We examine the management of livestock diseases from the producers‘ perspective, incorporating information and incentive asymmetries
between producers and regulators. Using a stochastic dynamic model, we examine responses to different policy options including
indemnity payments, subsidies to report at-risk animals, monitoring, and regulatory approaches to decreasing infection risks
when perverse incentives and multiple policies interact. This conceptual analysis illustrates the importance of designing
efficient combinations of regulatory and incentive-based policies.

海湾扇贝(Argopecten irradians Lamarck)"性腺萎缩症"的组织病理学研究 总被引:2,自引:0,他引:2
利用组织学与组织化学染色方法,在光镜下研究了患"性腺萎缩症"海湾扇贝的组织病理学变化.结果表明,患病贝生殖细胞肿胀或萎缩,发育滞后;消化盲囊、鳃等器官组织也呈现明显的病理学变化特征,主要表现为结构紊乱,细胞变形、脱落甚至溃散,血细胞增生,出现强嗜碱性包涵体等异常结构.组织化学研究显示消化盲囊及消化道中酸性磷酸酶、碱性磷酸酶含量下降;鳃、外套膜中多糖类物质含量增加等. 相似文献

Fungal Invasion of Massive Corals 总被引:2,自引:0,他引:2
Abstract. Five species of corals from the Andaman Islands in the Bay of Bengal (Indian Ocean) have been regularly found to have single or multiple necrotic patches. The occurrence of such corals with necrotic patches varied from 10–50% in the field. Sections revealed a septate dark brown mycelial fungus on the surface and subsurface of the dead patches in five coral species. The fungus was isolated in culture and identified as Scolecobasidium sp.
The fungus formed a distinct dense brown to black zone of 0.5-1.5 cm width immediately below the surface of the corals. In terms of biomass, the fungus was estimated to contribute 3–5 mg cm-3 of coral skeleton. 相似文献

对虾病原菌抑菌药物的研究 总被引:1,自引:0,他引:1
应用药敏纸片法研究了48种化学疗剂对中国对虾红腿病病原菌(包括Vibrio alg-inolyticus,V.campbellii,V.parahaemolyticus,Proteus vulgaris及未确定的海洋弧菌)生长的抑制作用,其中氯霉素(30μg/片)、磺胶药+TMP(25μg/片)和呋喃妥因(200μg/片)抑菌力最强、抑菌谱最广;红霉素(15iu/片)、土霉素(30μg/片)无明显抑菌作用。对27种中草药水浸液以平板点种法试抑菌作用。结果表明乌梅、石榴皮、五味子的水浸液具有较强的抑菌活性,可用于配制防病药物饵料。5,7—二氯-8-羟基喹啉对多种病原菌有较强的抑菌作用,药物平板点种法最小抑菌浓度为25mg/L,药浴法有效抑菌浓度低于5mg/L。 相似文献
