Salmon poisoning disease
(重定向自Salmon poisoning)
Salmon poisoning disease (SPD) is a fatal disease of dogs and other canids caused by a rickettsial parasite, Neorickettsia helminthoeca. It results from eating raw salmon, trout, or salamander and is common in the Pacific Northwest. These fish and amphibians are infected with the larvae of a fluke, Nanophyetus salmincola through an intermediate host, the snail Oxytrema plicifer. The larvae attaches to the intestine of the dog and the rickettsial parasites are released, causing severe gastrointestinal disease and systemic infection.
