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
This may include a full blood count (FBC), erythrocyte sedimentation rate (ESR), antistreptolysin-O (ASO) titer and throat culture, urinalysis, intradermal tuberculin test, and a chest x-ray. [22] The ESR is typically high, the C-reactive protein elevated, and the blood showing an increase in white blood cells.
Streptolysin O (SLO; slo), is a bacterial toxin that has four protein domains which is known to make the plasma membranes in animal cells permeable. It does this by creating pore complexes within the membrane by first binding a monomer to the cholesterol found in the target membrane and then forming an oligomeric transmembrane pore. [6]
Signs of a preceding streptococcal infection include: recent scarlet fever, raised antistreptolysin O or other streptococcal antibody titre, or positive throat culture. [41] The last revision of 2015 suggested variable diagnostic criteria in low-risk and high-risk populations to avoid overdiagnosis in the first category and underdiagnosis in ...
Toxic shock syndrome (TSS) is a condition caused by bacterial toxins. [1] Symptoms may include fever, rash, skin peeling, and low blood pressure. [1] There may also be symptoms related to the specific underlying infection such as mastitis, osteomyelitis, necrotising fasciitis, or pneumonia.
Streptolysin O An exotoxin, one of the bases of the organism's beta-hemolytic property, streptolysin O causes an immune response and detection of antibodies to it; antistreptolysin O (ASO) can be clinically used to confirm a recent infection. It is damaged by oxygen.
Treatment-emergent central sleep apnea (TECSA), also known as complex sleep apnea, is a type of sleep apnea that typically develops when a patient starts CPAP therapy for OSA. This can occur when ...
Serologic testing seeks evidence of the antibodies that the body produces against the streptococcal infection, including antistreptolysin-O and antideoxyribonuclease B. It takes the body 2–3 weeks to make these antibodies, so this type of testing is not useful for diagnosing a current infection.
