ジャーナル フリーIn November, 1975, some adult sheep produced in Japan began to suffer from fever, anemia, palpitation, tachypnea, and hemoglobinuria. Light and electron microscopy revealed that many parasitic organism of Eperythrozoon ovis were present on the surface of erythrocytes. With an increase in parasitic rate, the erythrocyte count, hematocrit, and hemoglobin values decreased, erythrocytic resistance was reduced, and hemoglobin plasma appeared.
When a splenectomized and an intact sheep were inoculated with blood from a spontaneously infected sheep, Ep. ovis began to appear in their peripheral blood 10 and 12 days after inoculation, respectively. The inoculated sheep manifested the same clinical signs and hematological changes as the spontaneously infected one. This report was the first to confirm the presence of Ep. ovis in Japan.抄録全体を表示PDF形式でダウンロード (3622K) -

ジャーナル フリー牛肺虫汚染草地を夏期の一定期間休牧するかあるいは反転耕起方式によって更新した後, 健康牛を放牧して感染防止効果すなわち牛肺虫感染からみた草地の清浄化について試験を行なった.
汚染草地の1ヵ月間休牧では, 牛肺虫の感染を防止できなかった. 2ヵ月間の休牧では, 汚染程度が低かった草地で感染が防止されたものの, 汚染程度がやや高かった草地では感染程度は軽減したものの感染を防止し得なかった. 3ヵ月間の休牧によっても高度に汚染された草地では感染を防止できず, このような期間の夏期休牧では牛肺虫汚染草地を清浄化することが難かしいように思える.
汚染草地の更新によって本病の清浄化は可能と思われる.

ジャーナル フリーIn 1975, 39 young dairy cows were placed on an uncultivated grassland in Yamagata Prefecture for 5 days in August and 11 days in September. As a result, 29 cows died over a period from September 12 to October 2. They and severely affected cows manifested an increase in ascites, subcutaneous edema, low body temperature, abnormal cardiac function, low blood calcium level, high serum urea-nitrogen level, glycosuria, and aciduria. The dead cows presented an especially high urea-nitrogen level ranging from 186 to 281 mg/dl and indicating uremia induced by renal insufficiency. Histological changes were particularly remarkable in the kidney. In the uriniferous tubules, necrotic epithelial cells were shed and protein-like, hyaline, and crystalline substances present in the lumen. The amount of crystalline substance was much smaller than that reported in the case of oxalate poisoning. Hypoplasia of erythroblastic cells in the bone marrow was different from that observed in bracken poisoning. Such a bovine disease as affecting the kidney chiefly and exhibiting a high fatality was reported for the first time in Japan.抄録全体を表示PDF形式でダウンロード (2910K) -

ジャーナル フリーThe gel precipitin test and reticuloendotheliosis virus (REV) isolation were carried out with antigen of REV strain T on 309 chicken sera collected from 32 flocks in 1964-65 (group A) and on 430 chicken sera from 42 flocks in 1974-75 (group B). Positive results were obtained from 5.2% of the sera and 25.0 % of the flock of group A and 2.6% of the sera and 11.9% of the flock of group B. It was clarified that REV was present in Japan already in 1964. Antibody was positive in 32.9%, on the average, of the flocks surveyed.
In all the positive cases of the gel precipitin test, the precipitation line was completely agreeable with that of immune serum to REV strain T. These cases were also positive for the indirect fluorescent antibody technique.抄録全体を表示PDF形式でダウンロード (663K) -
