    An outbreak of fowl cholera occurred in a goose flock at Aomori Prefecture in March 1987, showing depression, anorexia, and diarrhea resulting in acute death in 1, 160 (73%) of 1, 582 birds. Necropsy of 8 dead cases revealed multiple necrotic foci in the liver and spleen and multiple petechiae in the heart.Microscopically, multiple necrosis and heterophilic infiltration with bacterial colonies were seen in the heart, lung, kidney and intestine. Pasteurella multocida was isolated in pure culture from the heart, lung, liver, kidney, spleen, ovary and testis as well as ascites and peripheral blood. The isolates were shown to be of Carter's capsular type A, Heddleston's somatic type 1 and Namioka's somatic type O-5, and to be highly pathogenic for geese and chickens.

    Immunological and clinical responses were compared between pigs inoculated with both Aujeszky's disease (AD) and hog cholera (HC) live vaccines and those with either AD or HC live vaccine. The two vaccinations were made at a four week-interval or simultaneously. None of vaccinated pigs showed clinical signs and there was no significant difference in neutralizing antibody titers between the groups (p<0.05).

    Holstein cows were examined for blood composition about 10 days before and 7, 30 and 60 days after parturition as well as time-period to the postparturient estrus return. There were correlations between improper feeding such as excess DCP and insufficient TDN and abnormal values in Gros reaction and albumin/globulin ratio. In those having abnormal blood values metabolic disorders, dystocia and retention of afterbirth occurred and the estrus return was significantly delayed.

    One-hundred twenty-three farm horses reared in Iwate Prefecture, Japan were surveyed for helminths by fecal examination and culture. Strongyle and Parascaris eggs were detected from 99.2% and 20.3% of horses examined respectively. Infective larvae were detected by fecal culture showing positivity rates as follows: Strongylus vulgraris 19.1%, S. edentatus 47.0% and S. equinus 7.0%, Cyathostominae subfamily 98.3%, Gyalocephalus spp. 13.9%, Poteriostomum spp. 19.1% and Triodontophorus spp. 29.6%.

    Three Holstein Friesian cows aged 10 to 44 month old showed systemic and nodular dermatitis in the summer of 1990 and 1991, and the recovery was seen within a week after administration of adrenocorticoids and antihistaminics. Biopsy revealed incrustation of the epidermis and degeneration of collagen fibers with a considerable infiltration of eosinophiles in the dermis, suggesting allergic etiology.

    In cats with experimentally induced acute renal failure, a silicon disk catheter was placed in the peritoneal cavity, and dialysis was made with 40 ml/kg containing 130, 140 or 155mEq/l sodium. There was no significant difference in drainage volumes, showing a mean maximum level of 12.3ml/kg at 1h-dialysis. With 130 mEq/l sodium serum sodium concentration tended to decrease, and sodium level exceeded the normal one after dialysis with 155 mEq/l sodium. With 140 mEq/l sodium, the serum sodium level remained within the normal range.

    The growth of the crown and root in the canine tooth of beagle dogs were observed macroscopically and radiographically, and changes of occlusion with age were investigated. Completion of growth in the crown of the canine tooth was observed in both mandible and maxilla, and its eruption was accompanied by develop, ment of the dental root. The permanent canine erupted on the lingual side of deciduous canine in the mandible, and on the mesial side of the deciduous canine in the maxilla. Movement of the permanent canine to normal occlusal position(buccal direction in mandibular canine, and distal direction in maxillary canine)was followed by the loss of the deciduous canine. Coexistence of the permanent and deciduous canines occurred for about 2.4 weeks in the maxilla and about 1.4 weeks in the mandible, on average. Macroscopically, the growth of the permanent canine was completed by 33 weeks of age in the mandible and about 34 weeks of age in the maxilla. The mature root of the permanent canine was recognized radiographically at about 43 weeks of age in the mandible and 47 weeks of age in the maxilla.

    In a 8-year-old female Himalayan weighing 3.8 kg with tachypnea and ascites since 1 month, congestive sign was markedly improved by oral medication of digitalis, diuretics and vasodilators. The cat was died on 52 days later due to deteriorated renal failure, and dilated cardiomyopathy was confirmed by necropsy.

    A total of 1, 169 rats, mostly Rattus rattus, trapped in restaurants within the buildings of central Tokyo were examined for Yersinia spp. in the large intestine during a period from January 1988 to March1990. Yersinia spp.were isolated from 348 of 1, 169 rats (29.8%) Y.enterocolitica from 175 rats (15.0%), Y. frederiksenii from 177 rats (15.1%), Y. intermedia from 49 rats (4.2%) and Y. kristensenii from 12 rats (1.0%). Of 175 isolates of Y.enterocolitica, 16 were of serotype 0: 5 (biotype 1, 8strains) and 0: 7, 8 (biotype 1, 8 strains)., None of the Y.enterocolitica isolates were of pathogenic sero-nor biotype and they had no pathogenic plasmids.
