溴氰菊酯、敌百虫对山羊草蜱的疗效比较

草蜱(血蜱)为节肢动物门,蜘蛛纲,蜱螨目,蜱亚目,硬蜱科,血蜱属。虫体无头、胸和腹之分,外型呈椭园形,背腰扁平,假头在身体的前部,成虫有四对足。草蜱寄生在山羊体表吸血,是很多孢子虫的传播者。发育成熟的雌虫在草地或石缝中产卵。在温度、湿度适宜条件下孵化出幼虫、蜕变成若虫,在野草或灌木上爬行,山羊在放牧时被侵害。

草蜱叮咬致游走性红斑2例

1病例报告例 1，男，32岁，珠海市人。2004年7月6日来诊，自诉4月一天在钓鱼时被虫子（草蜱）叮咬小腿，次日发热，出现红斑，周身及关节痛。某医院按过敏和痛风治疗，病情发展。体检：颈项、腋下、小腿内侧、委中周围，均有环状红斑。少数红斑中心凹陷呈脓疮；多数红斑演变为陈旧性紫斑脱屑状，有的变石硬，关节明显肿胀，疼痛，活动加剧。舌苔黄，质紫红，舌边齿痕，脉洪且缓，素有胃脘不舒。体温37．5℃。治法：石膏60克、知母10克、甘草9克、元参9克、青黛6克、丹皮10克、二花15克、黄连6克，忍冬藤、青风藤、神曲、土茯苓、生地、大青叶、苡米各30克，大黄10克（后下），每日一剂，共七剂，水煎服，后疼痛消失、红斑面积缩小、色淡收敛，病情明显好转。又在上药方的基础上去青黛，减石膏、大青叶、土茯苓、神曲各半，加鸡血藤、丹参、黄芪、扁豆、白芷，共七剂，水煎服，后关节肿胀、痛疼和红斑均消失，病情基本恢复。但为巩固疗效，再续用上药方加减七剂后，完全康复，半年随访无复发。

甘肃省马驽巴贝斯虫病综合防治研究

在查明了 30余年来流行于甘肃省陇东南地区的一种马病病原为驽巴贝斯虫 ,传媒为森林革蜱和草原革蜱的基础上 ,开展了综合防治研究工作。通过抗血液原虫药物的治疗试验 ,证明咪唑苯脲、贝尼尔、黄色素、焦虫净对驽巴贝斯虫病的治愈率分别为10 0 %、84.6 2 %、81.82 %、73.33%。对贝尼尔用药途径改肌注为静脉滴注后治愈率由 84.6 2 %提高到 90 .6 3% ,且副反应大幅度降低。药物预防试验中证明咪唑苯脲、焦虫净、贝尼尔预防效果均达 98%以上 ,有效保护期分别为 5 9、2 4、12天。应用敌杀死灭蜱预防 ,效果达 10 0 % ,有效保护期为 2 3天。成功地研制出了咪唑苯脲缓释剂 ,其预防效果达 10 0 % ,有效保护期为 113天。研究制定了“三双”综合防治措施 ,在流行区 15个县 (区 )实施 3年 ,共治愈马类家畜 119175匹 ,预防马类家畜90 5 2 0 0匹。流行区发病率由 13.85 %降到 0 .0 9% ,死亡率由 5 .6 5 %降到 0 .0 4%。获得经济效益 890 8.98万元。

Interactions Ticks, Hosts and Pastures： Case of the Girolando Dairy Cattle and the Artificial Pastures of Panicum maximum and Panicurn maximum var. C1

On the Kpinnou ranch in Benin, it was observed that the Girolando dairy cattle which graze Panieum maximum var. CI are more susceptible to infestation of ticks. The purpose of this study was to highlight the interactions between ticks and their bovine hosts and two types of artificial grazing pastures. Nineteen young Girolando dairy cattle were used during the big rainy season （March-June） 2009. All present ticks on the animals have been counted according to the body region. The bovine have been divided into two relatively homogeneous groups often and nine animals. The group I of 10 animals had been grazed on Panicum maximum whereas the group 2 of 9 animals had been grazed on Panicum maximum var. C 1. During the two months of grazing, a weekly monitoring of the evolution of the load in ticks has been achieved. Four genera of ticks were identified on the bovine Girolandos （Amblyomma, Hyalomma, Rhipicephalus and Boophilus）. The Boophilus genus is the most abundant （P 〈 0.05）. The animals having grazed Panicum maximum var. C I are more infested than those that have been grazed Panicum maximum. A variation of the rate of infestation of the animals has been observed in relation to the different body areas. The colour of the coat also has an effect on the load in tick of the bovine. The bovine of dark coat are in general more infested （P 〈 0.05） than those of clear colour.
