The measurement of anti-streptokinase antibodies can distinguish the patients who may benefit from streptokinase and those who should be treated with some other thrombolytic regimen. Neutralising titration test is a commonly used classical assay for measuring anti-streptokinase antibodies and in this assay the ability of anti-streptokinase antibodies in patients' sera in preventing the lytic ef...
Streptococcus pyogenes (group A streptococcus, GAS) secretes streptokinase, a potent plasminogen activating protein. Among GAS isolates, streptokinase gene sequences (ska) are polymorphic and can be grouped into two distinct sequence clusters (termed cluster type-1 and cluster type-2) with cluster type-2 being further divided into sub-clusters type-2a and type-2b. In this study, far-UV circular...
background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...
introduction: group a beta-hemolytic streptococcus (gabhs) can induce pandas (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). gabhs is the most important and common bacterial cause of acute pharyngitis in iranian children. we studied the role of gabhs (anti-streptococcal antibodies) in suspected cases of pandas in a cross sectional studies. methods: acr...
The administration of high-dose clindamycin (CLI) along with penicillin is recommended for the treatment of streptococcal toxic shock syndrome. However, the prevalence of CLI-resistant Streptococcus pyogenes strains is increasing worldwide, and the effect of CLI on CLI-resistant S. pyogenes strains remains unknown. We aimed to evaluate the effect of CLI on the in vitro production of three major...
Introduction: Group A Beta-Hemolytic Streptococcus (GABHS) can induce PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). GABHS is the most important and common bacterial cause of acute pharyngitis in Iranian children. We studied the role of GABHS (anti-streptococcal antibodies) in suspected cases of PANDAS in a cross sectional studies. Method...

Streptococcus pyogenes produces several extracellular proteins, including streptococcal erythrogenic toxin B (SPE B), also known as streptococcal pyrogenic exotoxin B and streptococcal proteinase. Several reports suggest that SPE B contributes to the virulence associated with S. pyogenes; however, little is known about its regulation. Nucleotide sequence data revealed the presence, upstream of ...
To determine the distribution of antibodies to streptokinase that might be anticipated in patients requiring treatment with streptokinase, specific anti-streptokinase antibody titres were determined in a group of subjects from the general population and in a group of patients presenting with acute myocardial infarction. Enzyme-linked immunosorbent assays were developed to measure specific anti-...
