Infectious canine hepatitis in 4 dogs in Switzerland

Infectious canine hepatitis in 4 Dogs in Switzerland Four dogs presented with nonspecific symptoms of lethargy, vomiting, diarrhea, fever and weakness. Laboratory results were consistent with hepatopathy and disseminated intravascular coagulation. Three dogs died, one survived. In the three deceased dogs, a diagnosis of infectious canine hepatitis (ICH) was made based on histological findings and positive immunhistochemistry results for canine adenovirus-1 (CAV-1). In the surviving dog, an antemortem diagnosis of ICH was determined via positive polymerase chain reaction results from blood, occular, nasal and preputial discharge as well as from urine. Since the introduction of widespread vaccination, the incidence of CAV-1 infection in dogs is low. However, the disease has not been eradicated and should be considered when clinical signs consistent with ICH are present.
