Project description:This project presents LC-MS/MS-based proteomic datasets obtained from bacterial colonies isolated from retail chicken meat samples, as part of a study focused on the detection of Campylobacter jejuni. The isolates were initially screened using a novel chromogenic enzymatic assay targeting hippuricase activity, which is specific for C. jejuni. Selected samples, including both enzymatically positive and negative results, were subjected to in-gel digestion followed by high-resolution LC-MS/MS analysis on an Orbitrap Exploris 240 instrument.
Project description:Campylobacter jejuni has become the predominant cause of sheep abortions in the U.S. However, little is know about the genetic diversity among the isolates collected from different time periods. In this study, the genetic diversity of sheep aborion isolates of C. jejuni was investigated by Array-based CGH

Project description:Campylobacter spp. cause food-borne illnesses worldwide due to contaminated food and cross-contamination. This is at least partly the result of Campylobacter resistance in the food production chain, as modern food production facilitates the emergence and spread of resistance through intensive use of antimicrobials and international trade in raw materials and food products. The biofilm 'lifestyle' of Campylobacter contributes to this spread as it enables them to withstand stress in the environment both outside and inside the host. Campylobacter adhesion and biofilm formation has major implications for the food industry, where biofilms can be persistent sources of contamination. Lavender essential oil, ethanol extracts, and its main compounds (linalool, linalyl acetate) reduce the AI-2 biosensor response in Vibrio harveyi without lowering AI-2 levels or affecting the luxS gene in Campylobacter jejuni. This suggests lavender compounds may block AI-2 detection—likely by interfering with its receptor—offering a natural strategy to disrupt bacterial communication, biofilm formation, and virulence.
