Identification of Prx binding partners from Streptococcus pyogenes lysates

Project description:The small prophage protein paratox (Prx) from Streptococcus pyogenes strain MGAS315 was used as bait in pull-down assays with bacterial lysates to discover potential binding partners. Bacterial lysates analyzed included MGAS315 stimulated with the quorum sensing pheromone XIP-- that induces natural competence, and MGAS315 stimulated with mitomycin C which induces bacteriophage protein expression.

Transcriptional analysis of quorum sensing deficient in Yersinia pestis CO92 at 37M-BM-0C

Project description:Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of quorum sensing was investigated by comparing transcript profiles when three quorum-sensing synthase genes are knocked out. Two strains, M-bM-^HM-^Fpgm (pigmentation-negative) mutant R88 as treatment and quorum sensing null strain R115 with mutations (M-bM-^HM-^Fpgm, M-bM-^HM-^FypeIR, M-bM-^HM-^FyspIR, and M-bM-^HM-^FluxS) as control, are used in this analysis. Six independent RNA samples from R115 cultures were paired with six independent RNA samples from R88 cultures for hybridization to six two-color microarrays. A dye-swap design was used to remove the Cy5 and Cy3 dye bias.

Yersinia pestis uses AHL-based quorum sensing to regulate metabolic functions likely to be important for flea colonization

Project description:The etiologic agent of bubonic plague, Yersinia pestis, senses cell density-dependent chemical signals to synchronize transcription between cells of the population in a process named quorum sensing. Though the closely related enteric pathogen Y. pseudotuberculosis uses quorum sensing system to regulate motility, the role of quorum sensing in Y. pestis has been unclear. In this study we performed transcriptional profiling experiments to identify Y. pestis quorum sensing regulated functions. Our analysis revealed that acyl-homoserine lactone based quorum sensing controls the expression of several metabolic functions. Maltose fermentation and the glyoxylate bypass are induced by acyl-homoserine lactone signaling. This effect was seen to be temperature conditional. Metabolism is unresponsive to quorum sensing regulation at mammalian body temperature, indicating a potential role for quorum sensing regulation of metabolism specifically during colonization of the flea vector. It is proposed that utilization of alternative carbon sources may enhance growth and/or survival during prolonged flea colonization, contributing to maintenance of plague in nature.

Identifying genetic determinants of Streptococcus pyogenes-host interactions in a murine intact skin infection model

Project description:Streptococcus pyogenes is an obligate human pathobiont associated with many disease states. Here, we present a novel model of S. pyogenes infection using intact murine epithelium. From this model, we were able to perform RNA sequencing to evaluate the genetic changes undertaken by both the bacterium and host at 5 and 24 hours post infection. Analysis of these genomic data demonstrate that S. pyogenes undergoes significant genetic adaptation to successfully infect the murine epithelium, including changes to metabolism and activation of the Rgg2/Rgg3 quorum sensing (QS) system. Subsequent experiments demonstrate that an intact Rgg2/Rgg3 QS cascade is necessary to establish a stable superficial skin infection. Furthermore, activation of this pathway results in increased murine morbidity and increased bacterial burden on the skin. This phenotype is associated with gross changes to the murine skin, as well as histopathological evidence of inflammation. Taken together, these experiments offer a novel method to investigate S. pyogenes-epithelial interactions and demonstrate that a well-studied QS pathway is critical to a persistent infection.

Transcriptional analysis of three quorum sensing signals add in experiment inYersinia pestis CO92 at 37°C

Project description:Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of quorum sensing was investigated by comparing transcript profiles when three quorum-sensing signals are added in. The strain ∆pgm (pigmentation-negative) mutant R88 was used as wild type. The three signals are AI-2, AHLs (N-(3-Oxooctanoyl)-L-homoserine lactone and N-Hexanoyl-DL-homoserine lactone).The control consisted of cells grown and treated under the same conditions without added signals.
