title: [Contributions to the study of properdin. 4. Report: in vitro model study on the effect of cattle properdin on Escherichia coli].
abstract: Light and electron microscopy were used in model experiments to study a high-titre "properdine-system" culture and its action in terms of altering E. coli bacteria. The reaction was altogether strongly predominated by the three following phases of lysis. 1. Onset of massive agglutination after few minutes; 2. Decomposition of bacterial structure by lysis after ten to twelve hours; 3. Terminal phase of lysis after two to three days (amorphous detritus).
