Any evidence bacteria can exist within mitochondria in humans?

[B0b-A]

I heard a claim bacteria can exist within human mitochondria, is there any evidence that is true ?.

https://www.google.com/search?q="bacteria+within+[URL="https://www.physicsforums.com/insights/when-did-mitochondria-evolve/"]mitochondria"[/URL] only gets one hit, and the examples given are not human.

A quick pubmed search suggests this has only been found in ticks:

... An intracellular bacterium with the unique ability to enter mitochondria exists in the European vector of Lyme disease, the hard tick Ixodes ricinus.

Thanks Ryan. According to my one hit on Google the tick is not a "unique" case :
the other species mentioned was "spirostomium minus", a single-celled thingy. [ published in 2003 ].

The claim I heard was pathogenic bacteria exist in human mitochondria, (not symbiotic as in the tick) , and that these alleged bacteria are responsible for wide range of diseases.
IMO the source of this claim was very dubious , but I just wanted to check if there was any evidence to support their claim.
