Constitutive aneuploidy and genomic instability in the single-celled eukaryote Giardia intestinalis.

Abstract excerpt

Giardia intestinalis is an important single-celled human pathogen. Interestingly, this organism has two equal-sized transcriptionally active nuclei, each considered diploid. By evaluating condensed chromosome numbers and visualizing homologous chromosomes by fluorescent in situ hybridization, we determined that the Giardia cells are constitutively aneuploid. We observed karyotype inter-and intra-population...
