FIG. 1.

Chromosomal locations of three C. parvum RFLP markers. Oocyst DNA (a, c, and e) was fractionated by CHEF electrophoresis (COWP and TRAP-C1) or PFGE [poly(T)] in parallel with S. cerevisiae DNA standards (a and c, left lanes; e, right lane) and Hansenula wingei chromosomes (e, middle lane). The locations of C. parvum chromosomal bands are indicated with horizontal lines. The molecular sizes of these bands are 1.54, 1.44, 1.24, 1.08, and 1.03 Mb from top to bottom, respectively (2). Panels b, d, and f show the results of Southern analyses with the corresponding probes.
