under certain conditions. The combined method (serum per 
rectum and intramuscular injection) has given just as good 
results as any method of administering the serum, and is safer

Finally, the serum acts in a specific manner, but at the same 
time it may act as a foreign protein, producing nonspecific an- 
tibodies. Above all it must be given early, even in cases where 
bacillary dysentery is only suspected, in order to produce good 
results.
