TABLE 3.

Arithmetic mean of pairwise genetic distances within C. parvum type 1, within type 2, and between type 1 and type 2^a

Comparison	All isolates		Uganda excluded
	nb	Mean distance	nb	Mean distance
Within type 1	15	0.50	7	0.43
Within type 2	65	0.61	36	0.44
Between 1 and 2	72	0.97	36	0.93

^aGenetic distances were derived from microsatellite data (Table 2) using Jaccard's index as described in Materials and Methods. 

^bNumber of pairwise comparisons.
