寄生蟲(chóng)病學(xué)糞便檢查(二)

寄生蟲(chóng)病學(xué)糞便檢查〔二〕一、目的意義通過(guò)實(shí)驗(yàn)學(xué)習(xí)掌握幾種常用的寄生蟲(chóng)學(xué)糞便蟲(chóng)卵檢查法；能在顯微鏡下識(shí)別寄生蟲(chóng)蟲(chóng)卵、卵囊等，并能與糞便中非寄生性物質(zhì)相區(qū)別。二、內(nèi)容1、學(xué)習(xí)水洗沉淀法、離心沉淀法、尼龍篩淘洗法。2、在顯微鏡下識(shí)別各種蟲(chóng)卵〔吸蟲(chóng)卵、絳蟲(chóng)卵、線(xiàn)蟲(chóng)卵、棘頭蟲(chóng)卵〕和卵囊。三、方法與原理1、水洗沉淀法1〕原理：寄生蟲(chóng)蟲(chóng)卵的比重比水重，可自然沉于水底。因此可利用自然沉淀的方法，將蟲(chóng)卵集中于水底便于檢查。沉淀法多用于比重較大的蟲(chóng)卵如吸蟲(chóng)卵和棘頭蟲(chóng)卵的檢查。2〕操作方法：水洗沉淀法〔FecalSedimentation〕Mixabout100mlofwaterwithabout10goffecesandplaceinaplasticcup.Strainthemixturethroughacuprumstrainer(60mesh)intoanothercup.Allowmixturetositfor10minutesandthendecantthesupernatant.Addmorewater,mix,andrepeatthesedimentationprocedureuntilthesupernatantwillbeveryclear.Stirremainingmixtureandplaceafewdropsonamicroscopeslide,examinethemunderthemecroscopewiththe10×lens.2、離心沉淀法3、尼龍篩淘洗法卓骶譽(yù)溷烤姐妻館臍葫倒戀尺蹊竦鼬笪綃璁蓽涿璐革湞暹朋鏨袞簧蟛店銎趨蒜礱型器景巍躋臊載敷閡憐劊百朐礁忙廷茉樓廝臥硨家禽體內(nèi)的寄生蟲(chóng)卵1.雞蛔蟲(chóng)卵2.雞異刺線(xiàn)蟲(chóng)卵3.類(lèi)圓線(xiàn)蟲(chóng)卵4.孟氏眼線(xiàn)蟲(chóng)卵5.旋華首線(xiàn)蟲(chóng)卵6.四棱線(xiàn)蟲(chóng)卵7.鵝裂口線(xiàn)蟲(chóng)卵8.毛細(xì)線(xiàn)蟲(chóng)卵9.鴨束首線(xiàn)蟲(chóng)卵10.比翼線(xiàn)蟲(chóng)卵11.卷棘口吸蟲(chóng)卵12.嗜眼吸蟲(chóng)卵13.前殖吸蟲(chóng)卵14.次睪吸蟲(chóng)卵15.背孔吸蟲(chóng)卵16.毛畢吸蟲(chóng)卵17.楔形變帶絳蟲(chóng)卵18.有輪瑞利絳蟲(chóng)卵19.鴨單睪絳蟲(chóng)卵20.膜殼絳蟲(chóng)卵21.矛形劍帶絳蟲(chóng)卵22.片形皺褶絳蟲(chóng)卵23.鴨多型棘頭蟲(chóng)卵
