| Nutrient agar | 28,200 c.c. | ||
| Cholera bottles | 1,170 | ||
| MacConkey's broth | 61,980 c.c. | ||
| MacConkey's agar | 4,000 c.c. | ||

From the above table it will be seen that the media section carries
out heavy routine work. The washing and sterilising of all the glassware
used in the manufacture of cholera vaccine and other routine work is
also done by this section. The preparation of each brew of cholera
vaccine (Bulk Vaccine) entails the washing and sterilising of as many
as 300 pieces of glassware. The preparation of utensils for the filling
of diluted cholera vaccine is also a part of the duty of this section.
18. PLAGUE SECTION.—As in previous years, the Port Health Depart-
ment continued sending trapped and cyanogassed rats daily (excluding
holidays) from the port area. Dead and live rats were also sent to this
section from steamships. Every one of these rats was identified,
dissected and smears made from spleens were examined for the
presence of Pr. pestis. Examination proved negative in every case.
The following table shows the number of different species of rats
sent during the year under report:—
