| To develop a vaccine against cryptosporidiosis in animals, we constructed recombinant pseudorabies virus (PrV), a member of the Herpesviridae Alphaherpesvirus subfamily, expressing an immunodominant surface protein p23 of Cryptosporidium parvum sporozoites. Because of the wide host range of PrV, it has the possibility as the vector to delivery the foreign genes to several species of animals containing experiment animal. In the recombinant constructed in this study, the p23 gene under the control of CAG promoter was integrated into the thymidine kinase (TK) gene of PRV. Antibody against p23 recognized p23 expressed in CPK cells infected with the recombinant, as the approximate 23 kDa specific band in Western blotting analysis. This study showed the... |

| A set of primers were designed according to the published sequence of the gene encoding a rhoptry protein of Babesia caballi, and used to amplify parasite DNA from the blood samples obtained from carrier horses by polymerase chain reaction（PCR）method．The PCR method was sensitive enough to detect parasite DNA from 2.5 μl blood sample with a parasitemia of 0.000001％. The PCR method was compared with fluorescent antibody test(IFAT) in order to evaluate the diagnosis effciency for B. caball infection in horses. Of 142 field samples from Mongolia, 28(20%) and 96(69%)samples were identified positively by PCR and IFAT, respectively. Although the sensitivity of PCR was lower than IFAT, it was noted that the 5 IFAT-negative samples were PCR-positive, suggesting... |

| To determine the distribution of Babesia gibsoni infection in dogs in the eastern part of Japan, an epidemiological survey of dogs suspected of having B. gibsoni infection was attempted using the polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). Thirty-five of 115 such dogs (30.4%) were positive by PCR and/or ELISA. The 35 positive dogs consisted of 28 Tosa dogs, 4 American Pit Bull Terriers, and 3 mongrel dogs in Aomori, Fukushima, Ibaraki, Gunma, Chiba, Tokyo, Kanagawa, and Nagano Prefectures. The positive dogs had a significantly lower rate of tick exposure and a higher rate of bites by other dogs. Twenty-two of 35 B. gibsoni-positive dogs were infected with hemoplasma, and the rate of infection was significantly higher than... |

| The present study was aimed to examine whether a 50-Hz electric field (EF) affects biological stress responses. Male C57BL/6J mice were exposed to either 50-Hz EF (45 kV/m) or given a sham exposure for 30 minutes per day for 1, 2 or 4 weeks and then either mock inoculated or inoculated with the protozoan parasite, Toxoplasma gondii (T. gondii) PLK strain. Survival rate was calculated in mice infected with T. gondii after exposure to EF and the serum antibody levels to heat shock protein 60 (Hsp-60), and mRNA levels for Hsp-60, IFN-γ and IL-12p35 in mouse peripheral leucocytes were determined. As a result, no statistically significant difference was found in survival rate between mice exposed to EF and those in the sham exposure group. When mice were... |

| Neospora caninum infection is an important disease affecting bovine and canine populations worldwide. The dense granule antigen 7 of N. caninum (NcGRA7) is considered to be an immunodominant antigen. In the present study, the gene encoding truncated NcGRA7 (NcGRA7t) lacking an N-terminal signal peptide was expressed in Escherichia coli, and its diagnostic potential in an enzyme-linked immunosorbent assay (ELISA) was evaluated. The ELISA could clearly discriminate between known N. caninum-positive and -negative sera from dogs. Serum samples randomly collected from dogs in Japan and China were examined for the diagnosis of neosporosis using the ELISA. Twenty-three of 135 samples (17.03%) and 9 of 95 (9.47%) samples from Japan and China, respectively, were... |
