made from the organs. The organism was fatal to experimental 
animals and to calves. It was more virulent than the bacillus of hog 
cholera obtained from hogs dead of that disease. 
Since Gertner first discovered this organism in 1888 in the meat of 
a diseased cow, it has been isolated by others from both animals and 
man. It has been found to be pathogenic for animals, and several 
people have been reported to have become ill from eating broth made 
from meat containing this organism. During the last few years 
several bacilli differing slightly from Geertner’s bacillus have been 
isolated from cases of meat poisoning. 
Bacilli of this group, or at Jeast of closely related groups, have fre- 
quently been found to stand in a causal relation to the lesions with 
which they were associated. The more important of these are 
Bacillus typhi murium obtained by Loeffler in 1890 from an enzodtic 
among mice, the bacillus isolated by Mereshkowsky in 1895 from the 
ground squirrel, and Bacillus psittacosis isolated by Nocard in 1893 
from the organs of parrots. 
Bacteria. belonging to the “Intermediate group” (Gertner and colon 
bacilli) have been isolated from diseases in ground squirrels, field 
mice, ferrets, pigeons, parrots, yellow fever in man, septicemia in 
calves and still other morbid conditions.
