Viele, wenn nicht die meisten Bakterienarten konnen in individueller (planktonischer) oder kollektiver Daseinsform existieren. Der Ubergang zum Kollektiv wird meist durch externe Faktoren bewirkt. Schwarme ermoglichen die effektivere Besiedlung neuer

Pathogene Bakterien uberwinden unsere Abwehrmechanismen durch Ausbildung so genannter Virulenzfaktoren. Dabei handelt es sich in der Regel um toxische Proteine, aggressive Enzyme oder tauschende Oberflachenstrukturen. Deren Synthese ist energie- und

The formation of cyanobacterial heterocysts is unique in the prokaryotic world: it is the only irreversible collective process. This terminal differentiation resembles senescence and differentiation in the eukaryotic urkingdom. During their cell cycl
