Transcriptome profiling of Listeria monocytogenes during growth on a RTE-meat matrix

Project description:The gene expression profiles of L. monocytogenes strain F2365 grown in BHI agar (reference) or on a turkey deli meat (query) was examined. Aminosilane-coated cDNA microarray slide was used. The data from the normalized ratio of query to reference signal for each spot were transformed using a log2 scale. The expression level of genes obtained from the mean of each gene on the twelve slides was considered significantly different over 1.5 fold changes. Thirty nine and forty five genes in L. monocytogenes grown on a turkey meat matrix were upregulated and downregulated, respectively. To examine the gene expression profiles of L. monocytogenes grown in BHI agar or on a turkey deli meat, L. monocytogenes strains 4b F2365 aminosilane-coated cDNA microarray slide was used. Cy3 and Cy5 dyes were used for cDNA labelling. Data were obtained from three biological and four technical replicates (n = 12). Each biological replicate included a flip dye assay. TM4 package developed by TIGR was used to analyze the data.

Transcriptomic analysis of biofilm formation in persistent and transient Listeria monocytogenes from the retail deli environment

Project description:Persistence of Listeria monocytogenes in retail deli environments is a serious food safety issue, potentially leading to cross-contamination of ready-to-eat foods such as deli meats, salads, and cheeses. We previously discovered strong evidence of L. monocytogenes persistence in delis across multiple states. We hypothesized that this was correlated with isolates’ innate characteristics, such as biofilm-forming capacity or gene differences.We further chose four isolates for RNA-sequencing analysis and compared their global biofilm transcriptome to their global planktonic transcriptome. Analysis of biofilm vs planktonic gene expression did not show the expected differences in gene expression patterns. Overall, L. monocytogenes persistence in the deli environment is likely a matter of poor sanitation and/or facility design, rather than isolates’ biofilm-forming capacity, sanitizer tolerance, or genomic content

Immunoproteome profiling of Listeria monocytogenes under mild acid and salt stress conditions

Project description:Listeria monocytogenes is the ubiquitous food-borne pathogen which causes listeriosis, a disease with a high mortality rate, mostly transmitted through contaminated ready-to-eat foods (EFSA, 2018). To better understand the systemic response of such microorganism exposed at three environmental factors (T, pH and NaCl), the proteome of a L. monocytogenes strain, which was isolated from a meat product (Coppa di testa) linked to a listeriosis outbreak occurred in Marche region (Italy) in 2016, was investigated in order to identify differences in its protein patterns.

Listeria monocytogenes Grown at Refrigeration Temperature Shows Reduced Acid Survival and an Altered Transcriptional Response to Acid Shock

Project description:Survival of the foodborne pathogen Listeria monocytogenes in acidic environments (e.g., stomach and low pH foods) is vital to its transmission. L. monocytogenes grows at temperatures as low as 2°C, and refrigerated, ready-to-eat foods have been sources of L. monocytogenes outbreaks. The purpose of this study was to determine whether growth at a low temperature (i.e., 7°C) affects the response of L. monocytogenes to sudden acid shock.

The metagenomic data of ready-to-eat foods and human fecal samples

Project description:There are 18 ready-to-eat food samples (8 ready-to-eat meat, 7 ready-to-eat vegetables and 3 ready-to-eat fruit) and 6 human faecal samples. The samples were sequenced on the Illumina, NovaSeq PE150.

Untargeted and targeted transcriptome analysis to decipher the impact of exogenous fatty acids in cold stress adaptation of Listeria monocytogenes

Project description:Listeria monocytogenes is a ubiquitous and psychrophilic foodborne pathogen commonly found in raw materials, ready to eat products and food environments. It was previously demonstrated that L. monocytogenes can grow faster at low temperature when unsaturated fatty acids (UFA) are present in its environment. In this study, we used comparative gene expression profiling of RNA-sequencing data to understand the impact of UFA on the behavior and cold adaptation of L. monocytogenes. We demonstrate that the incorporation of UFA into the membrane induces changes in the regulation of overall fatty acid biosynthesis, which prompts us to propose two hypotheses for UFA synthesis in L. monocytogenes. The general stress response is also highly impacted by the incorporation of UFA into the membrane at low temperature. In particular, we hypothesize that transcriptional regulation of cspB is not a temperature dependent mechanism, but could be related to a membrane fluidity stimulus. Furthermore, when UFA are incorporated into the membrane at low temperature, we observed overexpression of genes involved in flagella assembly. This study sheds light on the cold adaptation of L. monocytogenes in the presence of exogenous FA and on potential concerns for controlling these bacteria in food environments.
