The rDNA repeat unit from a new human Giardia duodenalis strain shows significant differences from the previously reported G. duodenalis rDNA repeat. Twelve base‐pair changes occurred in 490 bp of the SSrRNA gene and new restriction enzyme sites occurred in the LSrRNA gene. The overall length of the rRNA genes is the same but the spacer is 76 bp longer than previously reported. A boundary within the spacers of the two different rDNA units divides a region of 50% homology near the LSrRNA gene from a region of 80% homology toward the SSrRNA gene. This boundary region includes two copies of a 78 bp repeat.
