954 Scabies. 



so that in severe disease it must be repeated at intervals of 5 to 8 days, as often as 

 4 to 5 times ; moreover, tlie wool is colored lirown by it. 



Ziindel's scab dip is prepared like Kaiser & Ostertag's dip, with the differ- 

 ence however that pure water is used instead of tobacco decoction. In lifiht cases 

 one dipping suffices; in severe cases, however, a repetition of the treatment is 

 necessary. The dip does not affect the wool (acconliug to Ziindel pure carbolic 

 acid is to be preferred to crude, for the oils of tar are also effective). 



Eeceutly Regenbogen has introduced akaprin baths, but Eabiger did not find 

 these sufficiently effective (the authors noticed the same thing in sarcoptic scab 

 of the dog and horse). 



The lime and sulphur dip has recently been used more extensively in North 

 America as well as in the English Colonies, especially in South Africa and 

 Australia. These dips have different constituents, but are generally prepared 

 from sulphur, lime partly slaked and partly unslaked, and boiling water (Salmon & 

 Stiles). The results are quite favorable. 



1. Recently therosot baths have now and again been employed in Germany 

 (1 part of fluid therosot in 4 parts of water) ; in isolated cases, howe^-er, poisoning 

 has been noticed, which is attributable to the mercury contained in the remedy. 

 Especial caution seems to be necessary in the treatment of animals and in sucking 

 ewes. 



After each treatment of sheep it appears necessary to thoroughly 

 cleanse the sheep house and disinfect the gi'ound, the walls and racks. 

 For this purpose the ground is thoroughly soaked with hot lye after the 

 straw and the upper layer of dirt have been removed and before the 

 ground is disinfected. The wooden parts and the walls are also washed 

 with lye and are painted \nth fresh lime. After the last disinfection 

 it is advisable to ventilate the stable thoroughly for two weeks before 

 sheep are permitted to enter it. 



During the treatment as well as previously to it the sheep 

 should, if possible, be fed intensively, for they are much weak- 

 ened by the energetic treatment, and those that are severely ill 

 may be completely exhausted. After the treatment is completed 

 the flock should be w^atched for some time (in Germany a period 

 of 8 weeks is prescribed) in order to determine a definite cure; 

 the disappearance of itching and the even aftergrowth of wool 

 are especially to be noted. 



The treatment of sarcoptic and dermatopliagic scab con- 

 sists in removing the softened crusts and in the repeated dress- 

 ing of the affected parts of the body with anti-parasitic oint- 

 ments and oily substances (see page 951).

(d) Scabies of the Goat. 



Mange of the goat is most frequently caused by sarcoptes 

 scabiei s. squamiferus ; much more rarely is the disease caused 

 by the dermatophagus communis, wdiile dermatocoptic scab (in 

 the external ear passage) has hitherto only been observed by 

 Nallet, Morat and Mense.
