ANTIESTREPTOLISINA O ASO PDF

Anti-streptolysin O ASO or ASLO is the antibody made against streptolysin O , an immunogenic, oxygen-labile streptococcal hemolytic exotoxin produced by most strains of group A and many strains of groups C and G Streptococcus bacteria. The "O" in the name stands for oxygen-labile ; the other related toxin being oxygen-stable streptolysin-S. The main function of streptolysin O is to cause hemolysis the breaking open of red blood cells — in particular, beta-hemolysis. Increased levels of ASO titre in the blood could cause damage to the heart and joints.

Antistreptolysin O titer profile in acute rheumatic fever diagnosis. METHODS: we investigated 78 patients with ARF at onset and follow-up, 22 with isolated chorea at onset, 45 with recurrent oropharyngeal tonsillitis, and 23 with recent flare of juvenile idiopathic arthritis. Baseline levels were observed afterwards in patients under regular penicillin prophylaxis.
