摘　　要：The peritrichs, Peritrich ciliates, are a large and distinctive group of ciliates,which are protozoans characterized by cilia and two kinds of nuclei, macronucleus and micronucleus. Traditionally, they have been subdivided into the Orders Sessilida and Mobilida according to morphological characters. Recent molecular studies by a research team at the CAS Institute of Hydrobiology （IHB） will help people to gain insight into the evolutionary relationship of the group. Their work entitled ＂Reevaluation of the phylogenetic relationships between mobiline and sessiline peritrichs （Ciliophora, Oligohymenophora）based on sequences of 18S small subunit rRNA genes＂ was reported in Journal of Eukaryotic Microbiology, a key US journal in the field.
