[Detection of Staphylococcus aureus and Staphylococcus epidermis species specific antigens and antibodies to alpha-toxin in the blood of patients with pneumonia].
Test systems for indirect hemagglutination (IHA) test for detection of S. aureus and S. epidermidis teichoic acids and S. aureus alpha-toxin in patients' sera have been developed on the basis of immunoglobulins isolated from monospecific sera. Test system for IHA test for detection of antitoxin in donor and patients' sera has been created on the basis of highly purified alpha-toxin. Thirty donor sera and 61 sera from patients with pneumonia were analyzed. Low antibody levels in the patients may be due to the fact that the sera were collected during the first days of disease. Group of patients with high content of staphylococcal antigens and antitoxin in the blood was particularly interesting. These patients developed severe pneumonia, among whose etiological agents were S. aureus and S. epidermidis. Diagnostic analysis of patients' sera by IHA test for detection of staphylococcal antigens was more effective, accurate, and rapid in comparison with the bacteriological method; moreover, it confirmed the significance of staphylococci in the pathogenesis of pneumonia.
