Dogs are rarely affected, but develop a similar disease to that found in pigs. Disease most often occurs due to scavenging of infected carcasses. Clinical signs include severe inflammation and oedema of the pharyngeal region and the disease is usually not fatal.

===Diagnosis===

===Diagnosis===

In most affected animals (pigs being an exception), large numbers of B. anthracis are found in the blood. A sample from a fresh carcass may be collected from an incision made in a well vascularised area such as the ear. In pigs, a small piece of lymphatic tissue should be collected aseptically and submitted. Diagnostic tests include bacterial culture, PCR and fluorescent antibody stains for demonstration of the bacillus in blood or tissue.

===Pathology===

Bloody discharges from body orifices may be observed in carcasses. Rigor mortis is often absent or incomplete in dead animals.  Failure of the blood to clot and splenomegaly are other important post mortem findings.

Rigor mortis is often absent or incomplete in dead animals.  Failure of the blood to clot and splenomegaly are other important post mortem findings. Lymph nodes are often swollen and oedematous. Haemorrhages may be found on the serosal surfaces of the thorax and abdomen as well as the endocardium.
