PARASITES AFFECTING THE SKIN 41 
smaller varieties of dogs and in cats ol. anisi or ol. 
eucalypti in spirit are best, though these do not neces- 
sarily destroy the parasites. 
All mats and bedding should be destroyed, and 
kennels disinfected and limewashed. 
Cutaneous Filariasis. 
In Russia, Hungary, and some few other countries, 
horses, more particularly thoroughbreds, often exhibit 
symptoms of what is known as “ parasitic skin-bleed- 
ing.” 
The cause is a worm, either Fularia multipapillosa or 
Filaria hemorrhagica. ° 
Filaria multipapillosa is from 2} to 23 inches in length. 
Its cephalic end shows a series of papille, arranged in 
rows, from which it derives its name. The body is 
transversely striated. Within the nodules the worm is 
coiled into a spiral. It is ovo-viviparous, and is prob- 
ably carried to various parts of the body at some stage 
by the blood-stream. 
Symptoms.—These are more apparent in warm 
weather, and may recur during several successive 
summers. 
Non-inflammatory nodules about the size of a pea occur 
on the neck, shoulders, and breast. From these there 
exude drops of blood at intervals. The hair becomes 
matted, and after a while streaks of blood are seen on 
the skin. The general health is unimpaired. They 
often cause inconvenience owing to their position under 
the harness. 
Treatment.—Clip the part, and apply alcohol or tinct. 
iodi. Any parasiticide may be employed. Arsenic 
should be administered internally. 
In Hungary the swelling is incised, and the worm 
extracted just at the time when it is about to open.
