Tuberculosis Signs and Symptoms

A list of clinical signs the animal may or may not display.

Signs and symptoms of TB often are not apparent until the animal reaches advance stages of the disease.

TB lesions may be found in any organ or body cavity of diseased animals. In early stages of the disease, these lesions are difficult to find, even during post mortem examination. But in later stages, the nodules or lumps caused by bovine TB become very evident in the lungs and associated lymph nodes and in the lymph nodes of the head and intestinal tract. Lesions may also appear in the abdominal organs, reproductive organs, nervous system, superficial body lymph nodes, and bones.
