Profiles of the genomic DNA of 104 strains ofT. equigenitalis isolated from brood mares with contagious equine metritis in Hokkaido during the breeding seasons from 1980 to 1993, as well as those of five strains (SS28, EQ56, EQ59, EQ70 and HH139) previously isolated in Japan were examined after restriction digestion and crossed-field gel electrophoresis.(More)
Twenty cases of craniopharyngiomas treated surgically between 1972 and 1979 have been studed neuro-ophthalmologically. The visual fields demonstrated asymetrical bitemporal hemianopsia, occasionally homonymous hemianopsia and central scotomas. The visual function was followed up for a period of one to 8 years after the operation. Improvement and retention(More)
Minimal inhibitory concentrations of 33 antimicrobial agents for Haemophilus somnus were determined by the agar dilution method. The tested H. somnus strains were highly susceptible to penicillin G, ampicillin, colistin, and novobiocin. They were not susceptible to spiramicin and sulfadimethoxine, and streptomycin-resistant strains were found.
Eight Beagle dogs were inoculated intrabronchially with 5×109 live, avirulent cells ofBordetella bronchiseptica L-414 strain (phase I cells) (B. bronchiseptica) to investigate the serum levels of their C-reactive protein, the white blood cell counts, the antibody responses toB. bronchiseptica in the sera and tracheal secretions, and the effects of(More)
The nature of the receptors for Bordetella bronchiseptica was investigated by using the in vitro adherence assay system. The results indicated that sialyl glycoconjugates acted as receptors on swine nasal mucosa. These results were obtained by two independent approaches: inhibition of epithelial cell adherence with sialic acid-containing compounds but not(More)
The fatigue phenomenon of grating visual acuity was examined in 36 patients with optic nerve disorders by means of a laser interferometric acuity device. The phenomenon was found in 6 of 36 cases even under a luminance corresponding to the Japanese standards of office illumination. This fact indicated that the patients suffered visual fatigue in their(More)
