【摘要】：為建立在臨床樣本能夠同時檢測豬種、牛種、羊種、綿羊種布魯菌的多重PCR方法,根據(jù)NCBI已收錄的布魯菌全基因,設(shè)計并合成4對特異性引物,通過優(yōu)化多重PCR的反應(yīng)條件,建立能夠同時檢測4種布魯菌的多重PCR診斷方法。特異性試驗結(jié)果表明,可以從4種布魯菌以及4種細菌混合物中擴增出大小分別為276、494、733和976bp的特異性條帶,對照組的檢測結(jié)果為陰性;敏感性試驗結(jié)果表明,對4種病原菌基因組DNA的檢出量為豬種32.2pg、牛種21.3pg、羊種27.5pg、綿羊種43.2pg;人工模擬感染樣本檢測結(jié)果表明,能從混合感染的病料中特異地檢測出4種病原菌。應(yīng)用該方法對200份臨床奶山羊乳樣進行檢測,結(jié)果檢出4份陽性。建立的多重PCR方法具有特異性強、敏感度高、穩(wěn)定性好的特點,可以有效地檢測4種布魯菌的感染。
[Abstract]:In order to establish a multiplex PCR method for simultaneous detection of brucellosis in swine, cattle, sheep and sheep in clinical samples, four pairs of specific primers were designed and synthesized according to the whole genes of Brucella collected by NCBI, and the reaction conditions of multiplex PCR were optimized. A multiplex PCR method for simultaneous detection of four Brucella species was established. The specific bands of 276494733 and 976bp could be amplified from four Brucella species and four bacterial mixtures, respectively. The results of the control group were negative, and the sensitivity test showed that the specific bands could be amplified from the four Brucella species and the four bacterial mixtures. The amount of genomic DNA of four pathogens was 32.2pg for pigs, 21.3pg for cattle, 27.5pg for sheep and 43.2pg for sheep. The method was used to detect 200 milk samples of clinical dairy goats and 4 samples were positive. The multiplex PCR method has the characteristics of high specificity, high sensitivity and good stability. It can be used to detect the infection of four Brucella species effectively.
