  • Title: Antigen release from Thermoactinomyces vulgaris by lysozyme treatment.

    Abstract:
    Lysozyme treatment was used to release antigenic material from Thermoactinomyces vulgaris, one of the microbes associated with farmer's lung. Lysozyme caused degradation of the murein layer visualized as changes and disappearance of the bacterial morphology in scanning electron microscopy. Enrichment of different antigenic components in the lysozyme extract and in the cell residue, respectively, was detected by immunoprecipitation. When lysozyme extract and cell residue antigens were used in enzyme-linked immunosorbent assay to test sera of farmer's lung patients and control persons, it became evident that there was no significant difference between the reactions against the two antigens. However, a number of sera reacted preferentially against one or the other of the two antigens.
