9例幼龄树驹的急性脊髓炎初报
幼龄树驹 急性脊髓炎
2008/3/13
两年来，在自繁的树鼩中发现9例急性脊髓炎。于出生后45—57天发病，病前幼晌发育良好。本病的主要特征是两后肢突然松弛性麻痹，脊髓胸段出血性坏死，并伴有体温急剧下降(35℃以下)、排便排尿障碍等症状。该病死亡率极高，似有传染性，但病因尚待进一步探讨。这是关养树鼩自发性急性脊髓炎的第一篇报告。
长江江豚感染铜绿假单胞菌肺炎的诊治
长江江豚 呼吸道疾病 铜绿假单胞菌 诊治
2007/12/21
本文记录了一例患急性铜绿假单胞菌肺炎的长江江豚诊断、治疗和预后观察过程。病原学鉴定采用鲜血琼脂平板对该江豚鼻腔拭子,在37℃ 下进行细菌需氧、厌氧培养和分离,并对所分离的细菌种类进行细菌学鉴定,结合血常规和血生化的检测结果,判定病原为铜绿假单胞菌(Pseudomonas aeruginosa, PA)。依据病原菌的药敏试验结果对患病江豚进行治疗,预后良好。通过对整个过程的资料分析以及预后观察,得到...
比较旋毛虫三个分离株对小鼠感染性和对阿苯达唑的敏感性。从幼虫囊包感染鼠肌肉的平均数量的差异，表明美国株(AM)对昆明株小鼠最易感，其次为黑龙江猪株(HP)，黑龙江犬株(HD)的感染性最低，三株的感染性有明显不同。从阿苯达唑损伤幼虫囊包的数量(%)差异，显示美国株对该药物最敏感，囊包幼虫的受损率(%)最高，黑龙江猪株对阿苯达唑的敏感性最低;提示旋毛虫对药物的敏感性差异，可作为其虫种或虫株的区分标准之...
可能以野生动物为病源的SARS的爆发和流行,使得人们更加关注野生动物传染性疾病对人类健康的威胁.特别是近30年来新出现的多种传染病,自然宿主几乎都是野生动物.本文就野生动物与人类的共患疾病做了简单的历史回顾.新的野生动物传染病的出现提示:如何避免和应对类似事件的再度发生或减少发生的频次、如何处理人与野生动物之间的关系等问题迫在眉睫,而解决这些问题的根本在于人类应该认识自身的位置,尊重自然和其它生命...
题目：感染松墨天牛的金龟子绿僵菌菌株的初步筛选
作者：何学友,陈顺立，黄金水
摘要：
松墨天牛是松材线虫病的主要媒介昆虫，本文对分离自松墨天牛的6株金龟子绿僵菌，以及从光肩星天牛、大蜡螟、伊藤厚丝角叶蜂和土蝽上分离的各1个菌株，共10个菌株的产孢情况、孢子萌发率进行研究；在此基础上选出金龟子绿僵菌1291、1349和2049三个菌株及球孢白僵菌F-263菌株，采用成虫跗节接种法和幼虫浸渍法进行室...
