The "Other" Rickettsiales: an Overview of the Family "Candidatus Midichloriaceae".

ABSTRACT: The family "Candidatus Midichloriaceae" constitutes the most diverse but least studied lineage within the important order of intracellular bacteria Rickettsiales. "Candidatus Midichloriaceae" endosymbionts are found in many hosts, including terrestrial arthropods, aquatic invertebrates, and protists. Representatives of the family are not documented to be pathogenic, but some are associated with diseased fish or corals. Different genera display a range of unusual features, such as full sets of flagellar genes without visible flagella or the ability to invade host mitochondria. Since studies on "Ca. Midichloriaceae" tend to focus on the host, the family is rarely addressed as a unit, and we therefore lack a coherent picture of its diversity. Here, we provide four
