Typhoid Fever—
48 samples of blood from suspected Typhoid Fever cases
have been examined, and in 12 (i.e., 25 per cent.) the characteristic
Widal reaction was obtained, although in 10 of the cases
(i.e., 83.3 per cent.) the reaction was but slightly (or feebly)
marked. In 36 cases (i.e., 75 per cent.) no reaction was
obtained. A high dilution of blood-serum is used (1-60 to
1-100).
Diphtheria—
538 samples of throat and nose membranes and secretions
from doubtful diphtheria cases have been examined, and in 26
(i.e., 4'8 per cent.) the true (Klebs-Lceffler) bacilli have been
obtained. In 21 instances (i.e., 80'8 per cent.) the KlebsLceffler
bacilli were obtained in pure cultivation—i.e., without
admixture with other bacilli, whereas in the remaining 5 (i.e.,
19.2 per cent.) the Klebs-Lœffler bacilli were found combined
with other well-known bacilli as follows:—
Klebs-Lceffler bacilli + staphylococci 3
Klebs-Lceffler bacilli + pseudo (Hoffmann) bacilli +
staphylococci 1
Klebs-Lceffler bacilli + pseudo (Hoffmann) bacilli +
streptococci 1
