text: Single cells of uncultured bacteria, archaea and protists, as well as individual viral particles and single fungal spores have been sequenced with the help of MDA.
  The ability to sequence individual cells is also useful in combating human disease.  Genomes from single human embryonic cells have been successfully amplified for sequencing using MDA, allowing preimplantation genetic diagnosis (PGD): screening for genetic health issues in an early-stage embryo before implantation.  Diseases with heterogeneous properties, such as cancer, also benefit from MDA-based genome sequencing's ability to study mutations in individual cells.
  The MDA products from a single cell have also been successfully used in array-comparative genomic hybridization experiments, which usually require a relatively large amount of amplified DNA.
