Zambezi fish disease

The Africa Science web log recently passed on a news story from SciDev.net about the disease that killed fish in parts of the Zambezi River last year. A team of scientists from the United Nations Food and Agriculture Organization (FAO), Thailand's Inland Aquatic Animal Health Research Institute, and the Network of Aquaculture Centres in the Asia-Pacific identified the disease as Epizootic Ulcerative Syndrome (EUS), caused by a fungal pathogen. Infected fish develop large sores and die from secondary infections. The post says researchers still don't know how the pathogen got into the Zambezi, which flows through eight southern African countries. In HOORC’s Library, you can read about fish pathology in the Ichthyology handbook by B.G. Kapoor and Bhavna Khanna.
