Typhoid Fever—
32 samples of blood from suspected Typhoid cases have
been examined, and in 11 (i.e., 34.4 per cent.) the characteristic Widal reaction was obtained, although in all cases
but slightly marked. In 21 cases (i.e., 65.6 per cent.) no reaction was obtained. A high dilution of blood-serum is
used (1-60 to 1-100).
Diphtheria—
551 samples of throat and nose membranes and secretions
from doubtful diphtheria cases have been examined, and in
20 (i.e., 3.6 per cent.), the true (Klebs-Lœffler) bacilli have
been obtained. Of these 20 cases, 10 (i.e., 50 per cent.)
showed the Klebs-Loeffler bacilli in pure cultivation—i.e.,
without admixture with other bacilli, whereas in the remaining 10 (i.e., 50 per cent.) the Klebs-Lueffler bacilli were
found combined with staphylococci (6), pseudo bacilli (3),
and staphylococci and' streptococci (1).
In 531 (i.e., 96.4 per cent.) of the total number of throat
and nose samples examined, the Klebs-Lueffler bacilli were
not isolated, but other bacilli were found, e.g., staplylococci,
streptococci, torulœ micrococci, sarcinuœ, ana pseudo (Hoffmann) bacilli. The last-named was found in pure cultivation in 14 instances, mixed with staphylococci in 17, with
streptococci in 3, with staphylococci and streptococci in 2,
and' with staphylococci and sarcinœ in 1.
Other Examinations—
12 samples of other materials were examined, viz.: milk
6, hairs (tinea tonsurans) 4, cerebro-spinal fluid, 1, and urine
(pus) 1.
The samples of milk were sterilised and proved to be so,
by failing to show any lactic acid or butryic acid' fermentation after exposure to a temperature of 37 degrees C. for
lengthened periods.
