Eudiaptomus gracilis is the most abundant member of the zooplankton, plays a key role in the food web of Lake Balaton (Hungary). In the present study the composition of bacterial communities of this copepod was investigated based on cultivation and molecular cloning. The cultivated bacterial strains from the gut homogenate samples of Eudiaptomus gracilis belonged to four different clades: Firmicutes, Actinobacteria, Bacteriodetes and Proteobacteria. Clone library showed high species diversity, Firmicutes, Actinobacteria, Proteobacteria, representatives of Deinococcus-Thermus lineage and Cyanobacteria were detected. The isolated strains were very effective in degradation of different biopolymers. Many of the detected bacteria are known as opportunistic human or fish pathogens (Pseudomonas spp., Aeromonas spp., Chryseobacterium sp. and Staphylococcus sp.).
优美真哲水蚤是浮游动物中最丰富的成员，在匈牙利巴拉顿湖的食物网中起着关键作用。在本研究中，基于培养和分子克隆技术，研究了这种桡足类动物的细菌群落组成。从优美真哲水蚤的肠道匀浆样本中培养的细菌菌株属于四个不同的类群：厚壁菌门、放线菌门、拟杆菌门和变形菌门。克隆文库显示出很高的物种多样性，检测到了厚壁菌门、放线菌门、变形菌门、代表 Deinococcus-Thermus 谱系和蓝细菌的菌株。分离出的菌株对不同生物聚合物的降解非常有效。许多检测到的细菌是已知的机会性人类或鱼类病原体（假单胞菌属、气单胞菌属、黄杆菌属和葡萄球菌属）。
