Abstract | The presence of the etiologic agent of "salmon poisoning" disease, Neorickettsia helminthoeca, was demonstrated in eggs of the trematode vector, Nanophyetus salmincola. Three dogs were given 100,000 and one dog 82,000 ground fluke eggs by intraperitoneal injection. The four animals developed "salmon poisoning" disease and died. One of these dogs had been given 100,000 intact eggs previously; this inoculum did not produce the disease. Two dogs that received either intact or ground adult flukes intraperitoneally also died from "salmon poisoning" disease. Noninjected control dogs remained healthy in all instances. Lymph nodes removed from a dog that had been injected with 82,000 ground eggs and had died from the disease were injected intraperitoneally into a susceptible dog. After this dog developed signs of "salmon poisoning" disease, it was given antibiotic therapy and allowed to recover. This animal was shown to be immune to the disease by challenge with N. salmincola metacercariae from fish. A susceptible control dog given the same number of metacercariae developed the disease and died. Intracytoplasmic inclusion bodies were seen in stained lymph node cells from all dogs that developed the disease. |
