Description
Summary:The sit-and-wait hypothesis predicts that bacterial durability in the external environment is positively correlated with the evolution of bacterial virulence. Many bacterial pathogens have been recognized as potential sit-and-wait pathogens due to their long-term environmental survival (high durability) and high host mortality (high virulence), such as <i>Acinetobacter baumannii</i>, <i>Burkholderia pseudomallei</i>, <i>Mycobacterium tuberculosis</i>, etc. <i>Shigella flexneri</i> is a leading etiologic agent of diarrhea in China with long-term environmental survival capacity, high infection rates, and severe clinical consequences. It has multiple transmission routes like contaminated food (the food-borne route), insanitary water (the water-borne route), and direct person-to-person contacts, etc. These features make <i>Shigella flexneri</i> an ideal candidate for sit-and-wait bacterial pathogens. However, there is currently a lack of evidence to support the claim. In this study, we examine the potential of <i>S. flexneri</i> as a sit-and-wait pathogen via comparative genomic analysis, which reveals the unique features of <i>Shigella flexneri</i> in abiotic stress resistance, energy metabolism, and virulence factors and confirms that <i>S. flexneri</i> is a highly potential sit-and-wait bacterial pathogen.
