Restriction-fragment-length polymorphism analysis of small-subunit rRNA genes of Blastocystis hominis isolates from geographically diverse human hosts

Parasitol Res. 2000 Jan;86(1):57-61. doi: 10.1007/s004360050010.

Abstract

Genomic diversity among 14 isolates of Blastocystis hominis from 4 different geographic locations was examined by small-subunit rRNA (ssu rRNA) restriction-fragment-length polymorphisms (RFLP) using 5 different restriction endonucleases. On the basis of the observed RFLP patterns among the isolates, a total of 12 genotypes were identified, with 7 isolates exhibiting mixed RFLP genotypes. There was no correlation between B. hominis geographic origin and RFLP banding pattern or genotype.
