Lung Worms in Swine.
(By DR. CHARLES F. DAWSON, Station Veterinarian.)
Recent study of a fatal disease in swine showed the
cause to be lung worms, named Strongylus paradoxes.
This disease is quite destructive in Florida and is
known popularly as "the pants" or the "thumps:" The
affected animals cough up the worms and their eggs upon
the pasture and into the drinking water, whence they are
taken into the body with the food and drink, and in some
unknown way find their way into the lungs, where they
cause symptoms of suffocation by plugging the air tubes.
The female worm is from one to one and a half inches
long and is about as thiok as an ordinary sewing needle;
while the male is shorter. The severity of the symptoms
is due entirely to the number of these parasites present
in the lungs. When few in number they cause only a
mild cough or bronchitis. In large numbers they may

cause pneumonia or sudden death from suffocation.
Young animals are more susceptible to invasion by this
worm than the old ones ; hence it is most destructive to
In order to prevent infestation, substances which are
poisonous for the worm or its embryos should be placed
in reach of the animals. Common table salt is recom-
mended for this purpose. The animals should be re-
moved from damp pastures and deep well water should
be provided. The diseased should be separated from the
healthy. Those which die should be deeply buried or
burned. In cases where it is undesirable to treat the an-
imals, and where they are of sufficient size, they should
be killed for pork.
The least troublesome and at the same time most suc-
cessful method of treatment is by fumigation, as the
worms are thus stupefied, and coughiug fits are induced,
which expel them. For this purpose may be used rags,
horns, feathers, hair, leather, tar, juniper berries, asa-
foetida, or equal parts of tar, sulphur and turpentine.
Put the'animals in a close room, suspend by a chain an
iron pot of burning charcoal, and pour on the tar, sul-
phur and turpentine, or place upon the live coals any of
the above substances in sufficient quantity to thoroughly
fill the room with the fumes. Close the door and allow
the animals to be exposed to the fumes for twenty-five
minutes. Repeat the process on three different dlays.
Pour hot water on the floor to kill the worms which have
been expelled.
