Question-What Is blackleg? How
can 1t be cured and Is it contagious?
Answer by L. Van Els, professor Of
veterinary science, Agricultural COL
lege, 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, &C.
companied by swellings of the mus.

the head and neck, and which are II.
able at later stage of the disease to
show the formation Of gas, as evil
denced by a 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 1t from the same source,

noticeable phenomena, but in tuber.
culous animals the infection will be
followed by a decided rise Of tempera-
