Lack of association between the presence of the pVir plasmid and bloody diarrhea in Campylobacter jejuni enteritis.

The main mechanisms by which Campylobacter jejuni causes diarrhea are unknown. In contrast to a recent communication, we report here the absence of an association with the plasmid pVir in patients infected with C. jejuni who developed bloody diarrhea in The Netherlands, and we suggest a role for other virulence determinants.
