COMPARISON BETWEEN THE CORPUSCULAR CHANGES OBSERVED IN THE BLOOD OF EQUINES,
BOVINES, BUFFALOES, ETC., DURING A PERIOD OF OBSERVATION, AND THE PHASES OF SURRA.
If the percentages of the different corpuscles present in the blood of Bovines and
Buffaloes in the massed periods of Surra be compared with similar returns recorded in
equines* (horse and mule), it will be seen—
(i) That like results were noted in all the animals with regard to the percentage
of red corpuscles present during the phases of the disease, i.e., an augment-
ation in the number of red corpuscles during the latent period, as compared
with the number registered in the period of observation, followed by a dimi-
nution in the paroxysms, which was still more marked in the intermissions.
(ii) In the case of the white corpuscles, during the latent period, a diminution
varying from 8.8 to 25.4 per cent. took place in the equines, and 5.9 per cent.
in Buffalo I, but in the blood of Bull V and Buffalo II an increase occurred
in the number of corpuscles equal to 23.3 and 36.4 per cent. respectively.
During the paroxysms and intermissions there was a general increase in the
number of white cells, varying from 0.69 to 84.8 per cent. in all the
animals with the exception of Bull V, and in this case a diminution equivalent
to nearly 10 per cent. was noted during the intermission.
(iii) With regard to the percentages of the coarsely granular cells in the equine,
bovine and buffalo species, a considerable difference has to be recorded, viz.,
a general diminution in the number of corpuscles in the horse and mule
during the different phases of the disease, latent period, paroxysms and inter¬
missions, whereas with one exception (Buffalo II, paroxysms) there was a
marked increase in the number of Eosineophile cells in the buffaloes and the
bull during analogous periods.
Another point of considerable interest is that whereas the above mentioned corpuscles
are absent from the blood, in the great majority of instances, at the time of death or some
days before, in buffaloes their number is augmented to three or four times that noted
during health. The same marked increase in the number of Eosineophile cells is also
observed in bovines during the course of the disease, but in India up to the present these
animals have not been observed to succumb to uncomplicated Surra.
During the course of Surra in the guinea-pig, a gradual diminution in the number of
the red, white and Eosineophile corpuscles was observed to take place in the latent period,
paroxysms and intermissions, with the exception that during the latter massed periods there
was a slight recrudescence in the number of coarsely granular cells, but the percentage
even then was less than half that noted in health.
In the following table the percentages of the coarsely granular cells noted in equines
and guinea-pigs are placed side by side for reference with those obtained in buffaloes
and Bull V :—
