PAEASITIC FUNGOID DISEASES OF ANIMALS. 



Favus {Achorion .^chognleini I) in Poultry. 



Information was asked concerning the advisaliility of eating fowls 

 snffering from " Favus." 



"It is scarcely advisable to eat diseased fowls, but the chances 

 of any harm arising from ' Favus '-diseased birds when cooked would 

 be very slight. 



" This parasite that causes the white-comb is only, I believe, found 

 on the skin, nails, etc., of man and does not attack him internally. 



" Birds in the early stages of the disease frequently do remarkably 

 well, but as it increases they lose condition and may eventually be 

 killed by it. 



" Young l)irds are fi-equently affected and might easily contrnct the 

 disease from the parent ; but eggs from the affected birds would not 

 give rise to ' favic ' young. Unless they came in contact after 

 hatching with tlie diseased parents or other afHicted birds or animals 

 the young would not be diseased.' 



Ringworm {Tinea tonsurans;) in Calves. 



Concerning this disease in stock advice was sought by tlie Board. 

 The following notes were despatched : — 



1. With regard to Ringworm in cattle it is well known that it is 

 fairly general in parts of this countiy. 



2. A number of attacks have recently Ijeen noticed, and when 

 pointed out, the owners in all cases said that unless the disease 

 became very general over the beasts they took no notice but let it 

 die out. If the diseased areas spread very rapidly, smearing with 

 sulphur and lard or sulphur and soft soap soon destroyed it. Several 

 cases kept under observation certainly i-apidly disappeared with this 

 treatment. 



Treatment. 



Two substances that could be used upon animals which act Well 

 in treating human subjects are iodine and oleate of copper. 



The iodine is used as an ointment, also the oleate of copper (1 part 

 to 5 parts of lard). Oleate of copper can be obtained from chemists ; 

 it is often recommended for human ringworm, but is not an official 

 medical remedy. 



As a lotion, sulphurous acid and glycerine may be used with 

 advantage at the rate of one fluid drachm of acid to three fluid 

 drachms of glycerine.
