1·Bacteria can be transformed with DNA extracted from a bacterial virus rather than from another bacterium, a process known as transfection.
原核生物中，偶尔也用到transfection这个词，当细菌的转化过程中吸收的外源DNA是病毒DNA时就应该称此过程为转染。
2·Postmortem analysis showed the presence of an as yet unidentified virus, as well as evidence of a known bacterial toxin.
尸检分析显示存在一种尚未识别的病毒，以及一种已知细菌毒素的证据。
3·Postmortem analysis showed the presence of an as yet unidentified virus, as well as evidence of a know bacterial toxin.
尸检分析显示出存在一种未知的病毒，以及一种已知的有毒细菌的证据。
4·Most deaths are caused by bacterial lung infections that move in after the virus.
很多死亡是在病毒之后由肺部细菌感染引起的。
5·We are family: Scientists suspect that a large DNA-based virus took up residence inside a bacterial cell more than a billion years ago to create the first cell nucleus.
病毒跟我们是一家人：科学家认为，十多亿年前一个大的DNA病毒在细菌细胞内居住并形成了第一个细胞核。
6·Thiomersal is a compound used to prevent bacterial and fungal growth in some inactivated (in which the virus has been killed) vaccines provided to countries in multi-dose vials.
硫柳汞是一种化合物，用于抑制以多剂量瓶向各国提供的某些灭活(即病毒已经被杀死)疫苗中细菌和真菌的生长。
7·Enke had been diagnosed with a bacterial stomach virus several weeks ago and did not play for Hannover for two months, although he reappeared for Sunday's 2-2 draw with Hamburg.
数周前，恩克被诊断出患有细菌性肠胃炎，因此缺阵两个月，不过在上周日汉诺威2 - 2战平汉堡的比赛中，他又重新登场。
8·Thiomersal is a compound containing ethyl mercury used to prevent bacterial and fungal growth in inactivated (in which the virus has been killed) vaccines presented in multi-dose vials.
硫柳汞是一种含有乙基汞的化合物，用于防止细菌和真菌在以多剂量瓶提供的某些灭活(即病毒已经被杀死)疫苗中生长。
9·Bacterial infections in the pathogens distribution of infantile pneumonia was still relatively common, and respiratory virus, atypical infection should not be overlooked.
我国婴幼儿肺炎病原体分布仍以细菌感染多见，而呼吸道病毒、非典型菌感染亦不容忽视。
10·A competing theory is that a mutagenesis drug may eradicate a virus or bacterial population by reducing the fitness to negative values.
一个竞争性的理论是诱变药物通过降低对负面价值的适应性而根除病毒或细菌群体。
