricians have taken as one of the first national organizations to realize the impor...

All the forms of staphylococcal infections require cooperation among microbiologists, immunologists and clinicians. In case of any acute staphylococcus process, the curative tactics is based on an effective chemotherapy sometimes completed by a radical surgical intervention. In case of chronic forms, however, the antibiotics therapy is considered to be problematic. It is the specific immunother...

Staphylococcal foodborne illness, caused by the ingestion of contaminated foods induced Staphylococcus aureus enterotoxins, is one most recurrent diseases worldwide. Food handlers working in food-service establishments who carry enterotoxigenic isolates represent a reservoir for potential contamination leading to staphylococcal food intoxication. The aim this research was investigate prevalence...
