Note: NE = not examined.
a
Subtyped no. indicating the number of C. andersoni isolates subtyped successfully by PCR at all the four loci (MS1, MS2, MS3 and MS16); Amplified no. indicating the number of C. andersoni isolates analyzed by PCR at all the four loci (MS1, MS2, MS3 and MS16).
b
The haplotypes were arranged in accordance with the order of gene loci amplified, MS1, MS2, MS3 and MS16.
