    From February to September 1991 on a farm of Kumamoto Prefecture, 15 calves showed pneumonia with fever, cough and nasal discharge, and Mycoplasma bovis and Pasteurella multocida were isolated from the lung of one of 5 fatal cases. M. alkalescense, M. bovis, P. multocida and P. haemolytica were isolated from the nasal swabs of other calves showing pneumonia and M. alkalescense and M. bovis were isolated also from the nasal swabs of newly introduced animals after the outbreak of pneumonia. Eleven and 15 isolates of M. alkalescense and M. bovis, respectively, were sensitive to tiamulin, josamycin, lincomycin while resistant to erythromycin. Calves with pneumonia or those newly introduced showed low antibody titers to bovine herpesvirus type 1, parainfluenza virus type 3, bovine adenovirus type 7 and bovine respiratory syncytial virus.

    After adding ultrasonicated extract from Bordetella bronchiseptica (phase I) into the cell culture from the calf costal cartilage, cytotoxic effect was apparently observed, while no such effect was seen on the other four established cell lines treated with the extract. The same bacterial extract produced necrotic lesions after intracutaneous injection into guinea pigs, and it was inactivated by heating at 56° for 10 min.

    Ultrasonography and gross findings of the teats from 25 lactating cows and those from 24 mammas from culled cows were compared by the water bath dipping method. The normal teats showed hyperechogenic images of the epidermal wall, intima and rosette of Furstenberg, while the muscle layer was hypoechogenic and the teat sinus and canal appeared anechogenic. In heifes, the teat sinus appeared as a thin anechogenic area, and the teat intima was unclear in dry cows. Abnormal ultrasonographic fiindings were obtained in cases of the obstruction of teat sinus, intima hypertrophy, abscesses and polypes, which were morphologically confirmed. In lactating cows, some abnormal teats were detected by ultrasonography as diverticulum, stenosis and malformation.

    Nutritional states and occurrence of periparturient diseases as well as reproductive performance were studied in 178 high producing Holstein-Friesian cows. Cows in over-condition at drying off and those showing decreased body condition score (BCS) or lower serum concentration of total cholesterol during dry-period, manifested significantly higher incidences of postparturient diseases. The first insemination conception rate was significantly lower in cows showing a markedly decreased BCS during early-to mid-lactation period. Hematocrit, serum albumin and milk protein lowered remarkably in those with lowered BCS during earlyto mid-lactation periods. These results indicated that monitoring of BCS during a period from drying-off to early-and mid-lactation might be a useful tool for effective prevention of periparturient diseases and infertility in dairy cows.

    Plasmacytic ulcerative stomatitis (PUS) was observed in 5 of 14 cats having antibody to feline immunodeficiency virus. All the cats showing AIDS-related complex syndrome had PUS, while eosinophilic granuloma in only one case. In the PUS cases plasmacytosis was also seen in the regional lymph nodes.

    Detection of anti-canine parvovirus antibodies in dog sera were attempted by indirect enzyme-linked immunosorbent assay (ELISA) system using microplates coated with guinea pig polyclonal antibodies. As compared with haemagglutination inhibition (HI) test, the indirect ELISA showed higher sensitivity with titers correlated with those of HI test (r=0.78).

    A total of 692 rats, mostly Rattus rattus, which had been trapped in restaurants and food shops within the nine buildings of central Tokyo during a period from August 1988 to March 1990, were examined for Listeria spp. organisms in the large intestine contents. The organisms were detected from 133 of 692 (19.2%) samples, ranging from 9.0 to 44.8% depending on the buildings. L. monocytogenes and L. innocua were isolated from 60 (8.8%) and 73 (10.5%) rats, respectively. The perdominant serotypes of 60 isolates of L. monocytogenes were 4b (21 strains), 1/2b (20 strains), and 1/2a (14 strains).

    Actinobacillus pleuropneumoniae was isolated from 95 of 265 (35.8%) swine pneumonic cases at Nagoya city abattoir during a period from November 1989 to May 1992. Of the 95 isolates, 88 (92.6%), 4 (4.2%) and 3 (3.2%) were of serovars 2, 5 and 1, respectively. The serovar 2 was widely distributed in many farms, while the serovars 1 and 5 only in some limited farms. Six of 95 (6.3%) isolates, 1 of serovar 2, 3 of serovar 1 and 2 of serovar 5, were resistant to tetracycline or kanamycin of 11 test drugs.
