46. Anthrax.—The diagnosis of anthrax is to be confirmed by micros-
copical examination and, in exceptional circumstances, by inoculation.
47. Epizootic lymphangitis.—Cases of epizootic lymphangitis, which
have been confirmed microscopically, will be destroyed, the affected unit
placed in " working isolation " and all wound in-contacts strictly isolated.
The minimum period of isolation for in-contacts is 4 months. All cases of
epizootic lymphangitis will be reported on manuscript form as prescribed
in Appendix E.
48. Glanders.—(i) The Mallein Test will be applied in all outbreaks of
Glanders, or on the occurrence of suspicious symptoms and on the admission
to hospital of an animal showing nasal discharge.
The procedure to be adopted in regard to the Mallein testing of animals
in Remount depots will be as follows :—
Remounts received into a remount depot from overseas.—These
will be
isolated for one month and tested with Mallein during this period not earlier
than the 14th day after arrival in the depot.
Direct Issues.—" Direct Issue " horses sent to a Remount depot for
onward transmission after a short rest will be isolated from other remounts
and if issued to units before the 15th-day after receipt they will not be tested
with Mallein in the depot. " Direct Issue " horses retained in the depot
for a period exceeding 14 days will be tested with Mallein before issue.
Youngstock Horses and Mules.—These will be tested with Mallein imme.
diately on receipt and retested after 3 weeks, should it be impossible to retest
the animals at the time laid down owing to the prevalence of Catarrh,
Strangles or other disease, they will be retained in isolation until they have
been subjected to a second test.
Chargers and animals returned by Officers or Units to a Remount Depot.—
These will be tested with Mallein on arrival, kept in working isolation for
one month and retested after 3 weeks.
A record of all Mallein tests will be kept on the back of each animal's
ticket.
When subjecting animals to the Mallein test, the Introdermal palpebral
method will be used except in such cases where it is more convenient and
economical to use the subcutaneous method.
Animals which give a positive or doubtful reaction to the Intradermal
palpebral test, will be retested by the subcutaneous method within thirty-
six hours.
When a doubtful reaction follows the subcutaneous test, the animal will
be isolated and retested after three weeks by the Intradermal method
followed by the subcutaneous method within thirty-six hours.
Animals showing clinical symptoms of Glanders or giving a definite posi-
tive, reaction to the Mallein test will be destroyed. When animals give
doubtful reactions to the Mallein test, a report will be made to the A. V. O.
concerned for instructions.
(ii) When Glanders occurs in a unit or detachment all possible in-con-
tacts will be tested with Mallein. The test will be repeated after an interval
of three weeks and the unit will not be declared free from the disease until
all in-contacts have failed to react to the second test.
(iii) The operations of a V. O. acting as an inspector under the provisions
of the Glanders and Farcy Act (see Appendix H) are to be confined to the
area within a radius of 5 miles from the station or stations of which he is in
veterinary charge.
