Multilocus genotyping by PCR/sequencing of beta-giardin (bg), triose phosphate isomerase (tpi), and glutamate dehydrogenase (gdh) genes of representative number of positive samples (65) revealed that assemblages A, B and mixed infections (A + B) occurred in 26/65 (40.0%), 32/65 (49.2%) and 10.8% (7/65) of the analyzed isolates, respectively.
From the results, we concluded that the highly polymorphic gene loci such as GDH gene locus might provide us an opportunity to obtain a detailed molecular data even from the samples with multiple-subgenotype mixed infections.
