Ovine-associated Staphylococcus aureus protein with immunochemical similarity to toxic shock syndrome toxin 1.
نویسندگان
چکیده
A toxic shock syndrome toxin 1 (TSST-1) antibody-binding protein produced by an ovine-associated strain of Staphylococcus aureus was examined. The protein showed total identity to TSST-1 by immunodiffusion analysis. Western blots (immunoblots) of proteins separated by isoelectric focusing revealed that the TSST-1 antibody-binding protein had a pI of 8.6 rather than 7.0, the pI of standard TSST-1.

Identification of Toxic Shock Syndrome Toxin-1 (TSST-1) gene in Staphylococcus aureus isolated from bovine mastitis milk
Staphylococcus aureus is a major causative pathogen of clinical and subclinical mastitis of dairy domestic ruminants. This agent produces a variety of extracellular toxins and virulence factors including Toxic Shock Syndrome Toxin-1 (TSST-1) which is the major cause of Toxic Shock Syndrome (TSS). In this study 58 S. aureus isolates obtained from 9 dairy herds in East and West Azerbaijan provinc...

A toxic shock syndrome toxin (TSST) variant with an isoelectric point (pI) of 8.6 produced by an ovine-associated Staphylococcus aureus strain was described previously. Analysis of additional strains associated with sheep, goats, cows, and humans by isoelectric focusing with immunoblotting using monoclonal antibodies revealed that all 18 strains associated with sheep and all 12 strains associat...
متن کاملInvestigation by syringe method of effect of tampons on production in vitro of toxic shock syndrome toxin 1 by Staphylococcus aureus.
A syringe method was designed to test the effect of tampons on the growth of three toxic shock syndrome-associated strains of Staphylococcus aureus and their in vitro production of toxic shock syndrome toxin 1 (TSST-1) under different conditions. Various amounts of TSST-1 were recovered from different tampons inoculated with these strains. Generally, the addition of 10% porcine blood to the gro...
متن کاملSpontaneous occurrence of Staphylococcus aureus mutants with different pigmentation and ability to produce toxic shock syndrome toxin 1.
Spontaneous mutants that have pigmentation different than that of their parents were isolated from three Staphylococcus aureus strains associated with toxic shock syndrome. These mutants produced toxic shock syndrome toxin 1 in amounts varying from less than 0.05 to greater than 25 times that produced by the parents. The occurrence of nonpigmented variants may be overlooked if only one isolate ...
متن کاملPrevalence of Antibody to Toxic Shock Syndrome Toxin-1 in Burn Patients
BACKGROUND Burn wounds lack normal barriers that protect against pathogenic bacteria, and burn patients are easily colonized and infected by Staphylococcus aureus. Toxic shock syndrome (TSS) is a rare but fatal disease caused by S. aureus. A lack of detectable antibodies to TSS toxin-1 (TSST-1) in serum indicates susceptibility to TSS. METHODS A total of 207 patients (169 men and 38 women; me...
