| Four new species of the genus Gasteruption Latreille, 1796 (Hymenoptera: Evanioidea: Gasteruptiidae: Gasteruptiinae) are reported from NW China: three from Shaanxi province and one from Ningxia province. The new species (G. bicoloratum Tan & van Achterberg, sp. n., G. huangshii Tan & van Achterberg, sp. n., G. pannuceum Tan & van Achterberg, sp. n., and G. shengi Tan & van Achterberg, sp. n.) and three newly recorded species (G. sinepunctatum Zhao, van Achterberg & Xu, 2012, G. boreale (Thomson, 1883) and G. oshimense Watanabe, 1924) are keyed and fully illustrated. In total, seven species are known from Shaanxi province, which is approximately half of the expected number. The East Palaearctic specimens provisionally identified as G.... |

| Background: Trypanosoma equiperdum causes dourine via sexual transmission in Equidae. T. equiperdum is classified under the subgenus Trypanozoon along with the T. brucei sspp. and T. evansi; however, the species classification of Trypanozoon remains a controversial topic due to the limited number of T. equiperdum reference strains. In addition, it is possible that some were misclassified T. evansi strains. Thus, there is a strong need for a new T. equiperdum strain directly isolated from the genital mucosa of a horse with a clinically-and parasitologically-confirmed dourine infection. Methods: Trypanosomes isolated from the urethral tract of a stallion with suspected dourine, were directly cultivated using soft agarose media at 37 degrees C in 5 % CO2. For... |

| Toxoplasma gondii matrix antigen 1 (TgMAG1), known as the 65-kDa protein, which is abundantly expressed in both bradyzoites and tachyzoites, was evaluated as a candidate for the development of a diagnostic reagent for ovine toxoplasmosis. The TgMAG1 gene was expressed in Escherichia coli as a fusion protein with glutathione S-transferase (GST),and the recombinant TgMAG1 (rTgMAG1) was tested in an enzyme-linked immunosorbent assay (ELISA). The ELISA with rTgMAG1 showed a highly specific reaction with sera from mice experimentally infected with T. gondii but not with the closely related Neospora caninum. The antibodies to TgMAG1 were detectable from the acute to the chronic infectious stages in a mouse model. A total of 175 serum samples collected from sheep... |

| Anaplasma marginale is an etiologic agent of bovine anaplasmosis. This study aimed to molecularly detect and characterize A. marginale that is prevalent in Mongolian cattle populations. A highly specific and sensitive nested PCR (nPCR) method based on the Msp5 gene was developed to detect A. marginale (Msp5 nPCR). The method detected A. marginale from the positive DNA samples obtained from different countries, while no amplicons were observed from DNA samples of several other bovine blood pathogens tested. The detection limit of Msp5 nPCR was determined to be 2 copies/μl. The method was tested against field blood DNA samples prepared from 300 Mongolian cattle in 2010. Results indicated a prevalence rate of 8.7% (26 of 300). On the other hand, partial DNA... |

| Babesia venatorum, formerly known as Babesia sp. EU1, is a zoonotic hemoprotozoan parasites that commonly infects deer. In the present study, we investigated B. venatorum infection in Ixodes persulcatus, an important tick vector capable of transmitting several tick-borne pathogens that cause babesiosis, encephalitis, tularemia, and Lyme diseases. DNA samples extracted from questing I. persulcatus ticks (n=63) that had been collected in Selenge province of Mongolia in 2012 and 2013 were screened for B. venatorum using a nested PCR assay. The findings showed that two of 63 DNA samples were positive for B. venatorum. The 18S rRNA sequences amplified from B. venatorum-positive DNA samples shared high identity scores (96.1–99.9%) with known B. venatorum... |

| Babesia ovata is a tick-transmitted hemoprotozoan parasite that infects cattle. In our study, bovine blood samples (n=2,034) were collected from 10 different countries (Brazil, China, Ghana, Japan, Mongolia, the Philippines, South Africa, Sri Lanka, Thailand and Vietnam) and DNA extracted. The DNA samples were screened using an established and specific polymerase chain reaction (PCR) assay targeting the Apical membrane antigen 1 (AMA-1) gene. Parasite DNA was detected among samples collected from Japan, Mongolia and Thailand. Sequence analyses confirmed that the PCR assay detected only B. ovata AMA-1, and that amplicons from different geographical locations were conserved. Our findings highlight the importance of designing adequate strategies to control B.... |

| Babesia microti is a tick-transmitted zoonotic hemoprotozoan parasite. In the present study, we investigated B. microti infection in questing ticks in Mongolia. A total of 219 questing ticks were collected from three different Mongolian provinces (Bayan-Olgii, Khovsgol, and Selenge). Of these, 63 from Selenge were identified as Ixodes persulcatus, while the remaining 156 (from all three provinces) were identified as Dermacentor nuttalli. When the tick DNA samples were screened using a B. microti-specific nested PCR, 19 (30.2%) of the 63 I. persulcatus ticks were found to be B. microti-positive. The parasite was not detected in D. nuttalli. Subsequently, the 18S rRNA, cox1, and tufA sequences of B. microti were amplified, sequenced, and subjected to... |
