| 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... |

| An 11-year-old Holstein-Friesian cow exhibited anorexia and jaundice. A large mass was found in the liver during necropsy. Macroscopically, the mass was composed of dark red multilobular tissue and a centrally located abscess, which was connected to the hepatic duct. Histologically, the mass consisted of proliferation of small neoplastic cells and was demarcated from the hepatic parenchyma by a thick region of granulation tissue. The neoplastic cells were predominantly arranged in solid sheets, but they also formed blood-filled cancellous structures, and proliferating foci were seen around blood vessels. Periodic acid-Schiff reaction demonstrated that a fine basement membrane-like structure surrounded the neoplastic cells. Immunohistochemically, the... |

| Anaplasma marginale has been detected in the Philippines only by peripheral blood smear examination and serological methods. This study generally aimed to molecularly detect and characterize A. marginale in cattle and ticks in Cebu, Philippines. A total of 12 bovine blood samples and 60 Rhipicephalus (Boophilus) microplus ticks were collected on the Cebu Island in 2011. 16S rRNA-based screening-PCR and DNA sequencing revealed 8 cattle (66.7%) and 8 ticks (13.3%) to be positive for A. marginale, and 1 tick (1.7%) to be positive for A. centrale. Selected positive DNA samples were further characterized based on 16S rRNA (longer sequence), Msp5, Msp1α,gltA and groEL genes for phylogenetic analyses. Sequence identities of partial DNA fragments of A. marginale... |

| 5歳6カ月齢のホルスタイン種乳牛が鼻出血，眼球突出および黒色便を呈したため，地方病性牛白血病を疑った．し かし，生前の臨床検査では牛白血病の確定診断はできず，病理組織学的検査により鼻腔内骨肉腫と診断された．本症例では，明瞭な呼吸器症状や顔面の変形といった鼻腔内腫瘍を疑わせる所見が乏しく，生前診断が困難であった． Enzootic bovine leukosis was suspected in a Holstein cow aged 5-years and 6-months, as it displayed symptoms of epistaxis, proptosis, and melena. However, clinicopathological findings failed to confirm a diagnosis of bovine leukosis, and histopathological findings revealed a nasal osteosarcoma. As the case lacked typical findings of nasal tumor such as sneezing and facial deformity, a nasal tumor diagnosis would have been difficult. |

| 8カ月齢ホルスタイン種乳牛が起立不能を呈した.右下顎リンパ節相当部に腫瘤を認めたため，午白血病を疑い血液検査および針吸引細胞診を実施したが，確定診断に至らなかった.病理解剖においては，環椎および胸椎にも腫瘤が存在し脊髄を圧迫していた.病理組織学的に，腫瘍細胞はBLA-36抗原陽性であり，B細胞性リンパ腫と診断した. BLV抗体は陰性であった.これらのことから，本症例は非定型若齢牛の散発性牛白血病と考えられた. An 8-month-old Holstein heifer presented with difficulty in standing. Bovine leukosis was suspected because of the enlargement of the right mandibular lymph node; however，this could not be confirmed by fine needle aspiration of the lymph node and blood examination. A postmortem examination revealed that neoplastic masses compressed the spinal cord and nerves at the atlas and thoratic vertebra. A histopathological examination revealed the mass to be B-cell lymphoma based on BLA-36 positivity，but antibodies against bovine leukemia virus were not detected.... |

| 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... |

| 排尿異常を認める21カ月齢の褐毛和種フリーマーチン肥育牛が，臨床的に水腎症および腎不全と診断された. 病理学的検査において，泌尿生殖器の重度雄性化，腎膿瘍および尿路結石が明らかとなった. 本症例は異常な尿道形態から尿路感染症と尿石症を継発し，最終的に腎後性腎不全に陥ったまれなフリーマーチン症例である. A Japanese Brown freemartin (21 months old) was clinically diagnosed with hydroneprosis and renal failure. A pathological examination revealed severe masculinization of the urogenital organs， pyonephritis and urolithiasis. These findings suggested that it was a rare case of a freemartin with a post-renal failure and morphological anomaly of the urinary tract，complicated by a bacterial infection and urolithiasis. 一一一Keywords :fr eemartin，po st-renal failure，se vere masculinization |
