title: [Characteristics of the cytolysin of Legionella pneumophila].
abstract: A thermolabile cytolysin was purified from liquid culture of L. pneumophila. Its homogenicity was determined by the Ouchterlony double immunodiffusion and SDS-electrophoresis in polyacrylamide gel. The molecular weight of cytolysin was ca. 37 kDa. Analysis of amino acid composition revealed a high proportion of aromatic, dicarbonic amino acids, and methionine. The minimal cytolytic concentration for CHO cells and erythrocytes was ca. 1 microgram/ml: Purified cytolysin in doses of 10-60 micrograms caused haemorrhage and necrosis when injected i. c. into guinea pigs.
