Answer by o. o. Churchill, assistant
professor of agronomy field crops),

Question-What is blackleg? How
can it be cured and is it contagious?
Answer by L. Van Es. professor Of
veterinary science, Agricultural col
Iege, North Dakota: Blackleg is an
acute infectious disease due to the
Introduction and vital activity of the
blackleg bacillus 1t is characterized
by evidence OF severe acute illness, ac-
companied by swellings OF the mus
cles of the limbs and sometimes OF
the head and neck, and which are IL
able at later stage OF the disease to
show the formation of gas, as evil
denced by peculiar cracking sound
upon rubbing the skin. We do not
know of any cure for blackleg, but
animals exposed to infection can be
efficiently protected from 1t by the
process of vaccination. The vaccine
used for this purpose is issued free
of charge by the United States de.
partment of agriculture upon applica.
ton.
Blackleg is not readily transmitted
from animal to animal, but many ami.
mails may get it from the same source,
and that source is usually the soil, as
blackleg bacillus can maintain its vi.
tality in the soil almost indefinitely.

noticeable phenomena, but in tuber
culous animals the injection will be
followed by decided rise of tempera
ture.
This phenomena depends upon the
