FIG. 1.

Distribution of short sequence repeat fingerprints of M. avium subsp. paratuberculosis isolates from Ohio. Open diamonds indicate the counties from which samples were obtained. Closed circles indicate the counties from which a sample was found to be M. avium subsp. paratuberculosis positive. The alleles are indicated by the number of G repeats followed by the number of GGT repeats. When samples were obtained from more than one farm in a county, they are indicated as F1, F2, and so on. The number of isolates from a particular farm is one unless otherwise indicated by a number in parentheses.
