Besides the treatment of the patient it is always advisable

Fsoroptic Mange. — This form of mange occurs in the 

 most protected parts of the body, such as the mane, tail, 

 sheath, medial surface of the hind limbs, region of the throat, 

 etc. It may, however, spread over the whole body thus, 

 resembling sarcoptes mange. 



Diagnosis. — The diagnosis is made with the microscope. 



Prognosis.- — The prognosis is more favorable in this than 

 in the sarcoptes form, as the mites are on the surface. How- 

 ever, especially in cold weather, which interferes with the 

 application of the treatment, the case may prove obstinate. 



Treatment. — Treatment is the same as for sarcoptic mange. 



Symbiotic Mange. — This form occurs about the fetlocks, 

 especially under the flexion of the joint. 



Symptoms. — The symptoms are similar to those of scratches 

 (squamous and crustated eczema), but the affected parts are 

 itchy, causing the animal to gnaw them and stamp its feet. 

 At times the lesions may extend up the leg to the tarsal or 

 carpal joints, but rarely higher. 



Diagnosis. — The diagnosis is made with the microscope. 



Prognosis. — Prognosis is favorable. 



Treatment. — Usually a creolin salve or a tar salve suffices 

 to produce a cure. 



Sheep Scab. — Mange of Sheep. — The most common form 

 of mange in sheep, so-called sheep scab, is psoroptic mange. 

 However, the sarcoptic and symbiotic mites also attack 

 sheep.
