铜绿假单胞菌是一种无处不在的机会性病原体,在它所占据的不同生态位中形成健壮的生物膜。当这种生物从土壤或水生环境转变为与宿主相关的生活方式时,需要许多生理适应。虽然这些生态位之间的许多条件不同,但温度变化是在这种转变过程中导致生理压力的一个因素。为了了解温度如何影响这种病原体的生物膜形成,我们使用蛋白质组学和转录组学工具来阐明环境相关和宿主相关温度下的生理反应。这些研究揭示了铜绿假单胞菌中各种蛋白质的差异表达,包括与EPS基质相关的噬菌体蛋白。这种丝状噬菌体在宿主温度下被诱导,并需要在人体温度下形成完全的生物膜。这些数据强调了温度变化在生物膜形成中的重要性,并提示噬菌体蛋白可能是生物膜相关感染的可能治疗靶点。
Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen that forms robust biofilms in the different niches it occupies. Numerous physiological adaptations are required as this organism shifts from soil or aquatic environments to a host-associated lifestyle. While many conditions differ between these niches, temperature shifts are a factor that can contribute to physiological stress during this transition. To understand how temperature impacts biofilm formation in this pathogen, we used proteomic and transcriptomic tools to elucidate physiological responses in environment-relevant vs. host-relevant temperatures. These studies uncovered differential expression of various proteins including a phage protein that is associated with the EPS matrix in P. aeruginosa. This filamentous phage was induced at host temperatures and was required for full biofilm-forming capacity specifically at human body temperature. These data highlight the importance of temperature shift in biofilm formation and suggest bacteriophage proteins could be a possible therapeutic target in biofilm-associated infections.
