| The controversial circumstances relating to the classification of the benign Theileria species from Japan, Australia and Britain, which are frequently referred to as T. sergenti/buffeli/orientalis group parasites, was reviewed. Our recent systematic comparisons suggest a possibility that the Japanese T. sergenti (minor piroplasm in common parlance) might be a new species and the Australian T. buffeli and British T. orientalis might belong to one and the same species. The necessity for the review of the genus name for these benign Theileria species was also briefly discussed after the morphological studies of their schizogony. |

| 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 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... |

| We examined the detailed cellular localization of the rhoptry-associated protein-1 (RAP-1) of Babesia bovis merozoites by the post-embedding method of immuno-electron microscopy (IEM) using the anti-RAP-1 monoclonal antibody (mAb) 1C1 in order to substantiate the result in our previous report by an indirect immunofluorescent antibody test and the pre-embedding method of IEM. RAP-1 slightly distributed only in cytoplasm of merozoites, especially around the nucleus, but not in the rhoptry organelle at an early stage after invasion into a red blood cell. Then, the RAP-1 was accumulated in the rhoptry organelle and was also found in the iRBC cytoplasm, which suggests that synthesis and release of RAP-1 may occur in the iRBC. Finally, the RAP-1 was found within... |

| Ornithodoros moubata was fed artificially through a parafilm membrane with two types of artificial meals. The first type was composed of bovine and horse red blood cells suspended in phosphate buffered saline or fetal bovine serum (FBS). The second type was composed of FBS alone. Engorgement and post engorgement survival rates of the ticks after feeding on the two types of meals were compared and analysed statistically. FBS was found to be superior to red blood cell meals. Eventually two batches of FBS from different manufacturers were used to feed the ticks through artificial membrane. Engorgement and post engorgement survival rates were again compared and analysed statistically. There was no significant difference between the two lots. Finally O. moubata... |

| Serum from a dog immunized with blood plasma from a B. gibsoni-infected dog, putatively containing secreted antigens, was used to screen a cDNA expression library. A novel gene encoding BgSA1 was identified from the isolated clones. The serum raised in mice immunized with the recombinant BgSA1 expressed in Escherichia coli could recognize a native parasite protein with a molecular mass of 59 kDa. Comparing with the previously established ELISA with recombinant P50 as antigen, the ELISA with recombinant BgSA1 as the antigen was more sensitive when they were used to detect field samples. Moreover, a sandwich ELISA with anti-BgSA1 antibodies could detect the circulating BgSA1 in a serial blood plasma from a dog experimentally infected with B. gibsoni. These... |
