双壳类滤食性软体动物从环境水中去除悬浮的细菌，并将它们与假粪便一起沉淀，或者摄取和消化它们。根据水的细菌污染和已知的抽水率，积累通常超过预期水平一个数量级。这并不反映双壳贝类的高摄取效率，而是消化过程分离细菌簇的功能，从而增加了多个tue估计值和平板计数的接种位点。吸收率是物种特异性和温度依赖性，并显示与环境细菌负荷的相关性很小。消除也具有物种特异性和可变性。
Bivalve filter feeding mollusks remove suspended bacteria from the ambient water and either sediment them with the pseudofaeces, or ingest and digest them. On the basis of bacterial contamination of water and known pumping rate, accumulations usually exceed expected levels by an order of magnitude. This does not reflect high uptake efficiency of the bivalve, but is a function of the digestive process separating bacterial clusters, thereby increasing inoculation loci both for multiple tue estimates and plate counts. Uptake rates are species specific and temperature dependent and show little correlation with the ambient bacterial loading. Elimination is also species specific and variable.
