A lethal infection is reported to result from inhalation of about 10,000–20,000 spores, though this dose varies among host species.Little documented evidence is available to verify the exact or average number of spores needed for infection.Anthrax can enter the human body through the intestines (ingestion), lungs (inhalation), or skin (cutaneous) and causes distinct clinical symptoms based on its site of entry. However, anthrax does not usually spread from an infected human to a noninfected human.But, if the disease is fatal to the person's body, its mass of anthrax bacilli becomes a potential source of infection to others and special precautions should be used to prevent further contamination.Herbivores are often infected whilst grazing, especially when eating rough, irritant, or spiky vegetation; the vegetation has been hypothesized to cause wounds within the gastrointestinal tract permitting entry of the bacterial endospores into the tissues, though this has not been proven.Once ingested or placed in an open wound, the bacteria begin multiplying inside the animal or human and typically kill the host within a few days or weeks.Occupational exposure to infected animals or their products (such as skin, wool, and meat) is the usual pathway of exposure for humans.Workers who are exposed to dead animals and animal products are at the highest risk, especially in countries where anthrax is more common.

Today, this form of infection is extremely rare in advanced nations, as almost no infected animals remain.

These toxins are the primary agents of tissue destruction, bleeding, and death of the host.

If antibiotics are administered too late, even if the antibiotics eradicate the bacteria, some hosts still die of toxemia because the toxins produced by the bacilli remain in their system at lethal dose levels.

However, anthrax vegetative bacteria that escape the body via oozing blood or through the opening of the carcass may form hardy spores. Once formed, these spores are very hard to eradicate.

The infection of herbivores (and occasionally humans) by the inhalational route normally proceeds as follows: Once the spores are inhaled, they are transported through the air passages into the tiny air sacs (alveoli) in the lungs.

Nearby lymph nodes may become infected, reddened, swollen, and painful. Cutaneous anthrax is rarely fatal if treated, because the infection area is limited to the skin, preventing the lethal factor, edema factor, and protective antigen from entering and destroying a vital organ.
