TREATMENT OF MANGE AND SCABIES 131 



though, due to the intractability and habits of pigs, there is probablj- 

 even less prospect of a complete destruction of the mites. The presence 

 of Demodex, however, is rarely recognized in pigs, and the effects it 

 may produce are far less serious than in dogs. 



Treatment of Otacariasis of the Dog, Cat, and Rabbit 



Clean the ears of dogs and cats thoroughly and deeply with olive oil. 

 It may be applied with a bit of cotton rolled upon a probe which should 

 be rotated as it enters the deeper parts. Nocard's treatment, as stated 

 by Neumann, is as follows: Naphthol 1 part, ether 3 parts, olive oil 

 10 parts. Inject into the external auditory canal each day. After in- 

 jecting close the canal for ten to fifteen minutes with a pledget of cotton. 

 This is to prevent the evaporation of the ether. The ether causes the 

 remedy to penetrate the wax>' Iming of the canal which contains the 

 parasites. 



In the treatment of ra))bits the scabs are first to be softened by a 

 thick lather of soft or green soap which should be allowed to remain for 

 an hour, rinsed, and repeated as ma}' be necessary for deep crust forma- 

 tion. The deeper parts of the ear ma}' then be cleaned with olive oil 

 and cotton as directed for dogs and cats. 



As an acaricide, the same treatment may be employed as recommended 

 for otacariasis in dogs and cats, applying the remedy with a pledget 

 of cotton over the whole inner surface of the concha as well as injecting 

 it into the auditory canal. An ointment of sulphur, or a liniment com- 

 posed of benzene and olive oil equal parts may also be used, either to 

 be applied with a pledget of cotton rolled upon the end of a probe or 

 stick. 



It is a good precautionary measure to treat the ears of all rabbits 

 which have been exposed, as there ma}^ be infections of a latent char- 

 acter which will later bring about another outbreak of the disease.
