Upon entering the human gastrointestinal tract, foodborne bacterial enteropathogens encounter, among numerous other stress conditions, nutrient competition with the host organism and the commensal microbiota. The main carbon-, nitrogen- and energy sources exploited by pathogens during proliferation in and colonization of the gut, however, have not been identified completely. During ...

The identification of interacting species and elucidation of their mode of interaction may be crucial to understand ecosystem-level processes. We analysed the activity and identity of bacterial epibionts in cultures of Daphnia galeata and of natural daphnid populations. Epibiotic bacteria incorporated considerable amounts of dissolved organic carbon (DOC), as estimated ...

Abstract Listeria monocytogenes is an emerging foodborne pathogen responsible for listeriosis. The incidence of listeriosis has increased during the last 2 decades due to the increase in consumption of ready-to-eat foods and change in food consumption habits. Outbreaks and sporadic cases of listeriosis have been reported in developed countries. These ...

Listeria monocytogenes is a foodborne opportunistic pathogen capable to switch from an environmental saprophyte to a potentially fatal human pathogen. The fact that the pathogen maintains the genes suitable for an elaborate infectious process indicates that these genes are required to survive in the environment. However, no environmental host reservoir ...

Host density can increase infection rates and reduce host fitness as increasing population density enhances the risk of becoming infected either through increased encounter rate or because host condition may decline. Conceivably, potential hosts could take high host density as a cue to up-regulate their defence systems. However, as host ...
