PLEUROPNEUMONIA which has been described as one of the most
serious diseases affecting goats has been reported from several provinces
and has also on previous occasions been investigated at the Imperial Veterinary
Research Institute, Mukteswar. The object of this paper is to record the
results of an investigation on an outbreak of this disease in which the rô1e of
a pasteurella organism as a causative factor has been established.

                              HISTORY OF THE DISEASE

The first outbreak of this disease in a virulent form was reported in 1923
from Garhwal district, practically eliminating the goat population. In 1924,
outbreaks of pleuropneumonia prevailed in Almora district and accounted for
the death of 1,500 animals. Most of these outbreaks remained undiagnosed,
and no organisms of possible etiological significance were isolated. In 1926,
a form of pneumonia was investigated by Cooper in hill-goats, and in this
connection the following is quoted from Shirlaw [1939]: ' Impressed by the
large number of cases of pneumonia spontaneously occurring in goats at
Mukteswar, Cooper conducted bacteriological examination on the diseased
lungs from which he isolated an organism of the pasteurella genus which
proved pathogenic to rabbits. From an outbreak in Garhwal hills he isolated
a similar organism, thus satisfying himself that the disease of goats naturally
occurring at Mukteswar did not radically differ from that reported from the
provinces.' About the same time Haddow [Shirlaw, 1939] investigated the
disease at Izatnagar among the local goats and concluded that the condition
was an acute bacterial pneumonia, the organism involved being diplococcus,
probably a pneumococcus.

During 1937-38, a form of pneumonia in kids was investigated at the
Goat Breeding Farm, Etah, and diagnosed as bronchopneumonia. As all
these cases occurred in winter, chill was attributed to be the pre-disposing
cause. The condition was not investigated bacteriologically and its etiology
remained obscure.

An outbreak of pleuropneumonia which provided material for cultural
and experimental studies appearing in this paper occurred in August 1940,
at the Goat Breeding Farm, Etah. Six animals succumbed to the disease
out of 20 affected in a herd composed of 200 goats. The disease had pre-
vailed among the male stock, affecting only the adult bucks, and the young
