Campylobacter jejuni, a foodborne pathogen

Campylobacter jejuni

Since 2005, Campylobacterhas been the leading cause of enteritis in humans worldwide. Although largely underestimated, the number of confirmed cases of Campylobacteriosis was 246,158 in 2017 with an EU notification rate of 64.8 per 100,000 population. Infection with C. jejuni can lead to chronic sequelae, such as Guillain-Barré syndrome (GBS), characterized by damage to the peripheral nervous system leading to reversible neuromuscular palsy. The main reservoirs of C. jejuni are avian and poultry species. In food, the occurrence of Campylobacter remains high in broiler meat and it is considered to be the single most important source of human campylobacteriosis. In 2017, 37.4% of 13,445 samples of fresh chicken meat were found to be Campylobacter positive. C. jejuni is Secalim's model pathogen studied in the framework of thermatic 1: understand the bacterial behaviour and thematic 2: assess the safety risk. The ongoing projects on this topic are the CHILLING and ESCAPE projects.

PhD theses supervised on this topic:

Campylobacter jejuni has been one of the bacterial models studied at Secalim for many years. Studies of Secalim on C. jejuni concern the influence of stress on the pathogen's behaviour, and especially the oxydative stress. Several PhD theses have been devoted to it (2020, 2016, 2015a, b,2012,2010a,b et c et 2007) and several projects as well, as can be seen from this list of publications.
