NecrObacillOsis in swine

The bacillus necrophorus is the spe-
cifc cause of numerous diseased candi-
ions of domestic animals. Diseases
and diseased conditions of swine, due to
his organism are numerous, and in the
past some Of the LESSONS of necrohacll-
losis were thought to be due to hog
cholera. As rule, necrobacillosls of
swine is a chronic condition, but some-
times it takes an acute and rapidly fatal
course. The most commsnly known
conditions coming unber the term. ne
crobacillosis, are;
Necrotic stomatitis and necrotic rhi-
uitis usually affects suckIings, but
sometimes mature hogs. 1t is frequent
lV termed "sn,fl ss, or "bul nose" BY
the laymen. 1t is characterized by ne
crotic liberation of the lips, nose.
tongue and mucus membranes of the
mouth. Oftentimes destruction to the
gums is so great that the teeth are ex-
posed. As a result of this necrosis
feeding is impossible, due to the pain
and impaired prehension and deelution
and death results from auto-intoxica-
tion and starvation.
Necrotic pharyngilis, necrotic ESQ.
ehaeostitis, and necrotic gastritis are
rare shd may oaIy he the result Of ex
tension of the disease, necrotic stoma-
tits.
Necrotic enteritis or necrotic intestinal
liberation has been considered in the
past to he LESSONS of chronic hog cholera.
The lucrative LESSONS are mostly found
in the large in,estlnes, rarely in the
small intestines. and may involve only a
small surface of the mncus lining of
the large lntestines or may involve the
entire large intestine. Nearly always
with this disease are hemorrhagic areas
in the lymynatics, kluneys and lungs,

the disease over the larger per cent of
the herd.
On a whole, this disease is fatal in
from one to seventy per cent. of the
cases, depending upon the form of the
disease, the severity Of the disease and
the condition of the hogs at the time
they contract the disease.
According to official reports, thes state
