lions there is generally found a fibrinous covering which can be scraped off.
'file mucous membrane of the bowels is red and inflamed. When death has
rapidly taken place such inflamation will occasionally be found only in the
stomach and small intestines.
The glands in the mesentery are swollen and dark. The spleen is
apparently unchanged, oscasionally slightly swollen and soft. Very frequently
there is inflamation of the lungs. In the pleura and pericardium often fibrinous
exudations. on the coatings of the heart, both external and internal, there are
often bloody effusions. tf the gullet and tongue be removed the above named
incrustations will be more clearly seen than during life.
The disease lasts, as a rule, from 2 to 3 days. It can however assume a
lasting chronic form, during which the animal is apparently well, and yet has
large incrustations and sores in the bowels, which may be discovered when
the animal is slaughtered or dies.
The incubation of the virus in the body, previous to the outbreak of the
disease, is, generally, from 2 to 8 days.
The disease originates from a little plant which can be discerned by
microscopic examination. This plant will, during the disease, be found in the
stools of the animal, in its blood and most of its organs.
The disease may be confounded with another malignant sickness in pigs,
which is met with in this country, namely, red sickness or anthrax-like
erysipelas. Animals attacked by red sickness die however much faster (in
from half a day to 2 days), are much redder on the body and do not
have any loose discharge from the bowels.
The germs of infection of Swine fever are of very strong vitality. They
are conveyed from the sick to healthy pigs in food, dung, bits of earth, food
utensils, implements and the like.
Should any ease of sickness appear in a stock of pigs, which leads to
the supposition that it is Swine fever, a qualified Veterinary Surgeon must at
Once be summoned, or information thereof be given in towns, to the Chief
Commissioner of Police, in the country to the District Head Constable. In the
meantime no animal may be brought to, or removed from the property.
The Veterinary Surgeon ought at once to dissect and carefully examine
the animal if dead. Should no animal have died, a sick one ought to be
slaughtered and dissected provided the owner gives his permission. Should the
disease prove to be swine fever, the following rules ought to be observed.
No pig may be removed from the property, or any new pigs be brought in.
Raw portions of pigs' flesh must not be taken away. The flesh of sick or
dead pigs ought not to be eaten but buried. Every person who has been in
contact, with sick animals, or those suspected of being attacked, must be
carefully purified. All dung must be carefully removed and buried under at
least 4 feet or earth, and likewise a dead animal in its entire condition if no
dissection is to be made on it. If possible lime should be strewed over it.
All used litter must be burnt.
