Anthrax Diagnosis. The causal bacterium Bacillus anthracis rapidly produces spores when exposed to air. et Microbiol. Sudden death in an animal without prior signs should lead to a suspicion of anthrax. Anthrax can affect a wide variety of domestic and wild animals, and humans. If anthrax is suspected as the cause of death, the carcass should NOT be opened because exposure of the vegetative anthrax bacteria in body fluids to oxygen induces spore formation. However, because of its rarity, it is not often included in the differential diagnosis and in inhalational disease the diagnosis is rarely made until the patient is moribund. Anthrax most commonly occurs in the New South Wales 'anthrax belt' from Moree and Walgett down to the Victorian border from Corowa to Deniliquin. Dogs and cats are generally resistant to anthrax.

It usually only affects farm animals like cows and sheep. Birds usually are naturally resistant to anthrax. Situations may also occur where anthrax is considered as a differential diagnosis during the course of a routine investigation into livestock deaths. Samples must be collected carefully to avoid contamination of the environment and to prevent human exposure to the bacteria. Infections in people are caused by contact with the spores through a cut or scratch in the skin (known as cutaneous anthrax), by inhaling the spores (known as inhaled or pulmonary anthrax), or by eating meat that contains the spores (known as intestinal anthrax). Anthrax is most common in wild and domestic herbivores (eg, cattle, sheep, goats, camels, antelopes) but can also be seen in people exposed to tissue from infected animals, to contaminated animal products, or directly to B anthracis spores under certain conditions. Exposed animals may need to be treated with antibiotics, while dead animals need to be disposed of promptly on-site. Hot and dry conditions are perfect for the development of anthrax.
