Finally, it needs iron to thrive and replicate, so it produces a siderophore, which is a term used for a group of small, high-affinity, iron chelating compounds that snatch iron from host cells.

最后，它需要人体内的铁元素来繁殖，所以它形成一种“铁载体”；铁载体是指微生物合成并分泌的螯合铁的、用于摄取铁元素的低分子量化合物，他们可以与宿主细胞竞争铁元素。

It has a bunch of virulence factors such as capsule, LPS, pili, and a siderophore, which helps the bacteria to attack and destroy the host cells and evade the immune system.

它具有多种毒力因子，如荚膜、脂多糖、菌毛以及铁载体；铁载体帮助细菌攻击宿主，破坏机体细胞，并逃避人体免疫。
