【摘要】:為了快速檢測臨床上副豬嗜血桿菌(Haemophilus parasuis,Hps)感染,根據(jù)Gen Bank中Hps的16S rRNA基因保守區(qū)序列,設(shè)計(jì)1對(duì)特異性引物,利用PCR方法檢測Hps,并進(jìn)行特異性、敏感性及臨床檢測。結(jié)果顯示:PCR反應(yīng)選擇58℃為最適退火溫度,0.5μL(20μmol/L)為最適引物量,模板濃度為7.2×10~(-6)μg/mL時(shí)即可擴(kuò)增出814 bp特異性目的片段,與細(xì)菌分離結(jié)果一致。結(jié)果表明:該方法敏感、快速、特異,可用于臨床上Hps感染的快速檢測。
[Abstract]:In order to detect Haemophilus parasuis Hpss infection in clinic quickly, according to the 16s rRNA gene conserved region sequence of Hps in Gen Bank, a pair of specific primers were designed and detected by PCR method. Sensitivity and clinical test. The results showed that 814 BP specific target fragment could be amplified when the optimal annealing temperature was 58 鈩,
