Particular chunks of its genome, called " pathogenicity islands" (or Sapis), seem to behave like genetic parasites; bits of DNA that replicate selfishly without regard for the well-being of their host.

基因组特定部分，称为“致病性岛”(或致病岛)，似乎表现得像是遗传寄生物; 这些DNA片段会自私地复，不顾宿主健康。

And embedded within Salmonella's genome are pathogenicity islands, clusters of adaptive genes that launch the next phase of attack.

沙门氏菌基因组中还包含致病性岛，即组适应性基因簇， 可启动攻击阶段。

But for most of this episode, especially for the pathogenicity part of things, I'm gonna focus on Candida albicans.

但在本节大部分内容中， 特别是关于致病性部分，我将重点关注白色念珠菌。
