FIG. 3.

Restriction polymorphism in the E. bieneusi ITS region. PCR products amplified from the ribosomal ITS of three human and one pig-propagated isolate were restricted with MspA1I. Notice the shared genotype between the human sample ER and the pig sample 320/97P (see Table 1). The remaining human samples BF and WP share a different genotype at this locus. BF⁻, undigested PCR product; M, 100-bp ladder. The position of the 600-bp band is shown on the left.
