羊痒螨成虫的盐水和吐温萃取物对已经发展到活跃期的痒螨病绵羊有显著的保护效应,通过PCR扩增获得了羊痒螨的cDNA编码免疫原Pso01,试验证实绵羊痒螨保护性抗原的成分复杂。在该病诊断方面,应用改进的ELISA法诊断自然感染的羊痒螨病,其敏感性为93.7%,免疫组织化学研究表明,在感染后4d受损伤的皮肤中CD4^+和CD45RA^+细胞的数量显著增加,并且γδT细胞和树突状细胞的CD1b^+显著增加持续了8d。随着绵羊瘁螨cRNA表达文库的建立,为应用现代分子生物学技术开发抗绵羊瘁螨病的疫苗积累了有价值的资料,从而为应用免疫学方法防控绵羊瘁螨病展示了光明的前景。 相似文献

A female checkered giant cross rabbit (Oryctolagus cuniculus) was presented with skin lesions on the perineal region. The cutaneous lesions extended 2 cm from the vulva and perineal glands. They were moist and erythematous, with abundant greasy yellowish scabs. Skin scrapings from the lesions were mounted in Amman’s chloral-lactophenol on microscope slides and examined at ×10 and ×40 magnification. Numerous mites were observed and identified as Psoroptes cuniculi, a common causal agent of otitis externa in rabbits. The rabbit was treated successfully with ivermectin. This case of psoroptic mange is atypical owing to the perineal location, apparent absence of auricular lesions, and the lack of contagion despite close contact with several other rabbits. 相似文献

对疫区周围环境及隔离饲养条件下的绵羊,进行了痒螨病传播途径和方式的研究.结果表明,脱落在外界的病原在一段时间内对绵羊有侵袭的可能,传播可通过携带有病原脱落到外界的羊毛、皮屑及被其污染物而感染绵羊,但不是本病的主要传播途径;患羊的直接接触是导致本病感染发病的主要途径,且最初发病的多发点是臀部的最膨大处,占发病部位的90%以上,其次为背、腹侧.这种传播方式导致了寒冷季节绵羊密集接触而引发的全群迅速感染,使本病在初春、秋冬季节呈高发. 相似文献

试验选取某养鸡场鸡球虫病患病鸡120只,随机分为4组,每组30只,其中1组为阳性对照组(感染不给药组),另外3组分别选用磺胺喹噁啉、地克珠利和癸氧喹酯3种抗球虫药物进行治疗;另选健康鸡30只,作为健康对照组。连续给药5d,在第8天将150只鸡全部扑杀剖检,通过计算抗球虫指数(ACI)来判断药物对球虫病的治疗效果。结果显示,癸氧喹酯的抗球虫指数最高,为高效抗球虫药物;地克珠利居中,为中效抗球虫药物;磺胺喹噁啉抗球虫指数最低,为无效抗球虫药物。 相似文献

乳猪黄痢是初生乳猪的一种肠道急性高度致死性以拉黄色稀粪为临床特征的常见传染病。本病由一定血清型的致病性的大肠杆菌引起 ,据笔者对中山食出猪场等场进行调查以及本人在生产实践中观察获知 ,此病常见于 1周龄内的哺乳乳猪 ,尤以 1~ 3天龄最常见 ,且呈急性经过 ,7日龄以上乳猪极少发病。若患病用药不当或不及时将导致很快大批死亡 ,尤其是出生后 2 4小时内的乳猪死亡率更高 ,以后随日龄增大而发病减少。笔者在调查中了解到 ,各场在治疗此病时所用药物各异 ,用药时间长 ,但疗效并不十分理想。为此 ,笔者用氟哌酸、庆大霉素 +链霉素、庆… 相似文献

A study was conducted to determine the efficacy of albendazole after it had been withdrawn from use due to the development of resistant strains of nematodes about ten years ago. The study also aimed to determine the present efficacy of levamisole, which had been recommended to replace albendazole. On one farm, the sheep and goats were divided into two groups, one group of each serving as the untreated control, while the other was treated with levamisole. The sheep on the other farm were divided into three groups, one serving as the untreated control group, the second being treated with levamisole and the third being treated with albendazole. Faecal samples were collected one day before treatment, and again 10 days after treatment. Anthelmintic efficacy was determined by the faecal egg count reduction test. Ten days after treatment, the sheep treated with levamisole on the first farm had a 98% reduction in faecal egg count, with a 95% confidence limit of 76%. The goats on the same farm had a 97% reduction in faecal egg count, with a 95% lower confidence limit of 81%. At the second farm, 10 days after treatment, sheep treated with levamisole had a 99.4% reduction in faecal egg count, with a 95% lower confidence limit of 88.9%, whereas the sheep treated with albendazole only had a 59.4% reduction in faecal egg count, with a 95% lower confidence limit of –19.6%. The study indicated that the gastrointestinal nematodes of sheep at the Department of Animal Science and Production farm were still resistant to albendazole about ten years after this anthelmintic had been withdrawn from use. A reduced efficacy of levamisole was suspected. 相似文献
