与特定的细菌被发现在动物组织1-5。这种细菌主机协会（共生）可能是有害的（致病性），有没有健身的后果（共生），或有利于（互惠）。而备受人们关注已给病原相互作用，知之甚少的进程决定的有利/共生细菌的环境重现收购。轻器官之间的海洋革兰氏阴性菌共生五鲵和夏威夷短尾鱿鱼，E. scolopes，代表着一个非常具体的互动，其中一台主机（E. scolopes）建立贯穿其一生当然6,7只有一个菌种（ 五鲵 ）的共生关系。由五，生产发光鲵在这种互动提供了一个五反掠夺利益在8,9夜间活动scolopes，而营养丰富的宿主组织提供V。鲵与受保护的利基10。在每个主机上一代，这一关系的概括，从而较可预测的过程，可以在共生发展的各个阶段的详细评估。少年鱿鱼孵化aposymbiotically（uncolonized），并在实验室中，如果前30-60分钟内收集和转移到共生的自由水，不能被殖民除实验接种6。因此，这种互动提供了一个有用的模型系统，在其中进行评估，导致从11,12环境的共生微生物的具体收购的各个步骤。 在这里，我们描述了一种方法来评估发生刚出时aposymbiotic 大肠杆菌殖民化的程度scolopes暴露（人造）海水中含有五。鲵。这个简单的实验说明接种，自然感染和恢复E.新生的光器官的细菌共生scolopes。护理提供一个一致的环境共生的发展过程中的动物，尤其是关于水质和轻线索。特征描述的共生人口的方法包括：（1）的细菌派生发光的测量，（2）直接菌落计数恢复共生。
