Elusimicrobiota

Elusimicrobiota is a genus of bacteria belonging to the phylum Elusimicrobia. This phylum was previously known as the TM6 phylum. Members of Elusimicrobiota are characterized by their obligate intracellular parasitic lifestyle, meaning they can only survive and reproduce within the cells of a host organism. Their discovery and characterization have significantly expanded our understanding of microbial diversity and host-microbe interactions.

These bacteria have been identified in various host organisms, including protists and other microorganisms. The host-associated nature of Elusimicrobiota suggests a long co-evolutionary history with their hosts. Research into their genomes has revealed unique metabolic pathways and a reduced genome size, consistent with their parasitic existence. Their reliance on host resources likely dictates their limited metabolic capabilities outside of their host.

The study of Elusimicrobiota is ongoing, with researchers working to understand their precise mechanisms of host infection, their role in host physiology, and their evolutionary relationships with other microbial groups. Advances in sequencing technologies have been crucial in identifying and analyzing these previously unculturable bacteria. Further research aims to shed light on the potential ecological significance and broader implications of these fascinating intracellular symbionts.
