FIG. 2.

Comparative RAPD analysis of selected canine fecal and human clinical isolates. Fingerprints were generated using RAPD primer 1247 for canine and human isolates (lanes 2 to 11 and 13 to 18) and ECOR control strains (identified as to phylogenetic group) (lanes 19 to 23 and 25 to 27). Clonal groupings correspond with those shown in Table 2. Lane M, 100-bp ladder. For canine isolates 11, 12e, 19, and 30, duplicate template DNA preparations (#1 and #2 for each strain) were amplified in parallel to assess same-day, same-strain reproducibility. Sizes are indicated in base pairs.
