is a Gram-negative bacterium that causes melioidosis, which can be fatal in humans. Melioidosis is prevalent in the tropical regions of Southeast Asia and Northern Australia. Ecological data have shown that this bacterium can survive as a free-living organism in environmental niches, such as soil and water, as well as a parasite living in host organisms, such as ameba, plants, fungi, and animals. This review provides an overview of the survival and adaptation of to stressful conditions induced by hostile environmental factors, such as salinity, oxidation, and iron levels. The adaptation of in host cells is also reviewed. The adaptive survival mechanisms of this pathogen mainly involve modulation of gene and protein expression, which could cause alterations in the bacteria's cell membrane, metabolism, and virulence. Understanding the adaptations of this organism to environmental factors provides important insights into the survival and pathogenesis of , which may lead to the development of novel strategies for the control, prevention, and treatment of melioidosis in the future.
是一种革兰氏阴性细菌,可引起类鼻疽病,该病在人类中可能是致命的。类鼻疽病在东南亚和澳大利亚北部的热带地区流行。生态数据表明,这种细菌可以作为一种自由生活的生物体在土壤和水等环境小生境中生存,也可以作为一种寄生虫生活在阿米巴原虫、植物、真菌和动物等宿主生物中。本综述概述了 在由盐度、氧化和铁水平等恶劣环境因素引起的应激条件下的生存和适应。还回顾了 在宿主细胞中的适应。该病原体的适应性生存机制主要涉及基因和蛋白质表达的调节,这可能导致细菌细胞膜、代谢和毒力的改变。了解该生物体对环境因素的适应为 的生存和发病机制提供了重要的见解,这可能为未来控制、预防和治疗类鼻疽病提供新的策略。
