Summary: | Abstract DPANN Archaea are a diverse group typically characterised by small cells and reduced genomes. To date, all cultivated DPANN Archaea are ectosymbionts that require direct cell contact with a host archaeal species for proliferation. However, the dynamics of DPANN – host interactions and the impacts of these interactions on host species are poorly understood. Here, we show that one DPANN archaeon ( Candidatus Nanohaloarchaeum antarcticus) engages in parasitic interactions with its host ( Halorubrum lacusprofundi ) that result in host cell lysis. Our data also suggest that these interactions involve invasion of the host cell by the nanohaloarchaeon. This is the first reported instance of such a predatory-like lifestyle amongst Archaea and indicates that some DPANN Archaea may interact with host populations in a manner similar to viruses.
