(11) Re-vaccination.— Details
are given in Table VI. The total number of
re-vaccinations done during the year was 544,979 as against 430,922 last year
and 389,307 the previous year. There has thus been a progressive increase in the
number of re-vaccinations. The case and insertion-success rates were 30.7
per cent and 19.7 per cent, respectively, the figures for the last two years being 30.8
per cent and 18.8 per cent, and 30.1 per cent and 18.4 per cent, respectively.
There has thus been no material change in the case and insertion-success rates
for re-vaccination during the last three years.
(B) STOCK VACCINES, SERA AND MISCELLANEOUS SUPPLIES.
(1)
Charge of work .—Assistant Surgeon S. R. Pandit, and later and for most
of the time, Military Assistant Surgeon F. G. Martin have been in charge.
(2)
Cholera vaccine .—Modified Douglas agar has continued to give satisfactory
results. The total quantity issued, 381,350 cc, is smaller than the issues of the last
two years because cholera was less prevalent.
(3) Other stock vaccines .—Details are given in Table VII. The most note- -
worthy feature is the great increase in the demand for gonococcal, staphylococcal,
streptococcal, puerperal mixed streptococcal and B. coli vaccines, showing that
these vaccines prove useful in treatment. The amount of these vaccines made
this year is about three times the amount made four years ago. We are informed
by some medical men that our vaccines prove superior to those on the market
prepared by commercial firms. This is probably due to the fact that we use
local strains and are in a position to constantly get new ones. Vaccines such as
gonococcal represent a considerable amount of work because the organisms are
hard to grow.
(4)
Sera for human use .—Details are given in Table VIII. The demand still
shows the same steady rise from year to year. This year's amount is 25 per cent
more than last year's. As far as possible concentrated sera are bought. The
main bulk of the supply has been from the Lister Institute, London.
(5)
Veterinary Sera .—Details are given in Table IX. The volume dealt with
has increased enormously. It is 50 per cent more than last year's total and is
now more than we can properly cold-store.
(6)
Miscellaneous supplies.— Table X shows the usefulness of the Institute to
Hospitals and Laboratories in supplying solutions for injection, media, special
reagent, cultures, etc.
(C) CLINICAL BACTERIOLOGY.
(1) Military Assistant Surgeon J. H. Theodore was in charge of this section
for 10 months of the year and the Second Assistant Director Dr. T. Sithapathi
Ayyar for the rest of the time. They have assisted in writing this report.
(2)
Autogenous vaccines .—Details are given in Table VII. The demand has
continued to increase—it is 20 per cent more than last year. The analysis in
Table XI of the few returns received shows benefit in two-thirds of the cases. In
the treatment of chronic rheumatism autogenous vaccines made of Streptococci
isolated from the teeth, etc., were formerly used, but with indifferent results.
Prof. Warren Crowe's work on the bacteriology of rheumatism has been taken
advantage of. With the aid of his special blood medium—"Chocolate Medium"
Staphylococci isolated from pathogenic discharges have been classified into differ-
ent types of which " Micrococcus Deformans " appears to have been the causative
