BookletWhat you need to know about epizootic ulcerative syndrome (EUS) – An extension brochure for Africa 2020
Also available in:
No results found.This extension brochure – What you need to know about epizootic ulcerative syndrome (EUS) – provides simple facts or answers to frequently asked questions about EUS. This brochure is intended to address a wide range of audiences 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 a better understanding of its potential impact. -
Book (stand-alone)Report 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. -
Brochure, flyer, fact-sheetWhat you need to know about Tropical Race 4
TR4 Global Network - An initiative of the World Banana Forum
2020The flyer, What you need to know about TR4, aims to inform the general public with basic information about Tropical race 4 (TR4). The underlying message is that actions can indeed be taken to help prevent the spread of the pest and that the way forward is for stakeholders across the banana industry to act with urgency and in a collaborative manner. Fusarium Tropical race 4 (TR4) is a strain of the soil born fungus, Fusarium oxysporum f. sp cubense whose spores can lie dormant in the soil until a susceptible plant is established nearby. These spores infect the plant through the roots and inhabit the banana or plantain plant’s xylem vessels, blocking the flow of water and nutrients. Fungicides can't save plants that are already infected with TR4, and the fungus's spores persist in soil for decades. Therefore the most immediate approach to combat TR4 is prevention of its spread into clean areas and containment when it is detected. In the long term, diversification of crops and better use of available genetic resources are key to building resilience to the disease. Agro-ecological innovations will be increasingly important to produce varieties less susceptible to TR4. The flyer focuses on three practical items that a visitor to a banana or plantation farm can do to minimise the risk of spreading TR4.
