Sarcoptes-ELISA Dog

Enzyme immunoassay for the detection of IgG antibodies to the pathogen of sarcoptic mange, Sarcoptes scabiei var. canis

In most cases, sarcoptic infections occur subclinically and last chronically with sarcoptic mites. Therefore, they can hardly be detected with conventional diagnostic methods (direct detection of the scabies mites).

A pathognomonic symptom for sarcoptic mange is pruritus, which is also occurring in a number of other skin diseases in dogs. For this reason the test is very well-suited for the differential diagnosis of other skin diseases.

Sarcoptic mites cause an immune response, depending on the infective dose and the immune status of the host animal. An increase of specific humoral antibodies (IgG) is detectable in experimentally infected dogs, at the earliest after three weeks.

The sensitivity and specificity of this test, which was evaluated in 113 dogs with or without clinically confirmed sarcoptic mange, is 92.1% and 94.6%, respectively.
