Necrobacillosis
What
is necrobacillosis?
This
is a bacterial disease which is found in wild and domestic ruminants.This
disease is caused by bacteria which are common in the environment
and can also cause foot abscess in sheep and foot rot in cattle. Necrobacillosis
commonly affects young animals and deer fawns appear particularly
susceptible.
Young
deer more commonly show a rapidly developing infection with a high
mortality rate, while older deer are more likely to recover after
a brief illness.
The
bacteria that is responsible for the disease persists in cool moist
environments.
Transmission
of necrobacillosis:
Caused
by the bacteria Fusobacterium (Spherophorus) necrophorus. The bacteria
infect deer through cuts or sores on their feet. Animals in wet,
crowded conditions (like the Mulchatna Herd last summer and fall)
are more susceptible. In the case of deer, outbreaks seem
to be associated with dry conditions when there is overcrowding
around water sources.
Symptoms
of necrobacillosis:
Abscesses
in the mouth, esophagus, rumen, and reticulum or on one or more
feet. The jawbone is often affected giving the appearance of
"lumpy jaw." Occasionally the animal will come up
lame. Generally, the animal will not eat and becomes weak and
dies.
Where
is necrobacillosis
found?
The bacteria occurs worldwide.
Treatment
of
necrobacillosis:
Necrobacillosis can be treated by antibiotics.
Significance
of necrobacillosis:
Necrobacillosis is significant in the livestock industry,
where body condition, and reproductivity are affected.
