Other examples
of rickettsial organisms are Riskettsia rickettsi, which causes Rocky Mountain Spotted Fever and Ehrlichia risticii, which causes Potomac Fever in horses.
In addition, there is
a rickettsial organism known as Wolbachia that is a parasite of the heartworm.
Ehrlichiosis is caused by
the rickettsial organism Ehrlichia canis.
If a dog ingests raw fish containing the flukes that are infected with
the rickettsial organism, salmon poisoning will occur.
Salmon poisoning is caused by
a rickettsial organism (a very small type of bacteria) that can be found within flukes (parasitic flatworms) infecting the tissues of wild fish found in coastal streams of the Pacific Northwest.
These samples are sent off to a laboratory for analysis, and the pathologist may be able to visualize the presence of
the rickettsial organism within the lymphoid cells.
Systemic illness in the dog occurs if the fluke is infected with
a rickettsial organism, Neorickettsia helminthoeca.
The rickettsial organism Neorickettsia helmonthoeca is embedded within the fluke, Nanophyetus salmincola, which is embedded within raw fish.
The rickettsial organisms then hematogenously spread to the liver, lungs, brain, and lymphoid tissues causing necrosis, hemorrhage, and hyperplasia.
