Project description:We have isolated and characterized several bacteriophages infecting Pseudomonas aeruginosa distantly related to Felix O1 virus and proposed they form a new subfamily named Felixounavirinae. The infectious cycle of bacteriophages belonging to this subfamily has not been studied yet in terms of gene expression. The present study reports the RNA-Seq analysis of bacteriophage PAK_P3 infecting PAK strain of P. aeruginosa. RNA profile of Host and Phage at 0min, 3.5min and 13 min after infection of Pseudomonas aeruginosa PAK strain with the Pseudomonas phage PAK P3. Three biological replicates for each time point.

Project description:Intrinsic and acquired defenses against bacteriophages, including Restriction/Modification, CRISPR/Cas, and Toxin/Anti-toxin systems have been intensely studied, with profound scientific impacts. However, adaptive defenses against phage infection analogous to adaptive resistance to antimicrobials have yet to be described. To identify such mechanisms, we applied an RNAseq-based, comparative transcriptomics approach in different \textit{Pseudomonas aeruginosa} strains after independent infection by a set of divergent virulent bacteriophages. A common host-mediated adaptive stress response to phages was identified that includes the Pseudomonas Quinolone Signal, through which infected cells inform their neighbors of infection, and what may be a resistance mechanism that functions by reducing infection vigor. With host transcriptional machinery left intact, we also observe phage-mediated differential expression caused by phage-specific stresses and molecular mechanisms. These responses suggest the presence of a conserved Bacterial Adaptive Phage Response mechanism as a novel type of host defense mechanism, and which may explain transient forms of phage persistence.

Project description:The ability of bacteriophages to kill bacteria is well known, as is their potential use as alternatives to antibiotics. As such, bacteriophages reach high doses locally through infection of their bacterial host in the human body. In this study we assessed the gene expression profile, by means of whole transcriptome analysis, of peripheral blood mononuclear cells (PBMCs) derived from a healthy human donor and stimulated with a Pseudomonas aeruginosa phage PNM lysate, or P. aeruginosa strain 573. The PBMCs were stimulated for 20 h, followed by lysis of the cells and RNA extraction. In total, three stimulations were performed: control sample (i.e. not stimulated), P. aeruginosa phage PNM lysate and P. aeruginosa strain 573. Each stimulation was conducted in triplicate. The transcriptome analysis showed that the phage induce a clear immunological responses. Both pro- and anti-inflammatory genes were up-regulated in the PBMCs in the presence of the phage or its bacterial host. Our results indicate that bacteriophages might play a bigger role in the immune response then previously described and might have a broader effect than the clearing of bacterial infections alone, such as the suppression of the immune response to benefit their own survival.
