Pathology is the science dealing with the essential nature of disease; changes in the structure and function of tissues affected by the disease.
Pathological investigation of coral health and disease helps us answer:
- Which tissues are affected by this disease?
- What cellular changes are caused by the disease?
- Are there visible foreign organisms or potential pathogens present in the diseased tissue?
Pathological investigations are critical for determining the causal agents and precise impacts of disease. When combined with epizootiological data, this work can serve to accurately determine the threat of a disease to an affected population.
