1、石河子大學(xué)動(dòng)物科技學(xué)院本科畢業(yè)論文墾區(qū)豬肺炎支原體P97基因的檢測(cè)院（系）：動(dòng)物科技學(xué)院專(zhuān)業(yè)：動(dòng)物醫(yī)學(xué)學(xué)號(hào)：2010513200姓名：張延浩指導(dǎo)教師：李劭（副教授）石河子2014.6為了解石河子墾區(qū)豬肺炎支原體P97基因的遺傳變異情況，采集石河子部分規(guī)模化豬場(chǎng)的豬支原體肺炎疑似病料，采用PCR方法對(duì)疑似病料進(jìn)行了黏附基因P97的檢測(cè)，將PCR產(chǎn)物測(cè)序并與Genbank已登錄的標(biāo)準(zhǔn)菌株序列進(jìn)行同源性分析。結(jié)果顯示：75份病變肺臟中，陽(yáng)性病料43份,陽(yáng)性率為57.33%(43/75),P97基因序列與參考菌株的同源性為9
2、8.4%?99.2%。檢測(cè)結(jié)果表明石河子墾區(qū)豬支原體肺炎的感染情況比較嚴(yán)重，豬肺炎支原體流行株與國(guó)際標(biāo)準(zhǔn)菌株有很高的同源性。關(guān)鍵詞:豬肺炎支原體；P97基因；PCR檢測(cè)AbstractThecurrentsituationofprevalenceofMycoplasmahyopneumoniae(Mhp)anditscorrespondinggeneticvariationsofP97geneinsomelarge-scaledpigfarmsinthereclamationareaofShiheziwasmeasu
