130 PARASITES OF THE DOMESTIC ANIMALS 



larger surfaces of the body. Strong tobacco decoctions, benzene, or oil 

 of turpentine may be used, the latter shaken up in an equal quantity 

 of linseed oil. Equal parts of kerosene and linseed oil also give good 

 results. Two or three applications of the remedy applied several days 

 apart usually suffices to bring about a complete cure. 



The usual precautions against reinfection should be observed. The 

 bedding is to be burned and utensils disinfected. Animals should have 

 their legs regularly and carefully groomed, and attendants should 

 be on the lookout for symptoms of a return of the affection. 



Treatment of Chorioptic Scabies of Cattle. — The curative procedure 

 for this scabies does not materially differ from that for bovine mange. 

 As chorioptic scabies appears upon parts which may be reached by 

 the tongue, preparations containing active poisons should be avoided. 

 Probably an ointment of sulphur, as sulphur one part, lard four parts, 

 or sulphur two parts, potassium carbonate one part, lard eight parts, 

 is most suitable for such cases. 



Treatment of Follicular Mange 



Treatment of Follicular Mange of the Dog. — Owing to the intra- 

 cutaneous location of the parasites, successful treatment of this mange 

 is made very difficult. The prospects for eventual success will depend 

 much upon patience and perseverance. It is important that the general 

 condition of the animal be built up as much as possible by nutritious 

 food and thoroughly sanitary surroundings. Such treatment as may 

 be adopted must be prolonged and often repeated if carried out to 

 effectiveness. The remedies given below for the destruction of the 

 mites are among those which have been tried. The best that can be 

 said for them is that they have sometimes given good results. 



(1) Peruvian balsam 2 parts, creoUn 1 part, alcohol 20 parts. An 

 objection to this remedy is its expense in view of the prolonged treat- 

 ment required. (2) Creosote 1 part, olive oil 15 to 20 parts; (3) benzine 

 1 part, olive oil 4 parts; (4) creolin 1 part, green soap and alcohol of 

 each 3 parts; (5) repeated applications over limited areas of tincture of 

 iodine. (6) In the clinic for small animals at the School of Veterinary 

 Medicine, University of Pennsylvania, some encouraging results have 

 been obtained from the use of ichthyol, prepared with lard or lanolin 

 in the proportion of one to seven. 



Fleming advises that the topical treatment be accompanied by the 

 internal administration of sulphur in frequent and large doses; the sul- 

 phur being excreted to some extent by the skin. 



Treatment of Follicular Mange of Swine. — Treatment of this form 

 of mange in the pig is rarely called for. If there are perceptible indica- 

 tions of its presence a treatment as recommended for dogs may be tried,
