The system has some ability to track cholera and flu, but it is particularly weak at “fingerprinting” antibiotic-resistant bacteria and linking hospital data.
这个系统有能力跟踪霍乱和流感，但是在指纹识别、耐药性细菌以及医院数据并网方面则是尤其的弱。
Using techniques similar to those involved in DNA fingerprinting, they then looked for the presence of antibiotic-resistant genes - and found these in high concentrations.
他们运用类似DNA指纹识别的技术，寻找抗药性的基因的存在，并在高浓度季铵盐存在下找到了它们。

At the same hearing, he says in one of the best studies used molecular fingerprinting to follow an outbreak of drug-resistant bacteria: "You actually can trace the specific bacteria around and they find that the resistant strains in humans match the resistant strains in the animals."
Now something similar to this is the basis of DNA fingerprinting, that's described in one of the boxes in your book.
与之机制类似的就是DNA指纹图谱法,这在你书上的方框里有解释

Fingerprints are marks made by a person's fingers which show the lines on the skin. Everyone's fingerprints are different, so they can be used to identify criminals.
If the police take someone's fingerprints, they make that person press their fingers onto a pad covered with ink, and then onto paper, so that they know what that person's fingerprints look like.
