doubt that pseudo-throats form a suitable breeding ground
upon which true Diphtheria bacilli may, at any time, become
engrafted and spread rapidly, whilst it may even be that,
at times, the pseudo-bacilli change into the true KlebsLoeffier
bacilli, or vice-versa. This being the case, it is
safest to regard these pseudo-throats as infectious, and to
have the patients isolated—a view that is now taken by the
Education Department of the London County Council.
In connection with the 3,188 examinations made of throat
and nose membranes and discharges, full particulars were
noted of the different bacilli found and cultivated. The
Klebs-Loeffler bacillus was found in pure cultivation in 251
(i.e., 58 per cent.), and combined with other well-known
bacilli as follows:-
Klebs-Loeffler + Streptococci 60
Klebs-Loeffler + Staphylococci 64
Klebs-Loeffler + Staphylococci + Streptococci 23
Klebs-Loeffler + others 17
Klebs-Loeffler + Pseudo-bacilli 2
Klebs-Loeffler + Pseudo + others 13
Klebs-Loeffler + Vincent's organisms 3
In connection with the 2,755 cases in which the KlebsLoeffler
Diphtheria bacilli were not isolated, other bacilli
were found as follows:-
Streptococci (pure cultivation) 220
Streptococci + others 30
Staphylococci (pure cultivation) 1099
Staphylococci + others 136
Streptococci + Staphylococci 566
Streptococci + Staphylococci + others 118
Pseudo-bacilli (Hoffman), pure cultivation 60
Pseudo-bacilli (Hoffman) + Staphylococci 271
Pseudo-bacilli (Hoffman) + Streptococci 75
Pseudo-bacilli (Hoffman) + Staphylococci +
Streptococci 76
Pseudo-bacilli + others 83
Smegma (pure cultivation) 3
Smegma + others 3
Diplococci (pure cultivation) 1
Micrococci (pure cultivation) 7
Torulœ (pure cultivation) 3
Torulœ + Micrococci 2
Vincent's organisms 2
