Abstract
The antigenic specificity of the human immune response during legionellosis was studied. Twenty-two sera obtained from 12 individuals were studied using the Western-blot technique with antigens from various legionella. In five of six patients, the reactivity of their sera obtained at different times during legionellosis was qualitatively constant. In one patient, a new IgG antibody to a 50 Kdal bacterial antigen appeared between the 14th and 22nd day after infection. In every patient, the IgG and IgM responses differed. When the patient's serum was reacted with antigen prepared from the isolate obtained from that patient or from a closely related isolate, the antibody response appeared to be directed against broad antigenic bands. Die Antigen-Spezifität der menschlichen Immunantwort während der Legionella-Erkrankung wurde untersucht. Mittels Western-blot-Technik unter Verwendung von Antigenen verschiedener Legionella-Stämme wurden 22 Seren von 12 Patienten untersucht. Bei fünf von sechs Patienten war eine qualitativ gleichbleibende Reaktivität der zu verschiedenen Zeitpunkten während der Legionellose entnommenen Seren zu beobachten. Bei einem Patienten erschien zwischen dem 14. und 22. Tag nach der Infektion ein neuer IgG-Antikörper gegen ein bakterielles Antigen von 50 Kdal. Bei jedem Patienten war die IgG- und IgM-Antwort verschieden. Wenn das Patientenserum mit einer Antigen-Präparation aus dem von diesem Patienten isolierten Stamm oder aus einem nahe verwandten Isolat getestet wurde, zeigte sich eine gegen breite Anti-genbande gerichtete Antikörperantwort.Keywords
