食品伙伴網(wǎng)訊   據(jù)美國食品安全新聞網(wǎng)消息，美國堪薩斯州立大學(xué)研究人員已開發(fā)出肉牛中大腸桿菌的基因快速測試法。

    該研究團(tuán)隊由4人組成，分比為一名生物醫(yī)學(xué)研究生，一名診斷醫(yī)學(xué)與病理學(xué)教授，兩名分子生物學(xué)家。研究人員采用多聚酶鏈?zhǔn)椒磻?yīng)快速檢測了大腸桿菌O157：H7的4段基因。

    部分原文報道如下：

    Leading the project is Lance Noll, veterinary biomedical science graduate student; T.G. Nagaraja, university distinguished professor of diagnostic medicine and pathobiology, and Jianfa Bai, assistant professor in the KSU Veterinary Diagnostic Laboratory.

    To develop the diagnostic test, Noll and Nagaraja worked with two KSU molecular biologists: Bai and Xiaorong Shi, research assistant of diagnostic medicine and pathobiology.

    The new test is a molecular assay, or polymerase chain reaction, that has been developed and validated to detect and quantify four genes specific for E. coli O157:H7. It detects bacteria based on genetic sequence, which Nagaraja calls the “bacteria's fingerprints.”
