Editing Giardia (section)

==Genome==
A ''Giardia'' isolate (WB) was the first [[diplomonad]] to have its [[genome]] sequenced. Its 11.7 million [[basepair]] genome is compact in structure and content with simplified basic cellular machineries and metabolism. Currently the genomes of several other ''Giardia'' isolates and diplomonads (the fish pathogens ''Spironucleus vortens'' and ''S. salmonicida'') are being sequenced.<ref name= Anderssonetal>{{Cite book|author= Andersson, JO| year=2010 |chapter=The Genome of Giardia and Other Diplomonads |title=Anaerobic Parasitic Protozoa: Genomics and Molecular Biology | publisher=[[Caister Academic Press]] | isbn= 978-1-904455-61-5|display-authors=etal}}</ref>

A second isolate (the B assemblage) from humans has been sequenced along with a species from a pig (the E assemblage).<ref name="Jerlström-Hultqvist2010">{{cite journal |vauthors=Jerlström-Hultqvist J, Ankarklev J, Svärd SG |title=Is human giardiasis caused by two different Giardia species? |journal=Gut Microbes |volume=1 |issue=6 |pages=379–82 |year=2010 |pmid=21468219 |pmc=3056102 |doi=10.4161/gmic.1.6.13608 |url=http://www.landesbioscience.com/journals/gmic/abstract.php?id=13608}}</ref> There are ~5000 genes in the genome. The E assemblage is more closely related to the A assemblage than is the B. A number of chromosomal rearrangements are present.
