FIG. 1.
Strain typing of C. jejuni isolates by PFGE. (A) Isolates from two different commercial broiler farms. Lanes 1 to 3 contained isolates from farm CF-3, and lanes 4 to 6 contained isolates from farm CF-1. Genomic DNA was digested with SmaI. (B and C) SmaI (B) and KpnI (C) typing of C. coli isolated from a broiler breeder flock and the commercial broiler progeny of this flock. Lanes 1 and 2 contained C. coli isolated from breeder parental chickens, lanes 3 and 4 contained C. coli isolated from their 6-week-old progeny, lanes 5 and 6 contained C. jejuni isolated from the progeny broilers, and lane 7 contained S. cerevisiae molecular weight markers.
