A 2-year-old East Friesian sheep imported from Australia exhibited severe anemia after contagious pustular dermatitis in Hokkaido, Japan. Hemoplasma infection was confirmed in blood smears. Both Mycoplasma ovis and ‘Candidatus Mycoplasma haemovis’ were detected by PCR and sequence analyses. In the epidemiological analysis, dual pathogens were detected in 6 of 12 (50.0%) sheep imported from Australia with the infected ewe at the same time, 1 of 5 (20.0%) sheep introduced from a domestic farm in Hokkaido, and in 1 of 16 (6.3%) sheep from an epidemiologically unrelated ranch. It is the first clinical case of sheep to confirm coinfection of these pathogens in Japan.

The present study evaluated the effect of hemoplasmosis on cattle productivity. Prevalence of bovine hemoplasma was examined by polymerase chain reaction (PCR) using whole blood samples collected from 93 breeding cows and their 71 calves in Hokkaido, Japan. Monthly milk production records and other clinical data were compared between Mycoplasma wenyonii (Mw)-infected, “Candidatus Mycoplasma haemobos” (CMh)-infected, co-infected and PCR-negative groups. Blood chemical parameters were obtained from the 93 cows and 64 calves. PCR results showed that 89.2% (83/93) of cows and 14.1% (10/71) of calves were positive for bovine hemoplasma. Based on productivity data obtained from the 93 cows, Mw-infected, CMh-infected and co-infected cows had significantly lower...

10歳の雄の雑種犬が,3週間前から持続する発熱及び元気消失を主訴に帯広畜産大学動物医療センターを受診した.心雑音及び心エコー検査において僧帽弁の疣贅物が確認され,抗生物質等により加療したが,第7病日より心不全の悪化を認め,第10病日に肺水腫により斃死した.病理解剖では,軽度の心拡大及び僧帽弁における多中心性疣贅物が認められた.血液培養検査では,Staphylococcus haemolyticusが検出されたが,疣贅物を用いたPCR検査ではStreptococcus canisと100%一致する塩基配列が得られた.血液培養分離菌はコンタミネーションであった可能性が高く,本症例の心内膜炎はStreptococcus canisによるものと考えられた.血液培養結果と実際の心内膜炎起因菌が異なる場合があることを考慮する必要がある.

Overexpression of Interleukin 2 Receptor, Thymidine Kinase and Immunoglobulin-Associated Alpha-1 Messenger RNA in a Clinical Case of Enzootic Bovine Leukosis OAK
TAWFEEQ, Mohammad Monir; TAGAWA, Michihito; ITOH, Yuuki; SUGIMOTO, Kazuya; KOBAYASHI, Yoshiyasu; INOKUMA, Hisashi; 古林, 与志安; 猪熊, 壽.
A 49-month-old Holstein cow with anorexia, tachypnea, enlarged peripheral lymph nodes, and difficulty standing up was suspected of bovine leukosis. Hematological examination revealed lymphocytosis with the presence of neoplastic cells. Increased total lactate dehydrogenase (LDH) activity, isozymes of LDH-2 and LDH-3 activities and thymidine kinase activity were observed. Cytological findings of fine needle aspiration of subiliac lymph nodes indicated lymphosarcoma. Histopathology and antibody analysis confirmed the diagnosis of enzootic bovine leukosis, a B-cell bovine lymphoma caused by bovine leukemia virus. Gene expressions known as biomarkers of hematopoietic neoplasia in human were also examined in the present case. Increased messenger RNA expression...

Prevalence and Molecular Analyses of Hemotrophic Mycoplasma spp. (Hemoplasmas) Detected in Sika Deer (Cervus nippon yesoensis) in Japan OAK
TAGAWA, Michihito; MATSUMOTO, Kotaro; YOKOYAMA, Naoaki; INOKUMA, Hisashi; 松本, 高太郎; 横山, 直明; 猪熊, 壽.
Hemotropic mycoplasmas (hemoplasmas) are cell-wall deficient, epierythrocytic bacteria that cause infectious anemia in several mammalian species. The prevalence of hemoplasma species was examined by screening and species-specific PCR using blood samples collected from 51 sika deer in Hokkaido, Japan. Molecular analyses were performed for the 16S rRNA, 23S rRNA and RNase P RNA (rnpB) gene sequences. A total of 23/51 (45%) deer DNA samples were positive for hemoplasmas in the screening PCR. Using species-specific PCR, 12 and 17 samples were positive for ‘Candidatus Mycoplasma haemocervae’ and ‘Candidatus M. erythrocervae’, respectively. Sequencing and phylogenetic trees of those three genes indicate that the ‘Candidatus M. haemocervae’ and ‘Candidatus M....

Prevalence and Risk Factor Analysis of Bovine Hemoplasma Infection by Direct PCR in Eastern Hokkaido, Japan OAK
TAGAWA, Michihito; YBANEZ, Adrian P.; MATSUMOTO, Kotaro; YOKOYAMA, Naoaki; INOKUMA, Hisashi; 松本, 高太郎; 横山, 直明; 猪熊, 壽.
The prevalence and risk factors of 2 bovine hemoplasma species—Mycoplasma wenyonii (Mw) and “Candidatus Mycoplasma haemobos” (CMh)—were examined by direct PCR using whole blood samples collected from 343 cattle in Eastern Hokkaido, Japan. The sensitivity of the direct PCR assay was 10-fold higher than the standard PCR assay, detecting 5 copies of bovine hemoplasma DNA per reaction. An epidemiological survey of sampling location, living conditions, age and bovine leukemia virus antibody was performed to assess infection risk factors. The prevalence rates were 38.5% for Mw and 39.1% for CMh, respectively, with an overall prevalence rate of 64.7% for all bovine hemoplasma infections. Significant differences were found in sampling location, living conditions...
