| 摘 要： | 本研究旨在观察不同禽源贝氏隐孢子虫(Cryptosporidium baileyi)对鹌鹑的致病性差异。采用光镜、扫描电镜等技术研究了鸡源、鸭源、鹌鹑源、白文鸟源、鸵鸟源贝氏隐孢子虫分离株对10日龄鹌鹑的致病性。结果表明,感染鹌鹑均出现腹泻和呼吸道症状,排卵囊持续期11~18 d,虫体寄生于喉头、气管、法氏囊和泄殖腔。其中鸭源C.baileyi感染组鹌鹑发病率和死亡率分别为82.5%、25%,鸡源C.baileyi(郑州株)感染组发病率和死亡率分别为77.5%、12.5%,鹌鹑源C.baileyi感染组发病率、死亡率分别为37.5%和17.5%。本研究结果提示,不同禽源C.baileyi对鹌鹑有一定致病性,其致病性强弱存在差异。

| Abstract: | This experiment was conducted to explore the pathogenicity variance of Cryptosporidium baileyi isolates derived from different poultry hosts in quails.The chicken-derived,duck-derived,quail-derived,White Java sparrow-derived,and ostrich-derived C.baileyi isolates were inoculated to 10-day-old quails respectively and the pathogenicity was observed by microscopy and scanning electron microscopy(SEM) techniques.Diarrhea and the symptom of respiratory passage were shown,and the patent period of oocyst shedding ... |
