Plain-English summary
Three dogs in Washington State were brought to the vet showing signs of illness, including depression, loss of appetite, and diarrhea. Despite treatment efforts, the dogs either died or were humanely euthanized due to their poor response to therapy. A thorough examination revealed severe infections affecting their lymph nodes and liver. This situation indicates a new type of infection caused by a bacteria previously thought to only cause mild symptoms in dogs.

Abstract
The genusincludes obligate, intracellular bacteria responsible for diseases including Potomac horse fever caused byand salmon poisoning disease (SPD) caused by. The(SF) agent is a member of this genus previously associated only with mild clinical signs in dogs. Between 2013 and 2016, 3 dogs in Washington State (USA) presented with disease suggestive of SPD, butwas not detected by molecular techniques. Clinical signs included depression, anorexia, and diarrhea. Cytologic examination of aspirates supported a diagnosis of granulomatous lymphadenitis with organisms suggestive of. Dogs either died or were humanely euthanized due to poor response to therapy. Necropsy findings included lymphadenomegaly and hepatomegaly. Histopathology identified granulomatous and lymphoplasmacytic splenitis, lymphadenitis, enteritis, and hepatitis with extensive necrosis.DNA was detected using genus-specific primers and direct sequencing showed 100% sequence identity to the SF agent in all 3 dogs. This is the first clinicopathologic description of severe disease in dogs attributed to the SF agent. These findings may suggest the emergence of a novel neorickettsial disease in the Pacific Northwest.
