Fourteen Giardia duodenalis isolates were examined using the RAPD (random amplified polymorphic deoxyribonucleic acid) technique. Simple reproducible polymorphisms were generated using 3 different RAPD primers. The results generated by each primer were very similar and were significantly correlated with each other. These data were then compared to existing isoenzyme electrophoresis data on the same isolates. The RAPD data divided the isolates into 10 groupings or rapdemes while the isoenzyme data divided them into 10 similar zymodemes. Both methods grouped 4 isolates (BAH42, BAH44c9, BAH12c9 and BAH39c7), which comprised a phenotypically heterogeneous assemblage with respect to growth rate and metabolism, into similar groupings. The 2 methods were significantly correlated (P<0.001). It will therefore be possible to use RAPD for the characterization of isolates of Giardia, and other parasites such as Cryprosporidium, which are refractory to cultivation in vitro.
