Transcriptomic profiling of antibiotic-resistant Salmonella Heidelberg in the presence of commensal Escherichia coli of poultry origin

Project description:The non-typhoidal Salmonella enterica serotype Heidelberg is a major foodborne pathogen primarily transmitted to humans through contaminated poultry products. Current control measures emphasize novel approaches to mitigate Salmonella Heidelberg colonization in poultry and the contamination of poultry products, thereby reducing its transmission to humans. This study highlight that commensal E. coli 47-1826 can potentially be used to control of S. Heidelberg 18-9079 in poultry

Translation landscape of the enteric pathogen Salmonella enterica serova Typhimurium

Project description:Many non-typhoidal serovars of Salmonella such as Salmonella enterica serovar Typhimurium (S. Typhimurium) are the leading cause of food-borne gastroenteritis, resulting in millions of infections each year and sometimes death. Salmonella enterica serovar Typhimurium is the most common non-typhoidal Salmonella strain isolated from patients around the world and is used as a mouse model to study bacterial pathogenesis and host-microbe interactions. Furthermore, S. Typhimurium is an important pathogen in livestock animals including chickens and cattle. S. Typhimurium utilises a multitude of virulence factors to reach and invade host cells and for its intracellular survival. However, little is known about the mechanism of protein synthesis of these virulence factors at the codon level. Here, we performed RNA-seq and ribosome profiling. Ribosome profiling allows the global mapping of translating ribosomes on the transcriptome and therefore provides direct measure of protein synthesis.

Comparative analysis of Salmonella Typhi, Paratyphi A, Enteritidis and Typhimurium core proteomes

Project description:Salmonella enterica subsp. enterica contains more than 2,600 serovars of which four are of major medical relevance for humans. While the typhoidal serovars (Typhi and Paratyphi A) are human-restricted and cause enteric fever, non-typhoidal Salmonella serovars (Typhimurium and Enteritidis) have a broad host range and predominantly cause gastroenteritis. In this study, we compared the core proteomes of Salmonella Typhi, Paratyphi A, Typhimurium and Enteritidis using contemporary proteomics. Five isolates, covering different geographical origins, and one reference strain per serovar were grown in vitro to the exponential phase. Protein levels of orthologous proteins between serovars were compared and subjected to gene ontology term enrichment and inferred regulatory interactions. Differential expression of the core proteomes of the typhoidal serovars appears mainly related to cell surface components and, for the non-typhoidal serovars, to pathogenicity. Our findings may guide future development of novel diagnostics and vaccines, and understanding of disease progression.

Influence of Microbial and Host Cell Sublethal Heat Stress on S. Typhimurium Gene Expression

Project description:Environmental stress contributes to the outcome of infection by impacting both microbial virulence and host susceptibility to infection. Thermal processing, commonly used for decontamination of poultry in the food industry, may elicit sublethal stress on resistant serovars of Salmonella. We employed traditional heat shock temperatures (42 and 48ºC), similar to avian body temperature and poultry processing conditions, to study gene expression of Salmonella enterica serovar Typhimurium. Microarray analysis indicated that thermal shock at 42°C and 48°C induced expression of SPI-2 and SPI-5 genes, whose products are required for adhesion and survival. However, SPI-1 genes, responsible for invasion of Salmonella into host cells, were down-regulated following exposure to 42°C and 48°C. Bacterial adhesion assays showed greater adhesion of heat-stressed S. Typhimurium to Caco-2 cells compared to non-stressed bacteria. In addition, subjecting Caco-2 cells to mild heat shock (39°C), which is similar to human fever, enhanced host cell susceptibility to bacterial adhesion. Data indicate that thermal stress enhances bacterial colonization and host cell susceptibility to adhesion during S. Typhimurium infection.

Typhoidal Salmonella Dendritic Cell Survival Mechanism Revealed by Dual RNA sequencing

Project description:Salmonella enterica represent a major disease burden worldwide. While non-typhoidal Salmonella (NTS) serovars trigger self-limiting diarrhoea, leading to occasional secondary bacteraemia, S. enterica serovar Typhi is responsible for potentially life-threatening Typhoid fever. Dendritic cells (DCs) are key professional antigen presenting cells of the human immune system. The ability of pathogenic bacteria to subvert DC functions and prevent T cell recognition contributes to their survival and dissemination within the host. Here, we adapted Dual RNA-sequencing to define how different Salmonella pathovariants remodel their gene expression in tandem with that of infected DCs. We find DCs harness iron handling pathways to defend against invading Salmonellas, which, the human pathogen S. Typhi is able to circumvent. We show that S. Typhi mounts a robust response to host oxidative stress to avoid host iron-mediated defence mechanisms. In parallel, we provide evidence that invasive non-typhoidal Salmonella employs several strategies to impair DC functions and undertake alternative nutrient scavenging strategies to survive in the hostile intracellular environment.
