With anthrax bacilli vitality is retained for nearly a week; whereas, the comma bacillus appears to be killed in a very short time.
In gelatine cultures the comma bacilli can be cultivated for six weeks, and also in blood serum, milk, and potato, where anthrax bacilli rapidly form spores.
Spore formers such as anthrax can survive for an extended time, even under very adverse environmental conditions (dry, extremes of temperatures, and flooding).

Observations made on this property with respect to the anthrax bacillus at first gave the hope that it might explain variations in natural immunity.
This, for example, is the case with the anthrax bacillus; although the effect of this organism in the living body indicates the production of toxins which diffuse for a distance around the bacteria.
Both malignant œdema and symptomatic anthrax are similar in some respects toanthrax itself.
Koch disputed this, but more recently Bollinger has demonstrated the correctness of Pasteur's views by isolating anthrax contagium from five per cent.

Anthrax covers a wide geographical area all over the world, and no country seems altogether exempt.
From what has been said, it will be clear that anthrax carcasses are better not opened and exposed to free oxygen.
Thus, by means of the spores, the infection of anthrax may cling to the land for very long periods, even for years.
Its biological characters are shortly as follows: It is in thickness somewhat like the bacillus of symptomatic anthrax, thicker and shorter than the bacillus of malignant œdema, and standing therefore between the latter and anthrax itself.
Silk threads, impregnated with anthrax spores, were placed in bottles containing carbolic acid of various strengths, and at stated periods threads were removed and placed in nutrient media, and development or otherwise observed.
