Castro Intestinal Infections:
The following notifications of this group of diseases were
received during the year.
Notified as Typhoid Fever:
One notification was received. The disease in this instance
was of long standing and the diagnosis was based entirely on
clinical findings as no pathogenic organisms were recovered
from the patient and his blood reaction was negative. His
employment necessitated his having meals in various parts of
London and no source of infection was traced.
Notified as Paratyphoid B.
4 notifications of this disease were received. The source
of infection was not ascertained in any of these cases but in
one instance the patient had returned from France within two
days of the onset of disease and it is assumed that he became
infected in that Country. In another case 3 other members of
the family were found to be carriers but none of these developed
any symptoms and their carrier state was eventually
cleared.
Notified as Dysentery:
14 notifications were received, 4 of the cases occurred in
one family but bacteriological investigation was negative. Of
the remaining cases bacteriological investigation was positive
in 3, the infecting organism concerned being sh sonnei in 2
eases and bact typhimurium in the other. In this last case the
patient ultimately died but he was an elderly man already
suffering from disease of the heart and blood vessels, and
this infection while contributory was not the primary cause
of death. In the remaining cases no bacteriological investigations
had been carried out, the patients having recovered
before the notifications were received.
Notified as Food Poisoning:
32 notifications were received. These can be grouped as
follows:—
8 in one household, bacteriological investigation, no
intestinal pathogenes isolated.
