Frequencies of different observed patterns of appearance and re-appearance of parasite genotypes.

The frequencies of the patterns are summed over all hosts and genotypes. + indicates detection of the genotype by CE; - indicates that it was not detected at that survey. Each of the 63 possible patterns occurred at least 3 times.所有宿主及基因型对应的模式频率均已完成求和汇总。符号"+"代表通过毛细管电泳（CE）检测到该基因型，符号"-"代表在该次调查中未检测到该基因型。全部63种可能的模式均至少出现3次。
