Abstract

Species with a chitinous exoskeleton are overrepresented among the aquatic organisms carrying Mycobacterium ulcerans (MU) in nature and laboratory experiments have demonstrated the enhancing effects of chitin on the growth of MU. Field surveys identified pH as one of the key parameters delineating the distribution of MU in tropical regions. The present study investigated the relationship between chitin and pH in MU growth. By focusing on pH variations in the field, our results revealed that chitin enhanced MU growth in acidic environments. The present study provides new information on the ecological conditions favoring the development of this mycobacterium in nature.

摘要

在自然界中携带溃疡分枝杆菌（MU）的水生生物中，具有几丁质外骨骼的物种占比过高，并且实验室实验已经证明几丁质对MU生长具有促进作用。实地调查确定pH值是界定热带地区MU分布的关键参数之一。本研究调查了几丁质与pH值在MU生长中的关系。通过关注实地的pH值变化，我们的结果显示几丁质在酸性环境中促进了MU的生长。本研究提供了关于有利于这种分枝杆菌在自然界中生长的生态条件的新信息。
