REPORT ON THE WORKING OF THE MICRO-BIOLOGICAL SECTION
OF THE KING INSTITUTE OF PREVENTIVE MEDICINE, GUINDY,
FOR THE YEAR 1920.
Major J. Cunningham, I.M.S., was in charge of the Institute till the 7th March
1920, Major Wright, I.M.S., from 8th March to 30th April 1920, and M.R.Ry.
Rao Bahadur M. Kesava Pai Avargal, M.D., from 1st May 1920 to the end of
the year.
The report of this year has been drawn up in the same form as was adopted
for 1919, part I dealing with the bacteriological diagnosis and treatment of
disease and part II with the examination of water-supplies and all other subjects
connected with the public health.
PART I.
(1) The Preparation and Supply of Bacterial Vaccines.
The number and doses of autogenous and other bacterial vaccines issued
during the last five years are shown in Table I.

The large drop in the total number of doses issued as compared with 1919 is
due to the much smaller amount of cholera prophylactic vaccine issued during the
year. The various medical officers who indented for the vaccine on a large scale
late in 1919 apparently used up their supplies early in 1920, so that the demand
for the vaccine in the latter half of the year was very limited. Cholera moreover
prevailed to a much less extent in 1920 than in 1919, but seems to be showing
signs of its appearance in epidemic form in many localities in January 1921. It
is very likely, therefore, that the prophylactic vaccine will be requisitioned on a
large scale in 1921.
The demand for prophylactic influenza vaccine was larger during the year
than in 1919, though the epidemic was milder. The figures received from different
parts of Southern India, including jails and other institutions, of the prophylactic
value of the vaccine against influenza, showed that though there was no apparent
decrease in the incidence of the disease, there was an appreciable lessening of the
mortality and the pulmonary complications. (Vide Table II.)

and the prolonged contact of the serum with the clot and perhaps, in a few cases,
to want of sufficient attention to the rules of asepsis in the extraction and despatch
of the blood sample in the glass capsule, as many as 27 samples reached the
laboratory in a lysed condition unfit for subjection to the test.
The reagents for the performance of the test were originally got out from the
Central Research Laboratory, Kasauli, but are now being prepared at this
Institute itself.
Macerated fœtera.—Fifty-nine samples were received for examination for
spirochætes, with nine positive findings (vide Table VII). The investigation of
detecting the infection in the mother by a Wasserman test and trying to correlate
it with the presence of spirochætes in the liver of the fœtus was continued. It
was possible to collect the blood specimens of the mother in only 36 out of the 59
cases. In 18 out of these 36 cases the Wasserman reaction was positive, but only
four of these fœtera showed spirochætes. The blood of the mothers of four other
fœtera showing spirochætes could not be obtained for examination. In the ninth
and last case where spirochætes were present in the fœtus, the mother's blood
gave a negative Wasserman reaction.
The above results show that failure to find spirochætes in the liver of the
macerated fœtus does not exclude the possibility of syphilis being the cause of the
condition, for in 14 cases where the mothers' blood gave a positive Wasserman
reaction, the fœtus did not show any spirochætes.

Note .—In the remaining 19 cases the examination for spirochætes was negative and the mother's blood was not
received for examination.
(3) Assistance to other departments.
Veterinary sera and products were as usual, stocked for the Civil Veterinary
Department in the cold room of the Institute and issued as required from time to
time on receipt of indents from that department.
The monthly classes on plague inoculation started in 1918 under G.O. Mis.
No. 285, Medl., dated 18th June 1918, continued to be held regularly during the
year, 110 medical men (Assistant and Sub-Assistant Surgeons) and one lady
apothecary undergoing the course.
Three medical officers of Government were given a course of training in
Laboratory work, as shown hereunder:
—
Temporary Civil Assistant Surgeon M. Govinda Pillai for 2 months.
Do.
do.
A. Narasinga Rao for 3 months.
Permanent Civil Assistant Surgeon. T. S. Ramaswami Pillai for 3½ months.
Further, at the instance of the Mysore Government, Assistant Surgeon
C.Balakrishnan attended the Institute for a period of 3 months to learn the
methods employed in clinical and bacteriological diagnosis of disease.
(4) Research Work.
On account of the heavy routine work of the laboratory, very little time
could be spared by the members of the staff for research work on the medical
side. A series of cultivations from the peripheral blood of cases of Kala-Azar
were made by Dr. T. Sitapathi Ayyar with a view to estimate the reliability of
this method in the diagnosis of the disease. A note on these experiments is
appended (vide appendix V). It will be seen that, as in previous years, the
attempts made in this laboratory to cultivate the flagellates from the peripheral
blood have not been very successful, only 2 out of a total of 18 cases having
given a positive result.

PART II.
PUBLIC HEALTH.

Table I gives an account of the examinations made of milk, beer, bleaching
powder, proprietary disinfectants, etc. Though the number of samples analysed
continues to be very small, this part of Public Health work is bound to extend in
its scope in the near future.

(2) Examination and report on the Presidency water-supplies.
Table II shows the number of water samples examined at the Institute during
the year under report. Two new supplies were included in the programme of
routine periodical examinations of the year, viz., those of Rameswaram and of
Tuticorin.

Two half-yearly examinations were, as a rule, carried out from each supply,
the number of samples drawn being so adjusted as to include an examination of
the water before and after purification, and in the storage and distributory
systems. Such a detailed examination facilitated the detection and location of
defects which could be remedied by the authorities concerned and the result of the
remedy applied, could be estimated during the succeeding analysis.
Municipal water-supplies.— A detailed account of the sources from which the
municipalities, jails and railway stations draw their supply was given in the last
annual report and it is, therefore, sufficient in the present one, to record in a
general way the inferences that could be drawn from the results of the periodical
examinations of the water-supplies conducted during the year (vide appendix I).
Fourteen out of the 32 towns with protected supplies depend upon infiltration
galleries for their drinking water. Of these, Nellore, where the gallery is laid in
the bed of a river whose surface flow is practically non-existent, has been able to
maintain a uniformly good supply. Those municipalities whose galleries have
been laid in the beds of rivers subject to seasonal floods have yielded variable
results. At Madura, a new gallery on the banks of the river Vaigai at Kochadai

The Special Engineer of the Madras Corporation who has been planning out
experiments with a chlorination plant at Kilpauk suggested to the Committee that,
as a preliminary to those experiments, the sand filters at Guindy. may be worked
with layers of flat tiles and a reduced layer of sand at a very rapid rate with
a view to find out the extent of purification and improvement in physical appear-
ance effected thereby. Two sets of experiments were conducted and it was found
that, working at a very rapid rate, although the slow sand filter standard was not
reached, the water did improve in quality and in physical appearance to a slight
extent. Further experiments on these lines are now being conducted to get at
more definite conclusions.
The Filter Beds Committee have come to the conclusion that the time has
now come when, as a result of the experience gained from the working of the
Experimental Filters, it is desirable to set up an Inspectorate of trained men who
would visit the mufassal filters, carry out experiments and advise the executive on
the spot. They have accordingly formulated and sent up their recommendations
to Government on the subject and orders are being awaited.
I have great pleasure in placing on record the assistance given as usual, by
the Sanitary Engineer and his staff at the Guindy Experimental Filters where
the above work was conducted, and the loyal co-operation of the staff of the
Institute in carrying out such a large volume of work in all the sections.
