The campylobacteriosis (with clinical symptoms like diarrhea, abdominal cramps, and fever) is mostly self-limiting but sequelae like Guillian–Barré syndrome and reactive arthritis have been described ( Poropatich et al., 2010). lari suggest that stress response mechanisms described for one Campylobacter species might be not necessarily transferable to other Campylobacter species.Ĭampylobacter is one of the most common causative agents of bacterial food-borne gastroenteritis in humans worldwide. However, the pronounced differences in the expression pattern between C. The transcriptomic profiles showed enhanced gene expression of several chaperones like dnaK, groES, groEL, and clpB in both strains, indicating a general involvement in the heat stress response within the Campylobacter species. lari RM2100 were differentially expressed. None of the strains survived at 46☌ for more than 8 h and approximately 20% of the genes of C.
In this study, the stress response of Campylobacter coli and Campylobacter lari to elevated temperatures (46☌) was investigated by survival assays and whole transcriptome analysis. Although some aspects of the heat stress response in Campylobacter jejuni are already known, information about the stress response in other Campylobacter species are still scarce. Nevertheless, Campylobacter is able to survive in the environment and food products. This might be due to the lack of many stress response mechanisms described in other bacteria. are one of the most important food-borne pathogens, which are quite susceptible to environmental or technological stressors compared to other zoonotic bacteria.
