form of preparing roup and chicken pox vaccine consists in pre:
the use of the bacterial vaccine combined with tl1e vaccine pre- I-um
pared from the scabs collected from the combs amd wattles bm-
and the exudate from the eyes, nose and throat. This material CMC
is dried, pulverized and mixed with normal salt solution in 1,1-Ot
the proportion of one gram to 100 cubic centimeters of normal {aka
salt solution. To this amount is added 100 cubic centimeters ing.
of the bacterial vaccine. making at total ol' 200 cubic ceniti- {Od
meters which is sufficient to vaecinate 200 birds. By using and
the bacterial vaccine in combination with the scatbs and ism.
exudate, two doses instead of one can be made from the same HH ,
