 The distributions of Cryptosporidium spp. and G. duodenalis assemblages were determined with PCR–RFLP analysis of the SSU rRNA gene and sequence analysis of the tpi and gdh genes.
 *Sample positive for a mixed infection of C. parvum and G. duodenalis subtype B2.
 **One sample showed a mixed infection of C. parvum and G. duodenalis subtype B2, and another sample showed a mixed infection of C. bovis and G. duodenalis subtype B2.
 ***Sample positive for a mixed infection of C. parvum and G. duodenalis subtype B1.
