Project description:Brucella suis infects macrophages and dendritic cells. Wild boars act as reservoirs and carriers of Brucella suis biovar 2, and there is evidence that wild boar can be the main source of infection for domestic pigs through the venereal route. Transmission through this route could be an important path for disesease dissemination. The result from this study will contribute to the overall understanding of the molecular pathogenic mechanisms involved during Brucella suis infection in European wild boar.

Transmission through this route could be an important path for disesease dissemination. The result from this study will contribute to the overall understanding of the molecular pathogenic mechanisms involved during Brucella suis infection in European wild boar. Experiment Overall Design: In this study we preliminarily characterized differential gene expression in European wild boar naturally infected with Brucella suis biovar 2 using Microarray hybridization and Real Time RT-PCR analysis. Since Brucella suis acts by infecting macrophages, we used spleen cells to analyze the gene expression response to Brucella suis infection.
Project description:Chemotherapy may cause diarrhoea, which may be associated with treatment delay and infections. The purpose of the study is to investigate whether oral supplementation with lactobacilli will alleviate chemotherapy related diarrhoea. Patients diagnosed with advanced colorectal cancer and who will receive chemotherapy will be randomly assigned to receive either lactobacilli or placebo during chemotherapy. The study is a prospective, multicenter, randomized, double-blind, placebo-controlled study. The primary outcome measure is frequency of moderate/severe diarrhoea. The study will also address safety and tolerability of chemotherapy, response to chemotherapy, and serum growth factor levels.
Project description:Lactobacillus salivarius is a member of the indigenous microbiota of the human gastrointestinal tract (GIT). Tolerance to bile stress is crucial for intestinal lactobacilli to survive in the GIT and to exert their beneficial actions. In this work, the Next-Generation Sequencing platform Illumina HiSeq 2000 was used to investigate the global response to bile in L. salivarius Ren, a potential probiotic strain isolated from a healthy centenarian. In the presence of 0.75 g liter-1 oxgall, the transcription of nearly 200 genes was detected to be associated with bile stress, including genes involved in carbohydrate and amino acid metabolism, cell envelope and fatty acid biogenesis, transcription and translation. This study improves our understanding on bile stress response in L. salivarius Ren.
Project description:Mass spectrometry analyses for determining whether 13C615N2-labeled lysines contained in the elafin (innate peptide highly expressed in lower female genital tract and down-regulated in case of HPV infection) were found in the amino acid sequence of some proteins of Lactobacilli, supporting the fundamental role of innate secretion in the growth/survival of acid lactic bacteria (L. crispatus, L. jensenii and L. iners).
