PART V.

A PECULIAR FORM OF STREPTOTRICHOSIS AMONG
                                    CATTLE.

DURING the past year a disease bearing a resemblance
in many clinical features to equine epizootic lymphangitis made
its appearance among the Army Transport Bullocks in Calcutta.
In October 1907, we were requested by the Senior Veterinary
Officer of the Division to investigate the etiology of the disease.
Captain Edwards, A.V.C., kindly supplied the material, clinical
notes and photographs of the cases. The Laboratory work
was carried out by Mr. Cross, Assistant Bacteriologist and my-
self.

                      HISTORY OF OUTBREAK.

The first case occurred in November 1906, in the Transport
Lines at Hastings (a suburb of Calcutta). No further cases
were observed till April 1907, and between that time and the end
of December 1907, eighty-five bullocks were affected. Of
these eighty-five cases, eighteen were destroyed as incurable,
thirty-eight have apparently recovered, and twenty-nine still
remain under treatment. From the dates of the second cases
in April, all Transport bullocks were kept under close observa-
tion and at the first appearance of a sore or any enlargement
of the gland, the animal was immediately segregated and placed
under treatment.

                                SYMPTOMS.

The first symptom which attracted attention was usually
the appearance of a small nodule under the skin in the region
of the neck, shoulder, ribs or flank. This was followed after
a period varying from a few days to some weeks by enlargement
of the deeper seated glands, almost invariably the prescapular
or precrural.

This was accompanied by pain and inflammatory swell-
ing in the affected part and generally marked lameness.
