Coagulase-positive bacteria, like Staph aureus, convert the soluble fibrinogen into sticky fibrin, which then visibly clumps up.

凝固酶阳性细菌（如金黄色葡萄球菌）能将可溶性纤维蛋白原转化为粘性纤维蛋白，从而出现肉眼可见的团聚现象。

With coagulase negative species, like Staph saprophyticus or Staph epidermidis, the fibrin doesn't clump up.

对于凝固酶阴性的细菌，例如腐生葡萄球菌或表皮葡萄球菌，纤维蛋白则不会结块。

Where they slow down they tend to clump up, too, so you see more cars and trucks in the jam.

在他们减速的地方，他们也倾向于挤在一起，所以你会看到更多的汽车和卡车处于堵塞状态之中。

Also, these dead clumped up cells in the tubule form a brown granular cast which will eventually get excreted in the urine.

此外，这些死亡的细胞聚集在肾小管，形成了棕色颗粒管型，最终将在尿中排出。

So, use a micro plane if you have one, it'll grate it super finely so that it doesn't clump up.

所以，如果你有微型飞机，请使用它，它会把它磨得很细，这样它就不会结块。
