Abstract:
... Currently, it is clear that the luxS gene has an impact on the process of biofilm formation in Campylobacter jejuni. However, even within the species, naturally occurring strains of Campylobacter lacking the luxS gene exist, which can form biofilms. In order to better understand the genetic determinants and the role of quorum sensing through the LuxS/AI-2 pathway in biofilm formation, a set of mut ...

Abstract:
... Campylobacter and Salmonella are responsible for the two major foodborne zoonotic diseases in Europe; poultry is the main infection source. Campylobacter cannot grow under aerobic conditions, but can show aerobic survival when co-cultured with other microorganisms; however, its interaction with Salmonella has not been studied yet. In this study, these two bacteria were co-cultured under controlled ...

Abstract:
... Campylobacter jejuni is a globally important foodborne pathogen that can exist environmentally in a viable but non-culturable (VBNC) state, leading to missed detection of VBNC cells in food and false results in epidemiological surveillance. To establish a method for its resuscitation from the VBNC state and enable better detection, the mechanisms by which C. jejuni are induced into the VBNC state ...

Abstract:
... Campylobacter coli and C. jejuni, the causing agents of campylobacteriosis, are described to be undergoing introgression events, i.e., the transference of genetic material between different species, with some isolates sharing almost a quarter of its genome. The participation of phages in introgression events and consequent impact on host ecology and evolution remain elusive. Three distinct prophag ...

Abstract:
... Cognition is likely to have fundamental effects on the behaviour and fitness of animals, but measuring cognitive abilities can be a challenge because performance on cognitive tests can be influenced by ‘noncognitive’ factors. Parasitic infections, for example, could lead to temporary changes in the ability or motivation of an individual to participate in cognitive tasks, thereby altering cognitive ...
