a "continuous feeder", whereas examination of a collection kindly sent
by the Veterinary officer at Mhow revealed the fact that both B. australis
and Hyalomma aegyptium, an "interrupted feeder", were present upon
that farm. Incidentally a special consignment of ticks sent in a sepa-
rate bottle was received from the Mhow farm, together with blood
smears from the animal, from which these particular ticks had been
collected since it, a country-bred bull, was at the time exhibiting fever.
These ticks proved to be B. australis and the blood smears showed a
relatively rich infection with B. bigemina.
IX.—BOVINE NASAL GRANULOMA.
(1) Jubbulpore outbreak.—The occurrence of a large number of cases
of this disease among the cattle at the Military Dairy Farm, Jubbulpore,
was brought to our notice during the year by the Veterinary Officer in
change, Major G. E. Oxspring, R.A.V.C., which resulted in my visiting
the farm in July 1930 to carry out an investigation with him. It was
not possible to determine at all accurately for how long the farm had been
affected, or from where the disease had originated. An enquiry made
through Major W. H. Priston, Officiating Director, Civil Veterinary
Department, Central Provinces, showed that, although cases of the
disease were known to occur in the Province, it did not appear to be
either widespread or of very common occurrence in the local cattle.
Since cattle had been introduced to Jubbulpore from South India and
notably from Bangalore, where the disease is certainly very widespread,
it appears possible that it might have been introduced with these
animals. Examination of the available records indicated that of the
affected animals then present at Jubbulpore none had become affected
under the age of 20 months, or in a less period of time than 12 months
residence on the farm. These facts may serve as a guide to the prob-
able incubation period of the disease.
Of the cattle present (nearly 170) upon the Jubbulpore farm in July
1930, 60 per cent. of the cows and 50 per cent. of the total animals were
affected. Active steps were taken to carry out treatment with Tartar
Emetic and, after preliminary trials, a dose rate of ten grains in 20 c. c.
of water given every three days until ten injections had been adminis-
tered, was decided upon. At the time of my visit this treatment was
beginning to show results which indicated clearly that any less number
of injections than the full course permitted a recurrence of the disease
within a relatively short time of a few weeks only. Treatment was
accordingly repeated upon the animals and in January 1931. there was
not a single animal remaining affected with the disease.
This striking proof of the efficacy of tartar emetic in the treatment
of the disease reduces to a very great extent the importance of bovine
nasal granuloma as a disease of serious economic importance in India,
but on account of the large number of repeated injections necessary,
and the recognised difficulty in carrying out continuous intravenous
injections with this highly irritant drug, it is very far from being ideal.
With a view to carrying out research in this connection, six badly
affected animals were obtained from the Jubbulpore farm and they are
