210 Studies on a Natural Outbreak of Pigeon-Pox
COMPLEMENT FIXATION TESTS
Sera from natural cases of pigeon-pox and pigeons after artificial infection
with the English strain were tested for the presence of complement fixing
bodies. The tests were controlled by healthy sera. Kolmer's [1931] technique
of the " Wassermann test" was employed with slight modifications as required.
The results are tabulated in Table VI.

N.B. + = Fixation of complement (no haemolysis).
— = No fixation of complement (haemolysis).
From the above table it appears that the complement fixing bodies are
not, as a rule, demonstrable in the serum of pigeons recovered from pigeon-
pox. Hence this test cannot be applied with advantage in this disease
caused by either the English or the Indian strain of the virus.
