streptolysin O

04/01/2021 - "Factors that improved model fit were higher platelet and lower white blood cell counts, elevated anti-streptolysin O and a history of preceding infection. "
01/08/2013 - "Furthermore, the innovative construction of an isogenic strain expressing a functionally inactive toxin and its use in infection and opsonophagocytosis experiments allowed us to investigate the mechanism by which streptolysin O mediates protection against group A Streptococcus. "

04/01/2005 - "This report documents treatment and imaging of a 13-year-old boy who had an episode of right-sided orbital myositis following streptococcal pharyngitis with anti-streptolysin-o (ASO) titer elevation to 1,188 IU/ml. Clinically, this patient demonstrated acute onset of marked restriction and mild under-action of the lateral rectus muscle of the right eye. "
04/01/2006 - "Isolation of beta hemolytic streptococci from throat cultures and their identification as GAS in the laboratory, clinches the microbiological diagnosis while demonstration of a 'significant rise' in antibody titers such as Anti-streptolysin O and Anti-deoxyribonuclease B differentiates it from a group A streptococcal carrier state or pharyngitis of a viral etiology. "
11/01/2021 - "Streptolysin O (SLO) is produced by common hemolytic streptococci that cause a wide range of diseases from pharyngitis to life-threatening necrotizing fasciitis and toxic shock syndrome. "
01/01/1974 - "The immune response to this somatic antigen was measured in 159 children with culture-proved group A streptococcal pharyngitis and was compared with that to two extracellular antigens of the Group A streptococcus: streptolysin O and streptococcal DNase B. "

03/01/2009 - "During the follow-up period, there was improvement in Physician's Global Assessment, number of patients with arthralgia, tender and swollen joints, erythrocyte sedimentation rate, anti-streptolysin O, and anti-DNAse B antibody titers. "
09/01/2013 - "A 39 year-old patient consulted his family doctor due to migratory polyarthralgia, with C-reactive protein 7.99mg/dl, ESR 89mm and normal anti-streptolysin O (ASO). "
08/01/2023 - "Results In this study, no statistical difference was found between the presence of MEFV gene mutations, carditis, high anti-streptolysin-O antibody (ASO) levels, and the groups with monoarthritis, polyarthritis, and polyarthralgia (p >0.05). "
03/16/2020 - "Revised Jones criteria met included significantly elevated streptolysin O antibody and anti-DNase B, carditis, arthralgia, fever, and elevated inflammatory markers. "
