BACTERIUM SEPTICAMIA HEMORRHAGICH 81 
EXERCISE XXIX 
BACTERIUM SEPTICEMIA HEMORRHAGICA GROUP 
121. The name Bacillus septicemia hemorrhagice was given 
by Hiippe to the bacillus of swine plague (Smith). This bacte- 
rium (bacillus) is morphologically and in its cultural characters 
not distinguishable from the bacterium (bacillus) of rabbit 
septicemia (Koch), of fowl cholera (Pasteur), and of Schweine-, 
seuche (Schiitz). It is similar to a species of pathogenic bac- 
teria found more or less frequently in the upper air passages of 
nearly all of the domesticated animals. It is very similar also 
to a pathogenic bacillus found in broncho-pneumonia ‘in cattle 
and an infectious pneumonia in sheep. The diseases caused 
by these organisms are known as the Faszeurelloses, i.e. due to 
the organisms belonging to the genus Pas/eurella of Trevisan. 
122. Work for this exercise. Carefully examine and describe 
the cultures made in Exercise XXVIII. 
Examine the agar and bouillon cultures microscopically in both 
the living condition and in stained cover-glass preparations. 
Describe the appearance of the bacteria and make from one 
preparation a drawing of a few of them magnified 1000 diameters. 
Preserve a preparation to accompany notes. 
Measure a few of the bacteria with the filar micrometer and 
record the measurements. 
Make, stain, and examine a cover-glass preparation from an 
organ and the blood of a rabbit which has died from the inocu- 
lation with swine-plague bacteria (the rabbit will be furnished 
by the instructor). Stain the preparations with an aqueous 
solution of fuchsin. Study the bacteria in these preparations 
and carefully compare the two. 
Keep the cultures until the next exercise and examine them 
again, after which they may be rejected. 
Inoculate groups A and D of media with Bact. pullorum.
