Sažetak
Microorganisms are indispensable for the function of the digestive tract, as well as tools in food technology and biotechnology. On the other hand, some of them, mostly bacteria and some fungi, as pathogens and producers of toxins are responsible for most food-borne illnesses. Now, new risks are being encountered because of the adaptation of the relevant microbial species, changing production methodologies, environment, and preferences of consumers, and, together with globalization, and the increase of global trade of foodstuffs. The consequence is the shift from traditional problems with food from mostly animal origin to fresh food of plant origin, seafood, and dry products and ingredients. Proteomic techniques offer considerable opportunities to assess production and monitoring of quality and safety of food, and proteome analysis of pathogens and infected food provides reliable information about pathogen activities during infection, outbreak of disease, and recovery period. Pathogen survival and growth on food produce is influenced by number of independent factors such as storage temperature, nature of the product, processing operations and methods, and packaging. The natural microbial flora present on produce is an additional relevant factor for pathogen survival. Proteomic, metabolomic, and transcriptomic methods are presented as effective tools for identification of cellular biomarkers for adaptive behavior of pathogenic microorganisms under different conditions such as cold and heat stress, osmotic, high hydrostatic pressure, and other stress factors. The ability of some pathogens to form biofilm is an additional survival strategy that was recently recognized. Proteomics of biofilm-forming pathogen microorganisms and identification of biomarkers typical for biofilm-grown microbial cells was given special attention in this review.
