More on Mites

[Guest guest]

I just recently came across a gold mine of a site dedicated to

parasites. It has anatomy, life cycles, descriptions, and more. Hope

everyone can find it useful.

Psoroptic mange is a serious disease in cattle and sheep, less so in

horse and goats. The causative mites are species of Psoroptes and are

host specific. Mites penetrate the epidermis to suck body fluids, and

cause a local reaction with formation of vesicles. The exudate from the

vesicles coagulates and dries on the skin surface, resulting in the

formation of a crust or scab of varying thickness. The mites move to

the edge of the scab, and the lesion increases in size. There is marked

pruritus, and scratching results in alopecia, erosions and

lichenification. Lesions usually begin in areas thickly covered by hair

or wool.

This describes my lesions on my lower arms and etc. Some of them

enlarged to a size of more than 7 cm long and 5cm wide at the worst of

all this.
