Contagious Pleuropneumonia of Goats
muscularly gives rise to an acute, progressive, and usually fatal oedema at the site of the
inoculation, with death in 3 to 10 days
6. The inoculation of effusions from these lesions give rise to similar lesions in.
other healthy goats
7. Pleuritic and pneumonic lesions can be induced by direct extension from similar
lesions in the musculature and connective tissues in the thoracic wall.
8. The pneumonia can regularly be induced by the intra-nasal insufflation of either
pneumonic lung emulsion or effusion from local reactions.
9. Guineapigs and rabbits have in no instance evidenced any reaction to
inoculation.
10. Immunization with formalized vaccine in the face of outbreaks have given very
good results in checking the spread of the disease.
11. Five goats out of twelve experimental goats, receiving virulent inocula intra-
nasally, subcutaneously or intra-muscularly aborted, i.e. there were 4l.6 per cent abortions.
Only in one case the serum was found to be doubtful against A and positive against M
for Brucella infection; all other samples of the serum were found to be negative for
Brucella infection.
12. All the experimental evidence tend
to show that the contagious
pleuro-pneumonia as found in Sind is identical to that of Madras described by
Longley.

APPENDIX A
Tachnique for the preparation of vaccine for contagious pleuro-pneumonia in goats in the field
Infected goat should be selected, i.e., one that is showing temperature of 104° to 106° (higher the temperature
the better) and this should be slaughtered in a clean place.
Dead goat should not be used for the preparation of the vaccine.
Expose the lung carefully and select a recent lesion from the pneumonic lung. By recent lesion is meant, a
lesion which is not gangrenous or suppurating and is generally found on the edges of old lesions.
About 4 gm. of this is required for every hundred goats. Remove the required portion of the pneumonic lung
with a sterile pair of scissors and forceps and place it in a sterile and clean mortar. The pieces of lung then
should be cut into small bits by means of scissors.
These pieces should be thoroughly grounded up by means of stone pestle and mortar and gradually 100 c. c.
of normal saline should be added. Filter it through clean muslin.
To every 100 c. c. of prepared vaccine and 1 c. c. of liquor formaldehyde B. P. and shake well.
Dose. For adult goat 1 c. c.
For 6 months old or under ½ c. c.
Site. Region of neck, to be given subcutaneously.
Diseased goats, i.e. those showing clinical symptoms and temperature of 103° or above, should not be
vaccinated.
Results should be checked after a fortnight.
