The fate of bacteria in the food of a common freshwater invertebrate has been studied both in controlled laboratory experiments and in a stream sediment. The animal chosen was the larva of the burrowing mayfly,Ephemera danica. It ingested all available bacteria nonselectively. More bacteria were found associated with the hindgut than with the mesenteron despite continuous plug flow of food through the alimentary canal. Species of bacteria were affected in different ways.Aeromonas hydrophila andCitrobacter freundii were both digested, the former selectively.Flavobacterium sp. and other unidentified species appeared to attach to the hindgut wall. Digestion of bacteria was not due to a sudden change in pH.
已经在受控实验室实验和溪流沉积物中研究了常见淡水无脊椎动物食物中的细菌命运。选择的动物是挖掘蜉蝣的幼虫，Ephemera danica。它非选择性地摄取所有可用的细菌。尽管食物通过消化道连续塞流，但与肠系膜相比，后肠中发现的细菌更多。细菌种类受到不同的影响。气单胞菌和弗氏柠檬酸杆菌均被消化，前者具有选择性。黄杆菌属和其他未鉴定的物种似乎附着在后肠壁上。细菌的消化不是由于 pH 值的突然变化。
