Der er foretaget studier ved eksperimentelle infektioner hos dyr efter inhalation af Bacillus anthracis sporer; disse studier viser, at tidlig antibiotikabehandling efter eksponering, kan forhindre sygdommen, hvis behandlingen tilpasses til at mindske antallet af sporer i organismen med den infektive dosis.
Studies have been conducted in experimental animal infections due to inhalations of Bacillus anthracis spores; these studies reveal that antibiotics starting early after exposition avoid the occurrence of the disease if the treatment is made up to the decrease of the number of spores in the organism under the infective dose.
