Sarcoptic mange
Sarcoptic mange is cause by the mite Sarcoptes scabiei which burow
into the skin causing intense irritation. Infection generally
starts on the legs and face but can extend over the whole body.
Female adult mites burrow tunnels in the skin in which they lay
2-3 eggs per time. These eggs hatch after 3-5 days into larvae
which then burrow into side tunnels or travel to the skin surface
and make new tunnels. The larvae molt to form nymphs which then
develop to adults. The whole cycle takes around 14 days. female
s will continue to lay eggs for 2 months. All stages of sarcoptes
are susceptible to drying and will only survive for a few days
of the animal. Spread to other animals is via directed contact.
Microscopic examination of skin scrapings is used for diagnosis
of sarcoptes. Weekly insecticidal rinses containing malathion or amitraz are
used to treat sarcoptic mange. More recently Ivermectin given
orally or by injection has been used as an additional treatment. Related sites |
