越来越多的研究表明某些在环境中普遍存在的人与动物的病原微生物能够跨界侵染不同生物界的寄主。本文就Serratia marcescens,Enterobacter cloacae,Pseudomonas aeuriginosa,Klebsiella pneumoniae等动物条件病原细菌环境菌株跨界侵染植物的研究现状进行了综述。这些病原菌在自然界中普遍存在,能够利用与感染人类相同或不同的侵染策略跨界侵染植物,以拓宽其寄主范围。其中,肺炎克雷伯氏菌(Klebsiella pneumoniae)能在自然条件下引起玉米发生顶腐病,揭示了环境中的某些植物可作为各种病原细菌的天然储存库,在条件合适的情况下可能会感染人类和动物,以及在食品生产中的潜在危害。对这些跨界病原菌的研究,在人、动物和植物流行病学上具有非常重要意义,也为环境科学提出了新的研究热点。
A growing body of research shows that some human and animal pathogenic microorganisms that are prevalent in the environment can cross-contaminate hosts in different biological kingdoms. In this paper, the status of research on transboundary infestations of environmental strains of pathogenic bacteria such as Serratia marcescens, Enterobacter cloacae, Pseudomonas aeuriginosa and Klebsiella pneumoniae were reviewed. These pathogens are ubiquitous in nature and are capable of transplanting plants across the border using the same or different infection strategies as in humans to broaden their host range. Among them, Klebsiella pneumoniae can cause top rot in maize under natural conditions, revealing that some plants in the environment can be used as natural repositories for various pathogenic bacteria, and under conditions suitable, Can infect humans and animals, and the potential hazards in food production. The research on these transboundary pathogens is of great importance in human, animal and plant epidemiology, and also puts forward new research hotspots for environmental science.
