| Abstrakt: | DPANN archaea are a diverse group of microorganisms that are thought to rely on an ectosymbiotic lifestyle; however, the cell biology of these cell-cell interactions remains largely unknown. We applied live-cell imaging and cryo-electron tomography to the DPANN archaeon Nanobdella aerobiophila and its host, revealing two distinct life cycle stages. Free cells possess archaella and are motile. Ectobiotic cells are intimately linked with the host through an elaborate attachment organelle. Our data suggest that free cells may actively seek a new host, while the ectobiotic state is adapted to mediate intricate interaction with the host. (© The Author(s) [2024].
