Rickettsiales have NOT been found in wild abalone of northern California (though it would seem the sample size has, as yet, been pretty small).
Rickettsiales are strongly SUSPECTED of being the causative agent for Withering Syndrome.
Rickettsiales HAVE been found in CULTURED Red Abalone as far north as Crescent City (a spit and a holler from the Oregon border).

 Rickettsiales - Wikipedia, the free encyclopedia
The Rickettsiales, also called rickettsias, are an order of small proteobacteria.
Some have also speculated that viruses might have developed from them, or from organisms like them.
The Rickettsiales are among the most mysterious groups of Proteobacteria, owing largely to difficulties in cultivating them.

However, the order Rickettsiales, comprising an assemblage commonly referred to as family Rickettsiaceae and a group of the so-called rickettsia-like endosymbionts (RLE group), was suggested to be paraphyletic, with RLEs having diverged after FLAP but before Rickettsiaceae and mitochondria [5].
Bootstrap limits supporting common ancestry of Rickettsiales and mitochondria were 60, 89, and 43% as inferred from the ML (PUZZLE), DM, and MP analyses, respectively (Fig.
The closest relationship between mitochondria and Rickettsiales is unlikely to be owing to long branch attraction artefact [38] in some analyses, given that not only mitochondria and rickettsiae but also several FLAP are characterized by the long branches.

All tree-generating methods support deep branching of the retrieved 16S rDNA sequences, although an unambiguous pattern of the respective branch origins within the Rickettsiales could not be determined based upon the current data set, resulting in the presence of a multifurcation (24).
