BrochureWhat you need to know about epizootic ulcerative syndrome (EUS) - An extension brochure 2009
Also available in:
This extension brochure – What you need to know about epizootic ulcerative syndrome (EUS) – provides simple facts or frequently asked questions about EUS. This brochure is intended to a wide range of audience from fish farmers and fishermen to extension officers as well as policy-makers as a public information campaign to make available factual information about the disease so that awareness may be raised for better understanding of its potential impact.This brochure, an outcome of FAO’s Techni cal Cooperation Project TCP/RAF/3111 Emergency Assistance to Combat Epizootic Ulcerative Syndrome in the Chobe/Zambezi River System, was prepared under the technical supervision of Dr Melba B. Reantaso and Dr Rohana P. Subasinghe of the Aquaculture Management and Conservation Service, Fisheries and Aquaculture Management Division, FAO Fisheries and Aquaculture Department. -
FactsheetEnhancing Capacity to Respond and Manage the Risk of Epizootic Ulcerative Syndrome (EUS) in Malawi - TCP/MLW/3804 2025

No results found.The project focused on safeguarding the ecosystems of the Bua River and Lake Malawi, which host various fish species, including the endangered Opsaridium microlepis. By controlling the spread of EUS, the project helped preserve the health and genetic diversity of wild fish populations, crucial for the sustainability of Malawi’s aquatic resources. The project also had a significant economic impact, benefiting over 1.6 million people who depended on the fisheries sector for their livelihoods. This included not only fishers but also individuals involved in fish processing, marketing, and related activities. By managing the outbreak, the project mitigated potential income losses caused by fish stock declines, ensuring that rural communities, particularly those near lakes, maintained viable economic opportunities. -
Technical reportReport of the International Emergency Fish Disease Investigation Mission on a Suspected Outbreak of Epizootic Ulcerative Syndrome (EUS) in the Democratic Republic of Congo, 13-19 March 2015 2017

No results found.In response to a request for an emergency technical assistance from the Government of the Democratic Republic of Congo (DRC) in connection with a serious disease affecting fish in Lokame River in Loko and in Mbanza Oton, 60 km from Gbadolite, FAO formed an International Emergency Disease Investigation Task Force. The overall objective of the Task Force was to (1) confirm that an outbreak was happening; establish a case definition and presumptive diagnosis of the causative agent; (2) collect and process fish samples for relevant laboratory tests; (3) identify risk factors, confirm diagnosis and define further investigation or follow-up work; (4) recommend border/cross border control measures to prevent further spread of the disease; (5) identify specific short-term and medium-term biosecurity action plans that the government may undertake; and (6) provide further recommendations to FAO on how to prevent the further spread of the disease. Some members of the Task Force travelled to DRC from 13 to 19 March 2015, conducted field investigations and laboratory test and has confirmed the presence of the epizootic ulcerative syndrome (EUS) using three recommended confirmatory tests such as: (i) demonstration of mycotic granulomas and fungal structures in stained histological sections, (ii) isolation of Aphanomyces invadans on culture media and (iii) positive identification by polymerase chain reaction (PCR) of A. invadans genomic DNA. The Task Force concluded that permissive facto rs that favoured the propagation, infectivity and disease occurrence of EUS occur in the rivers and streams investigated in the Equateur Province of DRC. The findings also showed that environmental, climatic, water quality and human demographic conditions in the Congo River basin support the possibility of pandemic spread of the disease. The Task Force suggested several actions which need to be undertaken to curb the spread of the outbreak. These include active surveillance and monitoring of fi sh markets and other food channels used in the movement of live fish, capacity building for involved government personnel to strengthen knowledge and expertise in the identification and control of the disease through biosecurity measures, continued dialogue among DRC, neighbouring countries and FAO about EUS status including subregional disease surveillance, monitoring, and response programmes, and the formulation of a national aquatic biosecurity strategy for DRC.
