Summary
An acid glycine extract from a singleCampylobacter jejuni strain was used as the antigen in the enzyme immunoassay (EIA). Elevated values indicating the presence of specific IgM and/or IgG antibodies were found in 73% of 52 patients hospitalized for campylobacter infection. A further 6% of the patients who had lower EIA values in paired serum samples showed at least a 20% change in EIA values. The same sera had been studied earlier for agglutinating antibodies using four reference campylobacter strains. 74% of the patients had shown elevated titres and a further 17% four-fold changes of lower titres in paired sera.
Zusammenfassung
Im Enzym-Immunassay (EIA) wurde ein Säure-Glycin-Extrakt von einem einzelnen Stamm vonCampylobacter jejuni als Antigen verwendet. Bei 73% von 52 wegen Campylobacter-Infektionen stationär behandelten Patienten lagen die Antikörperwerte in einem Bereich, der auf Vorhandensein spezifischer IgM- und/oder IgG-Antikörper schließen läßt. Bei weiteren 6% der Patienten wurden niedrigere EIA-Werte gemessen, doch zeigten sich in gepaarten Serumproben Unterschiede in den EIA-Werten von mindestens 20%. Dieselben Seren waren in Voruntersuchungen auf agglutinierende Antikörper mit vier Campylobacter-Referenzstämmen getestet worden. Eindeutige Titererhöhungen fanden sich bei 74% der Patienten; 17% der Patienten wiesen niedrigere Titer auf, doch waren in gepaarten Seren Unterschiede von mindestens vier Verdünnungsstufen festzustellen.
