    Description / Table of Contents: Summary The fimbriae of the star-forming bacterium Pseudomonas echinoides are monopolar inserted long threads. They are able to attach to the fimbriae of other cells and to contract themselves, irreversibly joining several cells to a stable star-like cluster. In star--mutants the fimbriae have lost their adhesive properties and their contractability. The fimbriae are about 50 Å in diameter and show a fine structure with a periodicity of about 50–80 Å. Cells with active fimbriae adhere to red blood cells, but only with their fimbriated pole. This haemadsorption is inhibited by mannose. The monopolar fimbriae described here are compared with the peritrichous fimbriae of the Enterobacteriaceae.
    Notes: Zusammenfassung Die Fimbrien des sternbildenden Bakteriums Pseudomonas echinoides sind monopolar inserierte lange Fäden, die die Fähigkeit besitzen, sich mit Fimbrien anderer Zellen zu verbinden, sich dann zu kontrahieren und so mehrere Zellen zu Sternen irreversibel zusammenzuheften. Bei stern--Mutanten haben die Fimbrien die Haftfähigkeit und die Kontrahierbarkeit verloren. Der Durchmesser der Fimbrien beträgt etwa 50 Å. Sie weisen eine Querstruktur mit einer Periode von 50–80 Å auf. Zellen mit aktiven Fimbrien heften sich auf Erythrocyten fest, aber nur mit ihrem fimbriierten Pol. Diese Hämadsorption wird durch Mannose verhindert. Die hier beschriebenen monopolaren Fimbrien werden mit den peritrichen der Enterobacteriaceen verglichen.
