Typhoid Fever—
55 samples of blood from suspected Typhoid Fever cases;
have been examined, and in 15 (i.e., 27.3 per cent.) the characteristic
Widal reaction was obtained, although in 5 of the cases
(i.e., 33.3 per cent.) the reaction was but slightly (or feebly)
marked. In 40 cases (i.e., 72.7 per cent.) no reaction was
obtained. A high dilution of blood-serum is used (1-60 to
1-100).
Diphtheria—
431 samples of throat and nose membranes and secretions
from doubtful diphtheria cases have been examined, and in 33
(i.e., 7.7 per cent.) the true (Klebs-Lœffler) bacilli have been
obtained. In 23 instances (i.e., 69.7 per cent.) the KlebsLoeffler
bacilli were obtained in pure cultivation—i.e., without
admixture with other bacilli, whereas in the remaining 10 (i.e.,
30.3 per cent.) the Klebs-Lceffler bacilli were found combined
with other well-known bacilli as follows:—
Klebs-Lceffler bacilli + staphylococci 6
Klebs-Lceffler bacilli + staphylococci + torulœ 2
Klebs-Lceffler bacilli pseudo (Hoffmann) bacilli 1
Klebs-Loeffler bacilli + pseudo (Hoffmann) bacilli +
torulce + micrococci 1
In 398 (i.e., 92.3 per cent.) of the total number of throat and
nose samples examined, the Klebs-Loeffler bacilli were not
isolated, but other bacilli were found as follow:—
Staphylococci 264
Streptococci 52
Staphylococci + streptococci 34
Staphylococci + sarcinœ l
Staphylococci + torulœ 16
Staphylococci + micrococci 3
