食品伙伴网讯 据美国食品安全新闻网消息，美国堪萨斯州立大学研究人员已开发出肉牛中大肠杆菌的基因快速测试法。
该研究团队由4人组成，分比为一名生物医学研究生，一名诊断医学与病理学教授，两名分子生物学家。研究人员采用多聚酶链式反应快速检测了大肠杆菌O157：H7的4段基因。
部分原文报道如下：
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.”
