Mycobacterium ulcerans is the causative agent of Buruli ulcer - a necrotizing skin infection. As an environmental pathogen, it has developed stress response mechanisms for survival. Similar to endospore formation in M. marinum, it is likely that M. ulcerans employs sporulation mechanisms for its survival and transmission. In this review, we modeled possible transmission routes and patterns of M. ulcerans from the environment to its host. We provided insights into the evolution of M. ulcerans and its genomic profiles. We discuss reservoirs of M. ulcerans as an environmental pathogen and its environmental survival. We comprehensively discuss sporulation as a possible stress response mechanism and modelled endospore formation in M. ulcerans. At last, we highlighted sporulation associated markers, which upon expression trigger endospore formation.
Keywords: Buruli ulcer; Mycobacteria ulcerans; environmental pathogen; mycobacteria; sporulation; stress response mechanisms.
Buruli ulcer is an infectious disease characterized by extensive sores on the skin and soft body tissues. The disease is caused by a bacterium called Mycobacterium ulcerans and is mainly found in tropical countries. Over the years, several attempts to understand the means by which humans get into contact with this bug as well as how it thrives in its host remain futile. In this review, we describe a possible survival strategy, known as sporulation, that is adopted by the pathogen for dispersal and survival.
