犬瘟热的防治及控制措施近几年来,城乡养狗的数量不断增加,狗的传染病也随之频繁发生,尤以犬瘟热为主的病毒病,给人类健康和畜牧业发展带来极大危害。现将犬瘟热的发生与传播途径、诊断要点、防治措施做以阐述,以及当前对犬瘟热病应采取的控防措施,发表几点个人意见与建议。犬瘟热是犬科、鼬科和浣熊科动物的一种急性、热性传染病。病犬以呈双相热型、鼻炎、严重的消化道障碍以及呼吸道炎症等为主要特征。1病的发生和传播病原体为犬瘟热病毒,是副粘病毒科、麻疹病毒属的一个成员。病毒对高温和某些化学消毒药较敏感,100℃1分钟死亡。传播途径主要是健犬与病犬的直接接触,也可通过空气飞沫而经呼吸道传染,或通过污染的食物经消化道感染。诊断要点流行特点病的发生无明显的季节性,尤以寒冷季节(10月至翌年4月间)多发。临床特征病犬体温升高,呈双相热型;精神沉郁,有明显的卡他性鼻炎和结膜炎症状,鼻流水样分泌物,打喷嚏、咳嗽,有的出现肺炎症状。鼻镜干燥和有龟裂。眼睑肿胀,有脓性分泌物,后期可发生角膜溃疡。腹下和股内侧、耳壳等处皮肤上可能出现小红点、水肿及脓性丘疹。病犬常呕吐,起初大便干燥,不久下痢,粪便中常混有血液和气泡,少数病例可见足掌和鼻翼皮肤角化过度性病变。单纯犬瘟热病犬无特征性的病理变化。诊断时根据病犬的流行特点、临床症状,可作出初步诊断。防治措施定期预防接种:首免月龄,二免与首免隔15~21天,三免与二免隔21天,三次免疫后,以后每年免疫一次,每次的免疫剂量为2毫升,可获得一定的免疫效果。加强兽医卫生防疫措施:各养殖场尽量做到自繁自养,在本病流行季节,严禁将场外的犬带到场内。各家庭饲养的宠物犬加强饲养管理,尽量做到不带入疫区。及时隔离治疗:及时发现病犬,早期隔离治疗,预防继发感染。病的初期可肌内或皮下注射抗犬瘟热高免血清(或犬五联高免血清)或本病康复犬血清(或全血)。血清的用量应根据病情及犬体大小而定,通常使用5~10毫升/次,连续使用3~5天,可获得一定疗效。加强消毒:对犬舍、运动场应以各种消毒药,如百毒杀等进行彻底大消毒。2当前对犬瘟热病应采取的控防措施当前流行的犬病应引起政府的高度重视养犬数量的快速增加,给一些犬类疫病的发生、发展创造了有利的条件。为此,各级政府应加大犬病防治工作的力度,对犬类实行限养、禁养政策,认真贯彻“管”“免”“灭”的综合防治措施。集镇养犬实行圈养,乡村农户实行拴养或圈养;对狂犬病实行计划免疫,实施强制免疫;犬瘟热、犬传染性肝炎实行推荐免疫,并纳入地方动物疫病免疫计划;对无免疫证明犬和游荡的野犬实行扑杀,避免伤害感染人畜。各级动物防疫监督机构及乡镇兽医站要积极配合公安、工商等部门,做好犬类疫病的免疫接种工作。积极开展犬类疫病防治工作的规范化、制度化。认真做好几种犬类疫病的免疫接种工作积极开展犬类疫病的免疫接种,是防止犬类疫病发生的主要措施。目前,犬瘟热、犬病毒性肝炎、犬狂犬病、犬细小病毒病和副流感皆可通过注射疫苗来加以预防。最方便有效的方法注射五联苗,也可用单联苗。在进行免疫注射时要严格按照免疫操作要求进行,做到一畜一针头,严格消毒,确保免疫效果。对不接受免疫的群众,要做好思想工作,必要时可配合公安部门,为其强制实施免疫,切实保证狂犬病的免疫密度达到100%。广泛宣传,提高人们的自我防范意识犬类疫病的防治工作,牵涉到集镇和农村,由于其涉及面广,影响力大,操作不当可造成不良的社会影响。为此,各级政府和动物防疫监督机构,要认真宣传、普及犬类疫病菌的有关防疫技术知识,尽量做到家喻户晓,营造一个使广大群众都支持犬类疫病防治工作的良好氛围,使广大群众提高自我防范意识,以促进犬病防治工作的全面、正常的开展。加强监督检查,依法打击违法养犬行为各级动物防疫监督机构,应切实履行其法律、法规赋予的职责,开展运输、上市交易的检疫、免疫工作。同时打击犬病防治工作中的不法行为,

授之以鱼不如授之以渔!蛋卷是某大学国际贸易学系学生,很高兴能帮上你。其实有个很好的办法可以让你迅速拿到这样的文献。我们一般找中英文的文献和论文都是用这样的办法。上google,然后收索你要的作品名称或者重点词汇在后面加.pdf.例如 “犬瘟热 防治.pdf”或者“犬瘟热 防治.doc” 这样。你要找什么论文或者文献就重点词+.pdf 或者重点词+.doc 蛋卷用这个办法屡试不爽,你可以多找几篇,看看论文的架构和作者的思路,并且适当参考。希望蛋卷的回答对你有帮助。
