The incidence of non-thermophilic @entity5363 species was assessed in an unselected population-based study in a mixed urban and rural community in North Jutland, Denmark. In a 2-year study period, 11,314 faecal samples from 8302 @entity1 with @entity1902 were cultured with supplement of the filter method. We recovered a high incidence of @entity11654 (annual incidence 35/100,000 inhabitants), almost as high as the common @entity5363 /coli. In contrast, there was a very low incidence of other non-thermophilic @entity5363 species, such as @entity5363 upsaliensis. @entity11654 was, unlike @entity5363 /coli, found more frequently among small @entity1 (<1 year) and the elderly (>=  65 years). Around 10% of the @entity1 with C. consisus had @entity325 dominated by @entity2718 and @entity11621 , whereas @entity325 occurred in about 5% of @entity5363 /coli @entity1 . We observed a seasonal variation in @entity5363 /coli with a peak incidence in late summer months and autumn, whereas there was an almost constant monthly prevalence of @entity11654 . Among @entity1 participating in a questionnaire sub-study, there was a higher degree of close contacts with animals, especially @entity235 , as well as a higher travel exposure among @entity5363 /coli @entity1 compared with @entity11654 @entity1 . We did not culture any @entity11654 in stool samples from a small cohort of healthy individuals. Future studies have to focus on the clinical follow-up and the long-term risk of @entity29 in @entity11654 -positive @entity1 . We conclude that there is a high incidence of @entity11654 in Denmark.
