Enteropathogenic Yersinia enterocolitica are the third leading cause of bacterial diarrhoea in France 1 and Europe. 2 These bacteria have an animal reservoir and are transmitted by the faecal-oral route. The real incidence of Yersinia infections is unknown because reporting of human yersiniosis cases is not compulsory in France. Based on the number of strains sent to the French Yersinia National Reference Laboratory (YNRL), the rate of Yersinia isolation has been estimated to be 2.1/100,000. 3 This number is probably largely underestimated because the recovery of these bacteria from stools is difficult. In France and in Europe yersinioses usually occur as sporadic cases, 4 although a few outbreaks have been described. 5 and 6
Between July 1st and September 27, 2008, two clinical pathology laboratories in Creuse (central France), 83 kilometres distant, isolated 8 Y. enterocolitica strains from diarrhoeal patients. The YNRL confirmed that they were pathogenic strains. The very uncommon isolation of pathogenic Y. enterocolitica from this region suggested a possible common source of contamination. An in depth analysis of Y. enterocolitica strains isolated from this area and a temporal follow up of human yersinioses cases was performed.
