PROPERTIES OF CULTURES OF ANTHRAX BACILLI GROWN AT VARIOUS TEMPERATURES
Abstract
The formation of spores was observed in a culture of anthrax bacilli at 43C. Therefore, the incubation of anthrax cultures at the stated temperature is not considered to be a completely satisfactory method for obtaining anthrax strains. By incubating a culture of anthrax bacilli in meat-peptone chicken broth with a pH = 7.1 - 7.2 at 45C, it was established that under these conditions they do not transform from the vegetative form into the spore form. During this the morphological, cultural and biochemical properties of the culture did not change. In a culture obtained following incubation of a virulent strain of the anthrax causative agent in broth at 45? for 7 days, a low virulence was combined with high immunizing properties -- after a single inoculation an intense immunity set-in in the animals.
