Through recent advances in our understanding of microbial:plant interactions it is becoming apparent that human pathogens, principally, Escherichia coli O157:H7 and Salmonella are adapted to survive in the plant environment. The aforementioned pathogens have surface epitopes that can bind to plant structures such as stomata to aid attachment. In addition, Salmonella is attracted and able to metabolize nutrients contained within the apoplastic fluid of plants. The question of internalization into the inner tissue of plants remains inconclusive largely because of the problems encountered in detecting low pathogen levels. Nevertheless, once internalized human pathogens can trigger and potentially evade plant defenses that are typically induced by phytopathogens. Although more research in this area is required, the hypothesis that human pathogens have adapted to the plant environment as part of their natural lifecycle appears to be supported.
通过我们对微生物与植物相互作用的理解的最新进展，很明显，人类病原体，主要是大肠杆菌 O157:H7 和沙门氏菌，已经适应了在植物环境中生存。上述病原体具有可以与植物结构（如气孔）结合的表面表位，以帮助附着。此外，沙门氏菌被吸引并能够代谢植物质外体液体中所含的营养物质。病原体进入植物内部组织的问题仍然没有定论，主要是因为在检测低水平病原体时遇到了问题。然而，一旦进入植物内部，人类病原体就可以触发并可能逃避植物防御，这些防御通常是由植物病原体引起的。尽管该领域需要更多的研究，但人类病原体已经适应植物环境作为其自然生命周期的一部分的假设似乎得到了支持。
