Staphylococcal superantigen(SAg)toxins are the most notable virulence factors associated with Staphylococcus aureus,which is a pathogen associated with serious community and hospital acquired infections in humans and ...
This study aimed to investigate the carriage of Streptococcus pyogenes in population vulnerable to scarlet fever and to compare their genotypic characterization between different age groups. Pharyngeal swabs were coll...
Microbial stimulation in early childhood may be necessary for proper maturation of the immune system. Infants colonized with Staphylococcus aureus have low risk of developing food allergy. Neonatal exposure to staphyl...
Objective To explore the relationship between superantigen and M protein gene(emm)-types genes of Group A Streptococcus pyogenes(GAS)isolated from patients with scarlet fever in Beijing from May 2012 to July 2013.Meth...

We have investigated the response of T cells to staphylococcal enterotoxin A (SEA) injections in vivo. We found that a single injection of SEA with an optimal dose of 10μg increased the expression of both CD4 and C...
In order to gain insight into a possible association between chronic sinusitis and asthma, 85 patients with sinusitis and asthma underwent functional endoscopic sinus surgical treatment and serum antibodies and cytoki...
Summary: The anti-tumor effect and mechanism of SEA-Fab' coupled protein on gastric tumor was studied. The target cell Walke-256 was treated with SEA-Fab' synthesized chemically or SEA respectively for 24 h, 36 h o...
