Typhoid Fever—
39 samples of blood from suspected Typhoid cases have
been examined, and in 11 (i.e., 28.2 per cent.) the characteristic
Widal reaction was obtained, although in 10 of the cases
(i.e., 90.9 per cent.) the reaction was but slightly (or feebly)
marked. In 28 cases (i.e., 71.8 per cent.) no reaction was
obtained. A high dilution of blood-serum is used (1-60 to
1-100).
Diphtheria—
507 samples of throat and nose membranes and secretions
from doubtful diphtheria cases have been examined, and in
13 (i.e., 2.6 per cent.) the true (Klebs-Lœffler) bacilli have
been obtained. In 9 instances (i.e., 69.2 per cent. the KlebsLœffler
bacilli were obtained in pure cultivation—i.e., without
admixture with other bacilli, whereas in the remaining
4 (i.e., 30.8 per cent. the Klebs-Lœffler bacilli were found
combined with staphylococci.
In 494 (i.e., 97.4 per cent.) of the total number of throat
and nose samples examined, the Klebs-Lœffler bacilli were
not isolated, but other bacilli were found as follow:—
Staphylococci 225
Streptococci 87
Staphylococci + streptococci 40
Staphylococci + torulœ 13
Staphylococci + streptococci + torulœ 1

Torulœ 83
Steptococci + micrococci 2

Sarcinœ 2
Pseudo (Hoffmann) bacilli 13
