    Two-to 3-month-old piglets raised in a semi-high floor pen showed anemia, emaciation and bloody diarrhea after weaning, and 40 of 400 animals died. Three dead and autopsied cases were severely parasitized with Trichuris suis in the cecum and colon. While transient recovery was seen in the surviving animals after drug treatment, similar symptoms appeared at 4 to 5 months of age and further 20 animals died. Two dead cases examined were parasitized with T. suis and Salmonella choleraesuis was detected from the lung, kidney, liver and jejunal and cecal contents in one of them.

    Haemophilus parasuis was isolated from the nasal cavity in 257 of 318 (80.8%) conventional pigs reared in 12 conventional farms in Shizuoka Prefecture, whereas 3 SPF farms were negative. Fifty-one (83.6%) and 10 (16.4%) of 61 isolates examined were shown to be of types I and II, respectively, by polyacrylamide-gel electrophoresis. Complement-fixation (CF) antibody against H. parasuis was detected in 171 of 203 (87.4%) conventional pigs, whereas 98 SPF pigs examined were negative for the antibody. Of the slaughter house pigs 278 cases examined had the CF antibody, while no correlation between the antibody titers and chronic serositis was demonstrated.

    A total of 100 Escherichia coli isolates from 92 cases of bovine peracute mastitis were examined for their properties, and no specific markers for the disease was detectable. Thirty-one isolates showed mucoid type colonies and 80 were motile. Hemolysin was produced by 14 isolates. Most isolates had biochemically common properties, greatly varying in O-groups. All the isolates were serum resistant. None of them produced verotoxin nor heat-stable enterotoxin.

    A 2.5-month-old, male Holstein-Friesian calf with ataxia and visual disturbance was subjected to electroencephalographic (EEG) and pathological examinations. The EEG in awake state revealed a wave pattern dominant in high amplitude (40-120 μV) slow waves during the whole period of recording, while almost normal pattern appeared transiently. The EEG in sleep state revealed a markedly high amplitude exceeding 200 μV. The animal was responsive to photic stimulations, but not to auditory ones. Microscopy revealed a widespread spongy degeneration throughout the central nervous system.

    By gel filtration a high level of LDL and a low level of HDL were found in the serum of calves immediately after birth, showing a distribution patterns almost similar to those of adult human. The LDL level was decreased and the HDL level increased on day 6 after birth, attaining the pattern of growing dairy cows. In dairy cows the LDL fraction disappeared at 30 days before parturition and remained undetectable throughout the milking period. The HDL fraction began to increase after parturition, but it was estimated to be lower in specific gravity and larger in size, possibly cmtaminating the LDL fraction.

    Surgical treatments of the impacted canine tooth were carried out in 8 young dogs, and the results were successful in 12 out of 14 cases (85.7%). The treatments consisting of surgical correction by immediate tipping movement, fenestration of the gingiva, and removal of the impacted tooth, were applied to 14 cases radiographically showing the immature tooth root and no abnormalities in the tooth root or alveolar bone. Impacted teeth were seen in 8 regions of the maxilla and 6 regions of the mandible. Mesioversion was seen in almost all maxillary impacted teeth, while linguoversion or lingual mesioversion in all mandibular cases. Surgical correction was carried out by immediate tipping movement after removal of the retained deciduous canine with or without resection of the alveolar bone. Fixation of the moved teeth was done using a wedge made from the deciduous canine root, which was driven into the vacant alveolar cavity after moving. An additional fixation using a steel wire and/or self-curing resin was done, if necessary.

    Pirenoxine ophthalmic solution, an anticataract drug for human use, was tested for its effectiveness in the treatment of senile incipient cataract in dogs. Of 18 cases treated with the drug, 13 (72.2%) cases responded favorably resulting in improved lens opacity or delayed progress of the disease. Hyperemia and epiphora, both being local sensitive symptoms, were obsereved in one case. Improved lens opacity was noticeable after medication for 81.6 days on average, and the effect was pronounced in younger cases with cortical cata-ract.

    Intussusception with ectopic mummified fetus was seen in a 5-year-old female Japanese cat. The ovariohysterectomy was also preformed. The ileal intussusception was surgically resected and an end-to-end anastomosis was established with successful recovery after operation. The uterus showed no gross changes. A full term-mummified fetus was faintly attached to the omentum without formation of the placenta.

    Slaughter pigs in Okinawa Prefecture were examined for Sarcocystis infection from August 1991 to February 1992. Thirteen of 100 (13%) fattened and 94 of 200 (47%) breeder pigs were positive for the infection with S. miescheriana (106 cases) and S. porcifelis (1 case). The infection rate seemed to be higher in the southern Okinawa, while distributed all over the prefecture. S. miescheriana had the thick and radially striated cyst wall, whereas S. porcifelis had the thin and smooth wall. A dog fed S. miescheriana-infected meat excreted sporocysts in the feces on day 11 or later after ingestion.
