| Prevalence of bovine trypanosomosis was determined from a total of 203 blood samples collected from Butaleja district, eastern Uganda. All samples were examined by microhematocrit centrifuge test (MHC), PCR and ELISA. ELISA was performed in accordance with the OIE standard procedures using Trypanosoma brucei gambiense procyclic form crude antigens. PCR were utilized to identify the species and the subspecies of trypanosome. The overall prevalence of bovine African trypanosomosis was 8.9% by MHC, and 45.3% by the ELISA. Since substantial number (12 out of 18) of MHC positive samples were negative in the PCR tests, we could not conclude the most epidemic trypanosome species in the studied area. Nevertheless, the PCR results suggests that the most prevalent... |

| During the attempt to seek T. congolense species-specific diagnostic antigens, we discovered one cDNA clone (P74) encoding 74 kDa putative abc1 protein (p74) from T. congolense PCF cDNA library. It has been suggested that members of the abc1 family are novel chaperonins and essential for both the mitochondrial electron transfer in the bc 1 complex and the coenzyme Q biosynthesis. Although abc1 protein in yeast has a nuclear or mitochondrial subcellular location, neither nuclear localization signal nor mitochondrial targeting signal was found within p74. Northern blot analysis revealed that the transcription level of P74 mRNA in bloodstream form (BSF) cells were 4 times higher than that in procyclic form cells. Western blot analysis also indicated that p74... |

| The mRNA expression patterns of EGF, HB-EGF, Amphiregulin, EGF receptor, IGF-1, CSF-1, IL-1 alpha, IL-1 beta, IL-1 receptor type 1, IL-1 receptor antagonist, LIF, COX-1, COX-2, Mucin-1, calcitonin, and rat USAG-1 mouse homologue, all of which are involved in the process of conceptus implantation to the endometrium, were examined during the estrous cycle by means of real-time quantitative PCR. COX-2, HB-EGF, LIF, Mucin-1, CSF-1, IL-1 alpha, IL-1 beta, and IL-1 receptor antagonist were temporally regulated during the estrous cycle and highly expressed during the estrous stage. In the case of COX-1, EGF, IGF-1, and EGF receptor, the highest mRNA expression was during the diestrous stage. In contrast, the rat USAG-1 mouse homologue mRNA expression did not... |

| Theileria orientalis is a benign protozoan species that is widely distributed in Japan, yet sometimes causes serious economic losses in the livestock industry. In this study, we conducted a molecular survey based on genes encoding the major piroplasm surface protein (MPSP) and p23 for T. orientalis detected in cattle grazing in southern areas of Japan, consisting of 2 farms in Kumamoto prefecture (Aso and Kuma districts) and 3 farms in Okinawa prefecture (Ishigaki, Iriomote, and Yonaguni Islands). High prevalence rates of T. orientalis infection were shown in all the cattle populations using the diagnostic MPSP- and p23-PCR assays. Phylogenetic analyses revealed 4 MPSP genotypes and 3 p23 genotypes. Furthermore, MPSP genotype-specific PCR methods were... |

| This study evaluated the stability of LAMP reagents when stored at 25C and 37C, and also assessed its detection efficiency on different DNA template preparations. Accordingly, LAMP using reagents stored at 25C and 37C amplified DNA of in vitro cultured T. b. brucei (GUTat 3.1) from day 1 to day 15 of reagent storage. There were no significant differences (P>0.05) in detection sensitivity of LAMP among the reagents stored at 25C, 37C and –20C (recommended storage temperature). LAMP using the reagents stored at above-mentioned temperatures amplified serially diluted DNAs (genomic DNA extracted by phenol-chloroform method, FTA card and hemolysed blood) of T. b. gambiense (IL2343) with high sensitivity. Reactions were conducted on the reagents stored... |
