    Actinobacillus suis was isolated from 4 septicemic suckling piglets of two farms in November 1990 and January 1993. The isolates could grow on MacConkey agar medium of two of four companies tested, while the isolate showed little or no growth on the other two. These isolates were highly sensitive to erythromycin, enrofloxacin, danofloxacin and sulfamethoxazole-trimethoprim, while resistant to kanamycin and spiramycin. Further, some were resistant to penicillins and streptomycin.

    Serum α1-acid glycoprotein (α1AG) and sialic acid (SIAL) of heifers were examinedin relation to changes in breeding forms in a pubulic pasture land. The α1AG and SIAL levels were significantly higher after pasturing than before, returning to the previous levels at 2 months of pasturing. The heifers reared within the public drylot during winter showed similar changes in α1AG, while the level was lower, and no changes were observed in SIAL levels. The results suggested that heifers might be in immunosuppressive state during some weeks after moving to different breeding forms, such as pasturing.

    Chromosomal anomalies were found in 5 cases of Japanese Black calves with congenital defects. Case 1 had complicated defects of atresia ani, recto-vaginal fistula and fused kidney. Chromosome studies showed structural anomalies such as isochromatid gap, chromatid gap, chromatid break and fragment in 77% of the cells examined. These anomalies were also found in 3 to 16% of the cells from her maternal grand mother, dam and sire. Case 2 had dupulicated uterus and umbilical inflammation. Chromosome studies showed chromatid gap and autosomal trisomy. Case 3, 4, and 5 had atresia ani, prolonged gestation and rib fracture, and umbilical hernia and short mandible, respectively. Each of them showed autosomal trisomy. As the maternal age at parturition of these 5 calves were 8 to 14 years, its high age may be a contributing factor for these chromosomal anomalies.

    A case of multiple myeloma was found in a six-year-old female Gechingen miniature pig. A few atypical plasma cells were present in the peripheral blood, but the animal did not have elevated γ-globulin in serum. At necropsy the spleen was highly enlarged with multiple nodules. Each of the sternum and two ribs had a neoplastic nodule on its surface. Histologically, there were neoplastic cells in the bone marrow, spleen, liver, kidneys and pancreas, and bone destruction by neoplastic proliferation was detected in the cortex of the ribs. The neoplastic cells were of moderate size, oval to round in shape, and had an eccentrically placed nucleus with chromatin clumps. The cytoplasm was weakly basophilic in haematoxylin and eosin preparations and pyroninophilic, and frequent cells contained PAS positive bodies. There was intracytoplasmic IgM in many neoplastic cells, and dilated cisternae of rough endoplasmic reticulum were the most predominant ultrastructural feature of the neoplastic cells. This tumour was a nonsecretory IgM myeloma, which was very rare in domestic animals.

    An acutely dead 9-day-old calf showed irregular shaped necrotic foci in the ruminal mucosa, subcapsular hepatic abscesses from rice-grain to red bean in size and enlarged mesenteric lymph nodes at autopsy. Histopathology revealed infiltration of neutrophils and fibrinous thrombi in ruminal ulcers as well as abscesses and fibrinous thrombi in the liver. The ruminal ulcer and hepatic abscesses were strongly positive by immunostain for Fusobacterium necrophorum antigen.

    The postprandial plasma creatinine (Cre) level significantly increased in relation with Cre content of the diet, decreasing to the preprandial level at 14 hr after consumption. Food intake should be attended at estimating the plasma Cre level in cats.

    Eighteen puppies naturally infected with Toxocara canis received orally 0.25 mg/kg milbemycin oxime (MO). In 12 dogs, eggs per gram feces (EPG) became negative by 30 days after treatment when no adult worms were recovered. In 4 dogs, the fecal EPG became negative by 7 days post-administration, while they harbored 1 to 3 mature or immature worms in the intestine at 30 days after administration. In the other 2 dogs, though fecal eggs disappeared by 7 days, a few eggs were detected in feces at 30th day. Of these 2 dogs given another 0.25 mg/kg, one excreted 1 worm at the 32nd day, while the other did not. At 30 days after re-treatment, fecal eggs were negative and no adult worms were recovered.

    A male 10-year-old mongrel dog with swelling of all the limbs and lameness was diagnosed clinically and radiographically as hypertrophic pulmonary osteoarthropathy, showing irregular border of the humerus, radius and ulna, periosteal proliferation of the femur, peritibial and perifibular new bone formation and an irregular surfaced mass in the thorax. Hypocalcemia, hyperphospheremia and lowered plasma vitamin D metabolites were revealed. Histopathology demonstrated the atrophied parathyroids, porosity of tibial compact bone and infiltration of bronchioloalveolar carcinoma in the lung, especially right diaphragmatic lobe, with heart worm embolism in some pulmonary arteries.

    In dogs fed a standard amount diet once daily at a fixed time, the mean duration of postfeeding contractions were 16.6, 13.3 and 15.9 hours in the antrum/duodenum, jejunum and ileum, respectively. During the interfeeding migrating contractions (IMC) repeated, followed by phase Ill until the next feeding and the mean intervals of IMC ranged from 87.3 to 98.1 min. With increaced amount (120-140%) of diet, the duration of postfeeding contractions was elongated, while the IMC was shortend. There was a significant correlation (P < 0.01) between the feeding amount and duration of postfeeding contractions. In cases fed twice a day equally divided amounts of the diet, the mean duration of postfeeding contractions was elongated, and the IMC phase was shortened with decrease in frequency. The freely fed dogs showed no IMC phase. From these results, feeding the standard amount of diet once a day should be recommended for dogs to have a balanced pattern of post-and inter-feeding gastrointestinal movement.

    Nodular lesions within the striated muscle supposedly due to sarcocystis infection were detected in all or a part of body in 267 of 49, 630 (0.54%) breeding sows slaughtered in Okinawa Prefecture from January 1990 to December 1993. The affected cases were distributed all over the prefecture increasing in number year by year, and the prevalence rate seemed to be higher in the central and southern Okinawa. The nodules were yellowish white in color with cheeseous or sand like contents and were of granulomatous lesion histopathologically. The degenerated cyst wall of S. miescheriana was seen at the center of nodules in 3 of 105 cases examined.

    Lymphonodular white spots were detected in the lung of slaughtered pigs with pulmonary petechiae and multiple milk spots in the liver. These noduli mainly consisted of follicular hyperplasia of lymphoid cells, including a few sections of the third stage larvae of Ascaris suum at the center of the foci in some cases. A number of Ascaris suum eggs were frequently detected in feces of pigs with pulmonary lymphonodular lesions.

    Sarcocystis fayeri infection was derected in 7 of 50 slaughtered horses from July to August in 1994. The cysts were 1, 000-5, 000 × 200-300μm in size, with the cyst wall 1 to 3μm thick. Bradyzoites were bananashaped and 15-17 × 4-4.5μm in size. Two adult dogs fed with S. fayeri-infected horse meat excreted sporulated sporocysts (11-13 × 7-9μm) and oocysts in the feces on day 12 or later after ingestion.
