| genotyping of giardia lamblia isolates from humans in china and korea using ribosomal dna sequences. | genetic characterization of a total of 15 giardia lamblia isolates, 8 from anhui province, china (all from purified cysts) and 7 from seoul, korea (2 from axenic cultures and 5 from purified cysts), was performed by polymerase chain reaction amplification and sequencing of a 295-bp region near the 5' end of the small subunit ribosomal dna (eukaryotic 16s rdna). phylogenetic analyses were subsequently conducted using sequence data obtained in this study, as well as sequences published from other ... | 2000 | 10958483 |
