Biofilm Formation and Virulence of Shigella flexneri is Modulated by pH

Project description:In this study, we probed factors that could influence Shigella pathogenesis. We show that in basic pH conditions, deoxycholate-induced biofilm formation and virulence of Shigella are attenuated. We utilized RNA-sequencing to investigate pathways enriched in bacterial cells in biofilms.

The expression profiles analysis of a virulence plasmid-cured strain of shigella flexneri

Project description:In this study, we analyzed the expression profiles of a virulence plasmid-cured strain and wild-type strain of shigella flexneri. The results showed that the genes of glp regulon were upregulated in mutant bacteria in stationary phase cultures. The two strains were cultured in LB broth into log-phase and stationary phase respectively. Then, the total RNAs were extracted and analyzed by Nimblegen biochips.

Biofilm Formation and Virulence of Shigella flexneri Are Modulated by pH of Gastrointestinal Tract.

Project description:Shigella infection remains a public health problem in much of the world. Classic models of Shigella pathogenesis suggest that microfold epithelial cells in the small intestine are the preferred initial site of invasion. However, recent evidence supports an alternative model in which Shigella primarily infects a much wider range of epithelial cells that reside primarily in the colon. Here, we investigated whether the luminal pH difference between the small intestine and the colon could provide evidence in support of either model of Shigella flexneri pathogenesis. Because virulence factors culminating in cellular invasion are linked to biofilms in S. flexneri, we examined the effect of pH on the ability of S. flexneri to form and maintain adherent biofilms induced by deoxycholate. We showed that a basic pH (as expected in the small intestine) inhibited formation of biofilms and dispersed preassembled mature biofilms, while an acidic pH (similar to the colonic environment) did not permit either of these effects. To further elucidate this phenomenon at the molecular level, we probed the transcriptomes of biofilms and S. flexneri grown under different pH conditions. We identified specific amino acid (cysteine and arginine) metabolic pathways that were enriched in the bacteria that formed the biofilms but decreased when the pH increased. We then utilized a type III secretion system reporter strain to show that increasing pH reduced deoxycholate-induced virulence of S. flexneri in a dose-dependent manner. Taken together, these experiments support a model in which Shigella infection is favored in the colon because of the local pH differences in these organs.

Role of PhoPQ TCS plays in Shigella virulence

Project description:To explore what important role of PhoPQ TCS plays in Shigella virulence, the Agilent microarray technologies was used to compare the transcriptional profiles of Shigella flexneri 2a 301 and △phoPQ mutant strains at middle-log phase (6 h) or early-stationary phase (10 h) under LB growth conditions.

Transcriptional Profile of the Shigella flexneri Response to Berberine

Project description:Berberine is a natural isoquinoline alkaloid found in Chinese medicinal herbs which is active against a variety of microbial infections. To examine the potential effects of berberine on Shigella flexneri, a whole-genome DNA microarray was constructed and transcriptome analysis of the cellular responses of S.flexneri when exposed to Berberine Chloride (BC) was performed.
