The Sauk Centre herald. (Sauk Centre, Stearns County, Minn.) 1886-current, 1938-04-21

CHIEF OF the bureau OF amman III
dustry of the u. 8. Dept. OF Agri-
culture, has made a recapitulation
of 30 reports from 30 states repre-
senting a total OF 169.204 cases Of
sleeping sickness. In Table II Of
this report 1t is shown that OF TO-
800 horses vaccinated with a double
injection treatment using formoliz-
ed brain tissue thirty days before
the outbreak. only 81 head or fifty
eight hundredths OF one per cent
later developed symptoms OF the
disease. or 1910 animals that
were vaccinated during the out
break last summer, 1912 head or
IL per cent developed the disease,
much higher than when treatment
was administered thirty days before
the outbreak. These results sub
stantially support the claims made
for the vaccination of horses and
mules as n preventative measure
against sleeping sickness. The very
small occurrence Of disease In ear
ly vaccinated animals. gives en-
enlargement that sleeping sickness
can be controlled by vaccination.
For this reason vaccination carried
out during the months OF April.
May and early June should take
place II the damaging results OF
1887 are to be avoided.
Veterinarians who have prepared
the vaccines In the pathological
laboratory OF the federal Bureau OF
Animal Industry at Washington In
February, 1898, reported that they
have carried on numerous expert
ments with the formolized tissue
vaccine that was originated by
them, on n number Of horses, and
that these experiments have con-
clusively demonstrated that vacci-
nation will immunize horses for at
least six months after the second
dose Of the vaccine. This proves
conclusively that vaccination done
at this time will carry horses past
the danger period for 1888.
Is there any danger Of infection
resulting from vaccinationf There
Is no danger OF causing sleeping
sickness with the use of vaccine
originating from reliable source,
The virus In a dependable product
has been killed by the formalin
treatment as demonstrated by ster-
ility tests In the laboratory and
safety tests by guinea pig innocula-
ton before releasing the product
for use.
What after-care should be recon-
mended for vaccinated animals?
No special after-care recommended
lions are necessary except to avoid
as far as possible excessive fatigue
and exposure for a week after vac
cination. Other than slight reac-
lions are seldom observed.
What is a serum. Sleeping sick
ness serum Is the serum part OF
the blood OF an animal that has
been hyper-immunized with the live
germ OF the disease.
Can serum be used rs a preventa-
tiveY Yes, only after the disease
has appeared has II any value, and
then only for a period Of 14-21 days
In most cases this comes too late
and doses repeated frequently
enough to be OF value become very
expensive,
For n number of years now the
federal and state research agencies
have been trying to bring out the
best possible information concern
Ing the control Of the disease. With
so many untested measures now In
practice In some areas OF the coun-
try, a few words OF warning might
be In order. The administration OF
drugs or medicine or the practice
OF bleeding Of animals Is OF very
little value. During the outbreak
In 1887 there were numerous con-
coctions offered to the public for
the treatment Of sleeping sickness
through the states where the dis
ease had become prevalent. Many
thousands OF dollars were spent by
horse owners for these so-called
cures. II Is hoped that everyone
interested will not hesitate to dis
courage the sale and use OF any and
all of these fakes that have recent
