Salmon poisoning disease (SPD) is an often fatal condition, occurring when a dog eats raw salmon that is infected with the Neorickettsia helminthoeca parasite. This disease typically begins in the tissues of the small intestine, where it causes hemorrhaging. It gradually becomes systemic, invading the entire body.
The signs and symptoms of SPD include the following:
Dogs contract the Neorickettsia helminthoeca parasite when they consume raw fish, including raw salmon, trout, and other fish that contain the N. helminthoeca organisms, like the trematode vector.
To diagnose SPD, your veterinarian will need to rule out other conditions that are known to cause similar symptoms, including:
Once these alternate conditions have been ruled out, your doctor will collect fluid from a swollen lymph node to test for Rickettsial bodies. This can be done using the Giemsa stain technique, which stains the DNA of parasites, making them visible under microscope.
Your doctor will also perform an examination of the feces to discover whether the organism Nanophyetus salmincola has laid eggs in the feces, which will also confirm a diagnosis of SPD. Other findings may include changes in the lymph tissue, which may show yellowish tissue in the lymph node, and blood within the intestinal contents.
