Systemic canine herpesvirus 1 infection. All the photographs in this figure show the same puppy. A, Severe acute hydrothorax and multifocal acute hepatic necrosis, situs of thoracic and cranial abdominal cavity. Pleural effusion and hepatic necrosis are common findings in herpesvirus infections. Canine herpesvirus infection is commonly diagnosed in puppies that died during the first 2 weeks of life. B, Severe acute interstitial pneumonia, lungs. The lungs are poorly collapsed and mottled red-beige. Compare with normally colored and collapsed lungs shown in Figure 31-2. C, Multifocal, severe, acute renal necrosis and hemorrhage, sagittal cut, kidney. Petechiation on the cut (left) and capsular (right) surface in the puppy is characteristic for an infection with canine herpesvirus 1.
