Summary Mice and rats failed to develop rabies after eating brains and carcases of rabid mice. Mice and rats failed to become infected
during contact with rabid mice and rats respectively.
It would appear from these observations that mice and rats are not important in the transmission of rabies.
Sumario Ratones y ratas fallaron de desarrollar rabia despues de haber comido cerebros y carcasas de ratones rabiosos. Ratones no se infectaron por contacto con ratones rabiosos. Los ratones no son importantes en la transmission de la rabia.
Résumé Des rats et des souris ne contractèrent pas la rage après avoir mangé des cerveaux et des carcasses de souris rabiques. Des souris ne furent pas infectées pendant leur cohabitation avec des souris rabiques. Les souris et les rats ne jouent pas un r?le important dans la transmission de la rage.相似文献

鸡球虫病防治药物的合理使用和药效评价 总被引:2,自引:0,他引:2

采用人工接种孢子化球虫卵囊的方法感染鸡球虫病,分别用抗球虫指数(ACI)法和治疗效果来评价克迪球和绿必达预防和治疗鸡球虫病的药效。结果表明,克迪球的ACI值大于200,能完全预防鸡人工感染球虫卵囊下球虫病发生,并显著提高增重率;绿必达作为预防用药无预防作用;但用作治疗使用时,治愈率100%,治疗效果优异。结果提示,对鸡球虫病防治药物的药效评价不能仅用ACI值法,而应进行综合评定。 相似文献

Cylindrical rumen boluses of a size (55 mm length x 18 mm diameter, density 2.9 g cm(-3)) appropriate for ruminating calves over 75 kg liveweight were constructed. The mean daily nutrient releases from two rumen boluses measured in rumen-cannulated cows were 62 mg Cu, 0.56 mg Se, 1.08 mg Co, 1.14 mg I, 38 mg Mn and 55 mg Zn with vitamins 3140 IU A, 628 IU D3 and 9 IU E. In a 123-day experiment with housed dairy calves given hay and a barley/soyabean meal mix, administration of two rumen boluses significantly increased plasma copper and blood glutathione peroxidase levels compared with unsupplemented control calves. There were similarly significant responses in a 143-day experiment with suckled beef-cross calves treated with two rumen boluses at grass. In both circumstances the basic diets provided inadequate allowances of both copper and selenium. 相似文献

重金属对鱼类的危害及污染防治 总被引:8,自引:0,他引:8
水产动物重金属污染问题 ,在世界范围来说是一个较普遍的食品卫生问题。如加拿大、美国、日本因河流被污染 ,大量鱼、贝类的汞含量超过规定指标。诸如此类问题 ,给人类带来了严重危害。淡水鱼类重金属污染问题情况很复杂 ,污染的有毒化学物质种类繁多 ,涉及的范围很广泛 ,常见的有汞、砷、铅、铬、镉等 ,其中砷属于非金属 ,但常将其纳入重金属类加以考虑。1 有毒金属的主要来源水产动物污染有毒金属的主要来源可分为外源性和内源性 (生物富集 ) ,外源性污染来源包括饲料、水质、底泥、空气、药物等。1 1 饲料中有毒化学物质的污染 在现… 相似文献

The purpose of this study was to examine the feasibility of a combination chemotherapy protocol ("CYCLONE") in cats, utilizing mitoxantrone and cyclophosphamide. Three normal adult cats were administered mitoxantrone (6.5 mg/m2 intravenously) and cyclophosphamide (100 mg/m2 intravenously) every 21 days for a total of three doses. Individual white blood cell count nadirs (range, 2.0-9.5 x 10(9)/L) and neutrophil count nadirs (range, 0.3 to 5.0 x 10(9)/L) occurred between days 2 and 10 after each dose of chemotherapy. Mean white blood cell count nadirs (range of mean, 5.5 to 8.4 x 10(9)/L) occurred between days 6 and 8, as did the mean neutrophil count nadir (range of mean, 1.7-4.0 x 10(9)/L). Side effects were limited to transient appetite suppression in one cat and loose stools in two cats. Myelosuppression and gastrointestinal side effects were comparable to those observed with single-agent mitoxantrone protocols. Further investigation of this protocol is warranted. 相似文献

青贮饲料调制与使用技术
秋季是作物收获的季节,也是牧草、青草成熟收获的季节,为饲料青贮提供了充足的原料来源.青饲料经乳酸菌发酵制成的柔软多汁、气味芳香、适口性强、营养丰富、耐贮藏的青贮饲料,基本上能保持青绿饲料的各种特性.这样,这既延长了饲料保存期限,又扩大了饲料来源,是值得大力推广的一项饲料调制技术。 相似文献

Subtext is the spirit of actor's lines, and it is a must in performance. As a consequence, subtext is important in both performance and actor's lines. This paper will give subtext a comprehensive analysis and discussion in four sections, say, what subtext is, the significance and function of subtext, how to discover subtext and how to express subtext. 相似文献

When preparations containing smooth Brucella abortus lipopolysaccharide (LPS) were used as antigens in an ELISA, strong positive reactions were obtained with sera from sheep infected with Brucella melitensis or with Brucella ovis. Oxidation of the LPS with sodium metaperiodate greatly reduced the extent of the cross-reactions with antisera to B. ovis, with little effect on the reactions with antisera to smooth B. melitensis. Periodate oxidation of hot saline extract (HSX) antigen of B. ovis markedly reduced its reactivity in ELISA with anti-B. ovis sera and eliminated cross-reactivity with anti-B. melitensis sera. The reactivity of HSX was maintained after treatment with proteinase K.
A simple ELISA system, in which replicate samples from a single serum dilution were tested in parallel against both B. ovis HSX antigen and periodate-oxidised smooth phase B. abortus LPS, was evaluated. It was found to discriminate well between antibodies induced by vaccination or virulent infection with B. melitensis strains and those induced by infection with B. ovis. 相似文献
