Genetic and Antigenic Characterization of Newly Isolated Bovine Toroviruses from Japanese Cattle

Autor: Mitsugu Shimizu, Shin-ichi Fukuyama, Shigeji Katayama, Katsuo Masubuchi, Toshihiro Ito, Nobutaka Okada

Publikováno v: Journal of Clinical Microbiology

Torovirus, a member of the Coronaviridae family, is a gastrointestinal infectious agent that has been identified in humans, cattle, pigs, and equines. Toroviruses, except equine torovirus, are difficult to propagate in cell culture; indeed, to date,

Epidemiological analysis of bovine torovirus in Japan

Autor: Toshihiro Ito, Nobutaka Okada, Shin-ichi Fukuyama

Publikováno v: Virus Research

Bovine torovirus (BToV), a member of the Coronaviridae family, is an established gastrointestinal infectious agent in cattle. No epidemiological research on BToV has been reported from Japan. In this study, we performed a survey to detect BToV in Jap

Bovine rotavirus G and P types and sequence analysis of the VP7 gene of two G8 bovine rotaviruses from Japan

Autor: Nobutaka Okada, Yuichi Matsumoto

Publikováno v: Veterinary Microbiology. 84:297-305

A total of 1481 fecal specimens were collected from diarrheic calves under 1 month of age on 29 dairy and beef farms in 11 prefectures in Japan during the period from 1987 to 2000. Those calves and their dams were not vaccinated against rotavirus. On

Publikováno v: Journal of Veterinary Medical Science. 61:827-830

Two pairs of PCR primers were designed to perform nested PCR targetting of a 540 bp fragment of the nucleocapsid (N) protein gene (N gene) of porcine epidemic diarrhea virus (PEDV). The N gene of PEDV was amplified with 4 PEDV strains and 11 small in

Influence of Cell Surface Glycoprotein gC Produced by Pseudorabies Virus on Cytopathic Effect

Autor: Toshiaki Ohgitani, Yukio Shimizu, Nobutaka Okada, Shigeji Katayama, Teruaki Kokubu

Publikováno v: Journal of Veterinary Medical Science. 60:905-909

The wild-type pseudorabies virus (WT-PRV) produced a round-type cytopathic effect (CPE) in PK-15 cell line of porcine kidney origin, while PRVgCs lacking in gC-transmembrane-anchor region and PRVgC-defecting in gC gene produced a syncytium-type CPE.

Autor: Osamu Sasaki, Satoshi Ui, Eiji Oishi, Katsuhiko Amimoto, Hisao Yasuhara, Hisae Nakamura, Nobutaka Okada, Takashi Kitajima

Publikováno v: Journal of Veterinary Medical Science. 60:9-14

A vaccine was prepared from a NaOH-extracted antigen of the Kyoto strain (serovar 2) of Erysipelothrix rhusiopathiae (E. rhusiopathiae) with an oil adjuvant, and was injected twice at 3-week intervals into SPF pigs and conventional pigs with maternal

The Protective Effect of Clostridium novyi Type B Alpha-Toxoid against Challenge with Spores in Guinea Pigs

Autor: Makoto Isogai, Takashi Kitajima, Hisao Yasuhara, Eiji Oishi, Osamu Sasaki, Nobutaka Okada, Katsuhiko Amimoto

Publikováno v: Journal of Veterinary Medical Science. 60:681-685

Clostridium novyi (C. novyi) Type B alpha-toxin was purified from culture supernatant by column chromatography, and was inactivated by formalin. A purified alpha-toxoid vaccine was prepared by mixing it with an aluminum phosphate gel adjuvant. Guinea
