Acute and chronic canine parvovirus myocarditis following intrauterine inoculation.
Canine myocarditis virus was inoculated into puppies in utero 8 days before parturition. Puppies were clinically normal at birth. One puppy died 23 days after inoculation and a second puppy was comatose before euthanasia on day 27 post inoculation. Both had acute, non-suppurative myocarditis, and parvovirus was isolated from the heart of each pup. Two other puppies remained clinically normal until euthanasia at 87 and 131 days after inoculation. These latter puppies had extensive, focal fibrosis within the myocardium. Despite weekly monitoring, ECG changes were not recorded. The apparent predilection of canine parvovirus for cardiac myocytes is discussed.

Experimental infection of 35, 50 and 60 day old pig foetuses with porcine parvovirus.
Foetuses of six seronegative gilts, two of which each respectively 35, 50 and 60 days pregnant, were inoculated intrauterinely with porcine parvovirus (PPV) and examined 7 and 11 days after inoculation. HI antibody was not detected in any of the foetuses although all but one gilt developed low levels of antibody. All but one of the foetuses inoculated with PPV died in utero prior to examination at 11 days after inoculation. Infection also spread to non-inoculated litter mates. Histological changes were mild in the gilts but there was widespread tissue necrosis in infected foetuses, and intranuclear inclusion bodies were observed in cells of the liver, lung, kidney and cerebellum. The increased survival of foetuses infected at later stages of gestation appeared to be related to increased numbers of mononuclear cells then present in many tissues.

Association of a parvovirus with an outbreak of foetal death and mummification in pigs.
A parvovirus was isolated during an outbreak of mummifications and abortions in a commercial piggery. Stillborn piglets from which virus was isolated or in which parvovirus antibody was detected had widespread inflammatory lesions. Lesions were also seen in apparently healthy piglets from affected litters.

General pathology of experimental swine vesicular disease.
Twenty-four minimal disease pigs were inoculated intracerebrally, intravenously or intradermally with an English strain of swine vesicular disease virus. In the skin, snout, tongue and tonsil the main lesion was a full-thickness coagulative necrosis of the stratified squamous epithelium. In the renal pelvis, bladder, tonsillar crypts and the collecting ducts of salivary glands and pancreas, epithelial degeneration with the formation of periodic acid-Schiff-positive material were consistent features of this disease. Histopathological examination alone could not be relied upon to differentiate between well-established skin lesions caused by swine vesicular disease and foot and mouth disease. The relationship between vesicular disease and Coxsackie B5 is discussed briefly.
Neuropathology of experimental swine vesicular disease in pigs.
A total of 26 young pigs were inoculated intracerebrally, intravenously or intradermally with the UKG27/72 strain of SVD virus, grown in tissue culture, and killed two, four, eight or 16 days after exposure. Overt nervous symptoms were seen only in pigs inoculated intracerebrally, but all pigs of all groups showed a non-suppurative meningitis and panencephalomyelitis principally affecting the mid- and fore-brain. Ganglioneuritis with intranuclear inclusion bodies in perineuronal amphicytes were found to be the most consistently useful characters for distinguishing SVD from other virus encephalitides of pigs. Spinal radiculitis was a feature of the early stages of CNS involvement and lesions were found also in the optic nerve, retina and cornea.
[Myocardial fibrosis. A case of falling disease (author's transl)].
A case of chronic progressive heart failure in a bull, resulting from myocardial fibrosis, is reported. In view of the low concentration of copper in the liver, this condition is believed to be similar to that termed falling disease.
