    Under the bovine leukosis eradication campaign in Shimane Prefecture since 1987, the prevalence rate of antibody against bovine leukemia virus was reduced to 0.27% in a population (about 2, 950 head) of Japanese Black beef cattle by 1990. Random sampling with a hypergeometric distribution from a no prevalence group was applied to the eradication by simulation. The simulation of bovine leukosis eradication with the initial prevalence rate (0.27%) was also examined. As a result, 2.4±0.42 (mean±95% confidence limit) positive cattle were detected thereafter in the population at risk.

    Four abnormally born calves with weakness and irregular bend of the vertebral column, cerebellar hypoplasia, or arthrogryposis of the four legs showed Toxoplasma-like tissue cysts and tachyzoites in the brain, skeletal muscle, or myocardium. Tissue cysts were round to ellipsoidal in shape with a thick cyct wall and contained numerous bradyzoites which were crescent in shape with a marginated nucleus. Formaldehyde-fixed tissue cycts and tachyzoites were subjected to immunohistochemical examinations (ABPC test; Lindsay and Dubey, 1989) using rabbit anti-Toxoplasma gondii, anti-Hammondia hammondi, anti-Neospora caninum, and anti-Sarcosystis crusi sera as primary antibody. Positive reaction was obtained only with anti-N. caninum serum. The present results suggest the occurrence of N. caninum in Japan and its causative role in the development of abnormal delivery in calves.

    In September, 1990, a lactating Holstein-Friesian cow on a farm suffered from astasia and leukopenia. A virus was isolated from the erythrocytes and plasma of the blood of the cow by the intracerebral inoculation of suckling mice. The virus induced cytopathic effect and formed plaques in Vero and HmLu-1 cell cultures, and was identified as Ainovirus, a member of the Simbu group of the family Bunyaviridae, by the neutralization test. The physicochemical properties of the virus were compatible with those of Ainovirus. Most of other cows on the farm showed significant increases in the neutralizing antibody titer against Ainovirus, indicating that the virus was prevalent among the cows on the farm.

    Two cases of canine malignant basal cell tumor were observed. One originated in the skin of the left dorsolateral abdominal area and showed a combined histological appearance of solid and adenoid types. Pulmonary and adrenal metastases were noted in this case. The other originated in the skin of the cervical area. The tumor cells showed a keratinizing tendency and severe invasion to the surrounding tissues.

    A 6-year-old, male Shetland sheepdog was presented to Azabu University Veterinary Hospital due to listlessness and lack of appetite. On physical examination, the abdomen was enlarged and abdominal cystcentesis revealed the peritoneal fluid of a dark and brownish color, which suggested to be a bilepigmented fluid. Serum biochemical analysis revealed elevated glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and alkaline phosphatase (ALP). Radiography revealed a ground-glass density in the abdomen. Based on these results, rupture of the common bile duct was suspected. An emergency laparotomy was performed and about 600 ml of the bile-stained fluid was removed. After careful examination of the fluid, it was found to originate from a rupture in the common bile duct. The common bile duct was ligated, and a cholecystojejunostomy was performed. The dog recovered from the surgery without any complications.

    A 4-year-old male Japanese cat died of renal failure with anorexia and emesis. Necropsy revealed swelling of the left kidney with blood coagulation in the renal pelvis and hypoplasia of the right kidney. Histologically, congestive edema and parasitic embolism, which was caused by Dirofilaria immitis infection, were observed in the lung. The characteristic change in the left kidney was eosinophilic interstitial nephritis with formation of tissue clefts. These pathological findings suggested that renal failure in the present case might be caused by parenchymal injury following larval migration of Dirofilaria immitis in the left kidney.

    Two 30-day-old puppies, a female mongrel (case 1) and a female Shetland sheepdog (case 2), which died without characteristic symptoms, were pathologically examined. Histopathologically, basophilic intranuclear inclusion bodies were present in the nuclei of the cardiac muscle, and necrosis of the cardiac muscle fibers was frequently observed in case 1. Case 2 showed myocarditis characterized by mononuclear cell infiltration and basophilic intranuclear inclusion bodies. Immunohistochemically, these inclusion bodies gave a positive reaction against antibody to feline panluekopenia virus. Ultrastructurally, the inclusion bodies were composed of spherical viral particles approximately 20 nm in diameter. From these findings, both cases were diagnosed as myocarditis due to canine parvovirus.

    A total of 3872 pigs from 33 farms, which were slaughtered at E Meat Center in Ehime Prefecture were examined for relationships between prevalence rates of diseases and grades of the carcasses. A positive correlation existed between grades of the carcasses and mycoplasmal pneumonia of swine (MPS) out of 14 chronic diseases, but did not between grades of carcasses and 13 other chronic diseases. On the basis of these results, farmers having a high MPS prevalence rate received advice regarding animal hygiene practice with the view of lowering the prevalence. The examination of the effect through the above advice by monitoring the seropositive rate to MPS on the farms revealed a decrease in the MPS seropositive rate of breeding pigs from 63.2 (before the advice) to 20.8%(after the advice). Autopsy findings also indicated a decrease in the MPS prevalence rate from 46.5 (before the advice) to 34.2%(after the advice), suggesting the effectiveness of the above advice.
