    In a farm raising 60 sows some 60-70-day-old piglets showed severe respiratory symptoms and died in April 1995. In 3 cases autopsied severe pneumonia was observed and histopathology revealed nonpurulent interstitial pneumonia and perivascular cuffing in the brain. Porcine reproductive and respiratory syndrome (PRRS) virus and reovirus type 2 were isolated from the brain, lung and tonsil, by inoculation onto MARC-145 and CPK or HmLu-1 cell cultures, respectively.

    Six isolates of avian infectious bronchitis virus (IBV) in Hiroshima Prefecture (1976-1994) were subjected to typing by the restriction enzyme analysis of amplified RT-PCR fragments. Three of the six isolates showed cleavage patterns, respectively, identical with those of the Ishida, ON and Kita-1 strains. Another isolate exhibited a pattern similar to that of the C-78 strain. The cleavage patterns of the remaining two were the same being different from any of those previously published.

    From 3 cases of bovine mastitis showing severe mammary swelling and hardening aswell as discharge of a lot of small clots in the milk Prototheca zopfii, was isolated. Two cases recovered by early treating with kanamysin. Serum from the remaining unrecovered case reacted with culture supernatant antigen of the isolate by gel immunodiffusion, and histopathology revealed chronic mastitis with a number of bacteria and severe infiltration of lymphocytes and plasma cells. The two recovered cases were seronegative in immunodiffusion.

    Eleven dogs subcutaneously received commercially available microchips for identification. None of them showed general and local clinical disorders for one monthafter implantation. No moving of the chips from the implanted site was observed, and reading of the code number was simple and easy.

    A young female pug dog with multicentric lymphoma (stage V) showing markedly enlarged superficial lymph nodes, was subjected to a combination chemotherapy, which was effective in reducing the lymph nodes in size with extensive necrosis of tumor cells. On day 23 of the chemotherapy, however, the case had a generalized seizure with opisthotonus and died on day 33 despite anticancer and anticonvulsant therapies, and histopathology revealed that the cerebral and cerebellar leptomeninges were infiltrated with proliferated neoplastic lymphocytes and severe perivascular infiltration of neoplastic cells was observed in the cerebral parenchyma, suggesting that chemotherapy might be not effective on lymphoma cell proliferation in the brain.

    A 9-year-old mongrel male cat with anorexia and weight loss was revealed to havea tumor 4 cm in diameter in the abdominal cavity by palpation, and radiography demonstrated ectopia of the intestinal tract to the upper right with retention ofgas in the same region. By laparotomy, two solid masses were observed in the ileum with enlarged mesenteric lymph nodes. The ileum including the mesenteric lymph nodes was extensively by excised, and histopathologically, the mass was diagnosed as globule leukocyte tumor (GL tumor), possibly causing ileus. The cat survived postoperatively for months without signs of illness and died with ascites at6 months.

    From April to July 1997, six outbreaks of influenza in school children occurred in Okayama Prefecture. A total of 34 throat swabs from 21 school children and from 13 patients with symptoms of the upper respiratory tract of outpatients in some hospitals, were examined for influenza virus, and influenza B viruses wereisolated from 7 school children and 3 patients. By hemagglutination inhibition (HI) tests, 8 of the 10 isolates were antigenically distinct either from the vaccine strain B/Mie/1/93 used in 1996 and 1997 or from the influenza B isolates from 1990 to 1995 in Okayama Prefecture. For the B variant isolate (B/Okayama/68/97) HIantibody was negative in 77 of 100 inhabitants in Okayama Prefecture, and all 20children younger than 10 years old were sero negative.

    Using commercial serodiagnostic kits, IgG antibody to Helicobacter pylori (H. pylori) was detected at high titers in 98% of pigs in one region of Hokkaido, while 0% in another region. In dogs and cats examined, antibody was detected in 58% and 83%, respectively. The antibody titres were higher in older dogs, but no agedependent difference in titers was seen in cats. The results were well correlated between two serodiagnostic kits (GAPTM-IgG and Pyloriset Dry).

    Two young sheep were inoculated orally with 1×107 sporocysts of Sarcocystis arieticanis from canine feces stored at 4°C for 3 months. Two peaks of fever were recognized 14 and 26 days after inoculation and at the second peak, pulse and respiratory rates increased and appetite was lost. In one case sacrificed on day 16 postinoculation, mesenteric lymph nodes were enlarged and edematous, and the first generation schizonts (14-44×12-20μm in size; n=50) were detected in the mesentery and its lymph nodes. In the other case necropsied on day 30 postinoculation was shown to have asites, hydrothorax and hydropericardium, showing ecchymosis and petechiasis in most organs. Histopathology revealed hemorrhage and mononuclar cell infiltration in most organs, and the second generation schizonts (10-25×6-14μm; n=50) were observed in the small blood vessels.
