Formatted abstract Candidatus Midichloria mitochondrii (M. mitochondrii) belongs to a novel clade
of bacteria within the order Rickettsiales. Recent PCR-based screening studies
indicate that it is present in a number of blood-sucking arthropods, as well as the
blood of some vertebrates. Its medical and veterinary significance remains to be
determined. Electron microscopic examinations of M. mitochondrii have thus far
been conducted on two infected tick species. Remarkably, the bacterium was found
in abundance within the mitochondria of the ovarian cells of each tick species. This
makes it the only characterized bacterium able to invade the mitochondria of
any multicellular organism. To examine whether mitochondrial invasion is a
consistent characteristic of M. mitochondrii, we examined two tick species found
in Eastern Australia. One of these species, Ixodes holocyclus, was infected with two
M. mitochondrii strains; however, no bacteria were seen in the mitochondria.
Comparative studies involving these strains may shed light on the unique
phenomenon of mitochondrial invasion.
