    Seven fatal cases of natural infection with attaching and effacingEscherichia coli (E. coli) in 3- to 40-day old calves occurring in Shiga Prefecture from 1991 to 1993 were investigated pathologically and bacteriologically. Diarrhea was seen in 5 of 7 cases, and histopathology and electron microscopy revealed that numerous colibacilli adhered to the colon enterocytes and the effacing of epithelial microvilli in all cases. AllE. coliisolates possessed theeaegene, but not EAF, producing verotoxin 1. The isolates were of O26: H11 (4 cases), O118: H16 (2 cases) and O103: H2 (1 case).

    The serotypes ofActinobacillus pleuropneumoniae (APP) isolated from swine cases in the last 13 years were retrospectively studied and bacteriology of pneumonic lesions on slaughtered pigs and serology by complement-fixation test on swine farms were made in 1993 and 1994. All isolates before 1989 were of serotype 2, while serotype 5 in 1989 and serotypes 1 and 7 in 1994 were detected. Almost all the cases exhibited fibrinous pleuropneumonia, and in 1994 there were one case with meningitis due to serotype 7 and the other with verrucous endocarditis and arthritis due to serotype 2. In 1994, all the 12 isolates from 85 nodular abscess lesions in the lungs of slaughtered pigs were of serotype 2. Streptomycin resistant strains were isolated in 1984 and 1989 and the frequency of multiple drug resistant strains increased after 1992, and the serotypes 1 and 7 isolates were shown to have plasmids. Of 231 sera from 17 herds surveyed in 1993 and 1994, 9 sera from 4 herds, 84 from 12 herds, 1 from 1 herds, and 4 from 1 herds were positive for serotypes 1, 2, 5, and 7, respectively.

    A total of 1, 441 isolates ofA. pleuropneumoniaefrom swine pneumonic lungs collected during 1989 to 1995 were examined for serotypes and susceptibility to antimicrobial agents. Of the 1, 441 isolates, 757 (52.5%) and 523 (36.3%) were of serotypes 2 and 1, respectively, while 90 (6.2%), 22 (1.5%), 21 (1.5%) and 20 (1.4%) isolates were of serotypes 5, 7, 8, and 3, respectively. The remaining 7 (0.5%) and 1 isolates were of serotypes 12 and 9. In 1990 and 1991, the isolation rate of serotype 2 were lower and that of serotype 1 were higher. All the isolates were highly sensitive to spiramycin, kitasamycin, erythromycin, lincomycin, novobiocin and colistin, whereas 915 (63.5%) were resistant to some drugs. The resistant isolates were 338 (44.6%) of 757 of serotype 2, 13 (61.9%) of 21 of serotype 8, and most isolates of serotypes 1, 3, 5, 7, 9 and 12.

    Eleven SPF White Leghorn female chickens were inoculated intratracheally with Mycoplasma gallisepticum, while 11 chickens withM. synoviae. Sera were examined for dot-immunobinding (DIB) and agglutinating antibodies every week for 10 weeks after inoculation. All sera from inoculated chickens were shown to have high positivity against the inoculated organisms in both tests, whereas sera from uninoculated control chickens were negative. In agglutination test remarkable false-positive reaction was observed with sera from both inoculated groups. In the DIB test, however, non-specific reaction was never observed. Results of the DIB test with sera at their 100-fold dilution coincided with the results of agglutination test at a level of 86% with MG and 92% with MS antigen.

    Three lesser sulphur-crested cockatoos (Cacatua sulphurea) with systemic feather abnormality were examined for clinical signs and histopathology. The feathers were widely lost, discolored and dystrophied with deposition of black pigment. There were some decrease in quantity of fine feather powders as well as overgrowth of the beak and nails. Histopathologically, necrobiosis of the feather epithelium and exudative or occasionally granulomatous folliculitis were noticed. Intranuclear inclusions were formed within feather epithelial cells, and intracytoplasmic inclusions were within macrophages in the feather epithelium and the feather pulp. The cases were diagnosed as psittacine beak and feather disease. Oral administration of propagermanium was temporarily effective.

    Dogs 5 to 7 years of age weighing 7.5 to 13.8kg fed active egg white product (1g/kg/day) for 1 or 7 days were examined for the activity of peripheral neutrophils and macrophages by chemiluminescence (CL). During 4 days after feeding for 1 day-group, the CL count/neutrophil was 2.5 fold higher than that before feeding, and the CL count/macrophage in 1 day after feeding for 1 day-gorup was observed 5.5 fold higher than that before feeding. After feeding for 7 days, the CL count/neutorphil during 3 to 4 days after feeding was about 3 fold higher than that before feeding. The macrophage activity, however, was slightly reduced 1 to 2 days after feeding, turning high levels at 3 day after the end of feeding.

    A male Japanese domestic cat of unknown age was examined because of anorexia and depression. The cat had pale mucous membranes and enlargement of spleen and liver. The peripheral blood was markedly anemic with remarkable increase of nucleated erythrocytes at various stages of maturation. The cat died 5 days after presentation, and increased number of erythroblasts at different stages of maturation were seen in the bone marrow. The case was diagnosed as myelodysplstic syndrome (MDS-Er).

    A Japanese badger (Meles meles anakuma) infected with canine distemper (CD) was examined pathologically. Gross findings exhibited congestion of the lung and gastrointestinal tract, and hard pads. Histopathologically, broncho-interstitial pneumonia, catarrhal gastroenteritis, non-suppurative meningoencephalitis and purulent dermatitis were observed, and cytoplasmic and intranuclear eosinophilic inclusions were found in the epithelial cells of various tissues, lymphocytes and reticular cells in lymphoid tissues, and neurons in the brain. Immunohistochemical analysis revealed cells containing CD virus antigen in these affected cells.

    Two strains ofCampylobacter jejuniisolated from a human sporadic diarrhea case and a healthy cow were examined to clarify the quantity of endotoxin production and pyrogenicity to rabbits. Both strains were grown microaerobically in brain heart infusion broth at 42°Cfor 7 days. These culture supernatants filtered through 0.45 and 0.20μm-filter after centrifugation were endotoxin-positive in the Limulus test at a dilution of 106. And the minimum pyrogenic dose which elicits a rise in temperature of 0.6°Cin rabbits, was 1ml/kg administration of 102diluted sample with both strains.

    A total of 44, 724 freshwater fishes of 18 species collected in the eastern Aomori Prefecrure for a period. from July 1992 to December 1995 were examined for the larvae ofGnathostoma nipponicum. Five fish species, Misgurnus anguillicaudatus, Silurus asotus, Chaenogobius urotaenia, Oncorhynchus masou, andTribolodon hakonensis, were shown to be infected and a total of 322 gnathostome larvae were detected and identified as the advanced third-stage larvae. Salmonidae and Cyprinidae fishes, includingO. masouandT. hakonensisrespectively, might be the more important as direct sources of human Gnathostoma infection in the northern part of Honshu, Japan.
