background: staphylococcus aureus, the major virulence factor of hospital and community acquired infections, secretes numerous exotoxins (super antigens), which may affect immunological and inflammatory status in psoriatic skin lesion. objectives: this study is designed to compare the s. aureus super antigens level in sera of psoriatic patients with normal cases (nevus). patients and methods: a...

results in total, 80 food samples suspected of seb contamination were assessed using the two methods. fifty-four samples were contaminated based on the pcr technique and twenty-six of those were confirmed using the strip assay. conclusions the sensitivity of the sandwich method was approximately 10 ng/ml and that of the competitive method was approximately 250 ng/ml. in the lfd, a highly specif...

background rheumatoid arthritis (ra) is the most common chronic inflammatory disease. the staphylococcal superantigens are considered as the causative agent of ra disease. objectives this study aimed to assess the presence of staphylococcal enterotoxin d in synovial fluid and blood of patients with ra. patients and methods a total of 120 blood and sf samples of patients with ra were studied. ba...

septic arthritis with polyarticular presentation is an uncommon clinical entity. a case of complicated staphylococcal infection with purulent and reactive polyarthritis, osteomyelitis, cutaneous and pleuropericardial involvement as well as transient blindness is presented here.

conclusions prevalence of fbe and aap was significantly different from similar studies, yet frequency of bhp was in accordance with other studies. prevalence of icaa and is256 was not significantly different from some studies while a significant difference was observed when results were compared with some other studies. results of the 59 s. epidermidis, fbe was found in 89.8%, while aap and bhp...

Methicillin-resistant Staphylococcus aureus (MRSA) is a challenging infectious agent worldwide. The ever growing antibiotic resistance has made the researchers to look for new anti-staphylococcal agents. Autolysins are staphylococcal enzymes that lyse bacterial cell wall for cell division. Autolysins can be used as novel enzybiotics (enzymes have antibiotic effects) for staphylococcal ...

Broth culture filtrates from several strains of Staphylococcus aureus produce fever when injected intravenously into normal or previously sensitized rabbits.' This response appears to depend upon a naturally acquired state of delayed hypersensitivity, which may be increased with specific infection.2 Rabbits made unreactive (tolerant) to filtrate from one staphylococcal strain were tolerant to f...

BACKGROUND About 20 different types of staphylococcal enterotoxins are produced by Staphylococcus aureus, in which type A is more common in food poisoning syndrome. Also staphylococcal enterotoxin A superantigen is a potent inducer of cytotoxic T lymphocyte activity and cytokine production and could stimulate T cells containing T-cell receptor beta chain domains when binding to major histocompa...

Rates of hospital-acquired staphylococcal infection increased throughout the 1990s; however, information is limited on trends in community-onset staphylococcal disease in the United Kingdom. We used Hospital Episode Statistics to describe trends in hospital admissions for community-onset staphylococcal disease and national general practice data to describe trends in community prescribing for st...
