Psoroptes mites are responsible for causing psoroptic mange in various animals, leading to economic losses among farmers of cattle, sheep and goats.[1] It is also known as sheep scab and cattle scab.[1] The disease is highly infectious, and is transmitted via fenceposts and other structures that livestock use when scratching themselves.[1] The mites have mouthparts which do not pierce the skin, but are adapted to feeding on the surface, where the mites abrade the stratum corneum.[1] See Mites of livestock for photographs of infestations by Psoroptes.

Taxonomy

[edit | edit source]

Psoroptes has been traditionally considered to include five species living on different host species, but genetic analysis has reduced the genus to a single species, Psoroptes ovis.[2]
