J68 DISEASES OF THE DOMESTIC ANIMALS 



from mange in being more easily cured, in not being contagions, 

 and in the absence of sarcoptes in the skin. 



Follicular mange is caused by the Dermodex folliculorum 

 (var. canis), which invades the sebaceous glands and hair follicles 

 and is very difficult to eradicate. It is prone to attack the head, 

 neck and limbs, and spreads over the body. There is a form in 

 which only bald spots with scaliness about the eyes is seen, but 

 usually it begins with erythema and the formation of papules and 

 pustules with the secretion of pus. The skin becomes much thick- 

 ened and roughened with wart-like nodules from which pus and 

 sebaceous matter may be squeezed, or there may be infection with 

 suppurating surfaces and great swelling about the head. Itching is 

 not so marked as in sarcoptic mange. When the disease is exten- 

 sive it is incurable. 



Mange in Sheep. — See Scab. 



Treatment. — Either form of canine mange is communicable to 

 man (scabies), and isolation of the dog is essential to prevent its 

 spread to other canines. The use of a muzzle and clipping of the 

 hair over the affected areas are necessary. In sarcoptic mange, Peru- 

 vian balsam may be rubbed daily into the diseased skin, or the fol- 

 lowing may be used : Balsami peruviani, 3i, ung. sulphuris, 3vii ; or 

 picis liquidae, §i, sapo. mollis, gi, alcohol, §iv, gives excellent results. 

 Hosts of remedies have been tried in follicular mange, but weeks 

 or months are required for a cure, and even then only in cases of 

 limited extent. The most satisfactory remedies include the follow- 

 ing: The use of a bath, containing y 2 of i per cent, potassium 

 sulphuret, for fifteen minutes daily, followed by rubbing into the 

 skin of pure Peruvian balsam. Creolin is used in various forms, as : 

 ^ Creolini, Tt\, 50, adipis lanse hydrosi, §ii, as inunction ; or creolin 

 in bath (2 per cent.), with local application of equal parts of creolin 

 and alcohol. In either case the local applications should be made 

 once or twice daily. The employment of this prescription has 

 yielded good results when applied daily (Hunting) : I£ Creosoti, 3ii,
