About Dirofilaria immitis

See Godel et al. 2012 "The genome of the heartworm, Dirofilaria immitis, reveals drug and vaccine targets" FASEB J. doi:10.1096/fj.12-205096

The heartworm Dirofilaria immitis is an important parasite of dogs. Transmitted by mosquitoes in warmer climatic zones, it is spreading across Southern Europe and the Americas at an alarming pace. There is no vaccine and chemotherapy is prone to complications. To learn more about this parasite, we have sequenced the genomes of D. immitis and its endosymbiont Wolbachia.

The D. immitis genome harbors neither DNA transposons nor active retrotransposons, and there is very little genetic variation between two sequenced isolates from Europe and the USA. Differential presence of anabolic pathways such as heme and nucleotide biosynthesis hints at the intricate metabolic interrelationship between the heartworm and Wolbachia. Comparing the proteome of D. immitis to other nematodes, and to mammalian hosts, we identify families of potential drug targets, immune modulators and vaccine candidates.

This genome sequence will support the development of new tools against dirofilariasis and aid efforts to combat related human pathogens, the causative agents of lymphatic filariasis and river blindness.

Data release and publication

The data are freely downloadable here and through the public sequence repositories. We have published a general overview of the genome of D. immitis in FASEB J based on an earlier assembly version (v1.3). Assembly version 2.2 here is much improved, and we will be publishing a synoptic overview, the transcriptome, and D. immitis' relationship to other nematodes using these data. If you would like to collaborate on that project please do contact mark.blaxter@ed.ac.uk.

We ask that you do not use the v2.2 data for global summary publications in advance of our genome manuscript publication, but are happy to assist you in directed investigations of genes and gene families of interest.

Genome Team

The D. immitis genome was sequenced by an international collaboration headed by Mark Blaxter and Pascal Mäser. Sequencing was performed by the GenePool Genomics Facility, University of Edinburgh, and FASTERIS SA, Switzerland. The version 2.2 assembly and annotation was performed by Sujai Kumar (assisted by Georgios Koutsovoulos and Alex Marshall).
