This bacterium is susceptible to many antibiotics, yet only penicillin and oxytetracycline have the most effective under field conditions. The blood may fail to clot and can be found in the mouth, nostrils, and anus in the animals that die from anthrax. In severely infected cases, the animals are dead without premonitory clinical signs. The clinical courses of this disease in animals are peracute, acute, subacute, and chronic forms. Anthrax is enzootic in many Asian and African countries, and is reported in Australia, some parts of Europe, and America. Bacillus anthracis, the causative agent of anthrax, produces spores and persists for decades in the soil, initiating an outbreak through a favorable climate shift. In the farm animals, cattle and sheep are more susceptible, followed by goats and horses, while dwarf pigs and Algerian sheep are relatively resistant. Anthrax is a rapidly fatal infectious disease affecting herbivores and people.
