About Sarcoptes scabiei


Sarcoptes scabiei, the itch mite, is a parasitic arthropod that burrows into skin and causes scabies. The mite is cosmopolitan, meaning it can be found in all parts of the world. Humans are not the only mammals that can become infected. Other mammals, such as wild and domesticated dogs and cats as well as ungulates, wild boars, bovids, wombats, koalas, and great apes are affected. The discovery of the itch mite in 1687 marked scabies as the first disease of humans with a known cause. The Italian biologist Diacinto Cestoni showed in the 18th century that scabies is caused by the mite Sarcoptes scabiei, variety hominis. The disease produces intense, itchy skin rashes when the impregnated female tunnels into the stratum corneum of the skin and deposits eggs in the burrow. The larvae, which hatch in three to 10 days, move about on the skin, moult into a nymphal stage, and then mature into adult mites. The adult mites live three to four weeks in the host's skin.

The assembly presented is the SarSca1.0 assembly submitted to INSDC with the assembly accession GCA_000828355.1. The genome is that of Sarcoptes scabiei var. canis.


Ensembl Metazoa displays the SscaA1.2 (August 2017) gene set from VectorBase. Genes were annotated with MAKER, combining EST data with de novo prediction methods [1]; non-coding RNA genes were added with the Ensembl Genomes pipeline.
