Hook Worms in Cattle.
(By DR. CIHARLES F. DAWSON, Station Veterinarian.)
In a recent government report, Dr. C. W. Stiles pub-
lished a comprehensive article upon the hook-worm di-
sease in man. This disease is found oftenest in miners,
brick makers, canal diggers and dirt-eating children. It
has many common names, viz: brick-makers' anaemia,
Egyptian chlorosis, miners'anaemia, Porto Rican anaemia,
St. Gothard tunnel disease, tropical chlorosis, hook-worm
disease. In the older medical works it is known as An-
chylostomiasis. This name has been changed to Un-
cinariasis because the scientific name of the worm which
causes it is Uncinara duodenalls. The 'same genus is
found in cats, dogs, foxes, hogs, cattle and many other
animals; in all of which it causes trouble.
In man the symptoms are anaemia, colicy pains,
emaciation, bowel troubles, sick stomach, dropsy, swollen
feet, loss of appetite, dizziness, low fever. These symp-

toms so much resemble those noted in cattle anaemia or
"salt sick" that the writer embraced the first opportuni-
ty of studying the disease according to the methods 'pur-
sued by Dr. Stiles in his observations upon the hook-
worm disease in man.
Although a former article expresses the belief that
"salt sick" is chronic Texas fever, the subject is by no
means closed, and it may yet turn out that there are
several causative agents. Time, with material and op-
portunities for such research are required, and until these
are provided, all statements concerning the cause of the
disease are considered as preliminary ones.
Many requests for information upon the cause and
treatment of "salt sick" are received, and it seems our
duty to keep the public informed of any discoveries made
along this line, in the hope that the remedies recommend-
ed will be given a trial, and the results of their use be
communicated to this department.
Recently large numbers of pin-sized and microscopic
worms were discovered in the intestine of a salt-sick calf.
The same worm was discovered in a herd of 200 sick cat-
tle, in Gadsden county. The loss was 75 head at the
time of my visit. Specimens of the worm, which closely
resembles the hook-worm of man, were sent to Dr. Stiles
at Washington for diagnosis. He kindly reported that
worm was the hook-worm of cattle, Uncinaria radiata.
As it is conceded that the hook-worms, when in large
numbers, always cause trouble by biting and sucking the
blood from the mucous membrane of the intestine, and
probably the secretion of an irritating and poisonous sub-
stance, it now remains to establish a causal relationship
between this worm and cattle anaemia or "sick-salt."
Meanwhile, efforts to discover a specific treatment are
being made, and the several combinations of drugs indi-







cated are here given in the hope that the public will also
try them and report the results.
.11. thi,,,, No. 1. Sulfate of iron, 2 drachms dissolved in
2 ozs. of water, three times a day, for three days. Fol-
low this on the fourth day with a pint of castor oil, in a
pint of milk.
,1, tH /, IN Ao. 2. Give 2 drachms of creolin, or lysol,
in a pint of milk twice a day for two days.
Method NJV. S. Give 50 grains of thymol dissolved in
one quart of a one per cent. solution of coal-tar creosote.
Method VNo. 4. Give one ounce of gasoline dissolved
in milk, or linseed oil, once daily, for three days.
Follow any of these methods with the following general
tonic: Quinine, 1 ounce; sulfate of iron, 2 ounces; nux
vomica, 2 ounces; gentian, 6 ounces. Mix and divide in-
to 24 parts. Give one powder in water, milk or syrup
twice daily.
All doses given are for adults. Reduce to one-fourth
for calves, and to one-third for yearlings. In cor-
respondence, please mention the method tried. A salt
lick composed of salt 100 parts, and of sulfate of iron,
one part, is also recommended.
O State papers please copy notice.
