FIG. 2.

Relationships between C. jejuni isolates from retail chicken products (Chx isolates) and from humans with gastroenteritis (Hum isolates) as determined by MLST, antibiotic resistance typing, and flagellin gene short variable region typing. A phylogeny was constructed by concatenating the seven MLST loci and the hipO locus. ST and clonal complex assignment were performed using only the seven MLST loci. Ciprofloxacin sensitivity was determined by the use of the Etest. Amino acid (FlaA) and nucleotide (flaA) haplotypes (listing of variable sites) are shown for each isolate. STs for FlaA and flaA were assigned in the order of discovery. The dendrogram was constructed using the program MEGA2 (9a).
