Abstract
Two types of endosymbiotic bacteria were identified in the gastrodermis of the marine invertebrate Xenoturbella bocki (Xenoturbellida, Bilateria). While previously described Chlamydia-like endosymbionts were rare, Gammaproteobacteria distantly related to other endosymbionts and pathogens were abundant. The endosymbionts should be considered when interpreting the poorly understood ecology and evolution of Xenoturbella.
摘要
在海洋无脊椎动物 Xenoturbella bocki（Xenoturbellida，两侧对称动物）的胃皮中鉴定出两种内共生细菌。虽然以前描述的类衣原体内共生体很少见，但与其他内共生体和病原体关系较远的γ变形菌却很丰富。在解释 Xenoturbella 理解甚少的生态和进化时，应该考虑到这些内共生体。
