Prophylaxis. Favus. 917 



stables by daily sprinkling of gypsum will promote the favor- 

 able effect of treatment. 



Prophylaxis. Even in a slight outbreak of the disease in a 

 large establishment the affected animals should be isolated, and 

 as far as possible placed in a stable by themselves. If this is im- 

 possible contact with the other annuals should be prevented by 

 leaving an open space between the healthy and the sick animals, 

 by isolating the stalls and by properly tying the animals. Ani- 

 mals suspected of l)eing infected, and especially newly bought 

 animals, should be kept isolated for 8 days; they should not 

 be groomed and should be sheared immediately after stabling. 

 The attendants should l)e taught the initial symptoms of ring- 

 worm wdth a view^ to early treatment. Cleaning utensils should 

 be burnt or disinfected, the bedding is to be destroyed or taken 

 away, the stal)le to be thoroughly disinfected and freely venti- 

 lated. 



Renter and Buseh advocate compulsory notification of ringworm in 

 cattle, detention of affected animals at the borders, and compulsory treat- 

 ment, but Frohner does not consider this to be advisable at present.

19. Honeycomb Ringworm. Favus. 



(a) Favus of Mammalians. 



{Wahen<irin(l [German] ; Dermatomycosis acliorina, Tinea 

 favosa; Te'ipne faveuse [French].) 



Favus of mammals consists in the formation of disc- 

 sluipod, thick scabs on the skin, depressed in the center, l)oing 

 for that reason saucer or shield shaped. They are sulpliur- 

 yellow towards the center and are caused by a filament fungus 

 designated as Achorion Schonleinii. 



History. The favus fungus was discovered in man by Sehonlein 

 (1889). and later Remark (1840) gave it the name of Achorion Schon- 

 leinii. while Gudden (1855) established the fact that the achorion 

 fungus was the sole cause of favus. Jaccjuetant (1847) first mentions 

 favus of the cat without, however, furnishing proof that the disease in 

 c|ueslion was favus. The occurrence of favus in tiie cat was first proved 

 with certainty by Draper (1854) and traced to infection from mice
