Multilocus sequence typing for investigation of diversity of Campylobacter jejuni strains from humans and environment in Norway.

This report describes the use of the Multilocus Sequence Typing (MLST) method for typing 32 strains previously identified as Campylobacter jejuni. This system identified a great diversity between the investigated strains. The majority of strains belonged to already existing alleles found on the Campylobacter MLST home page, and most of them represented clonal complexes ST-21 and ST-45, but there were some newly identified alleles as well.
