Animal and Zoonotic diseases. Overall development objective to contribute to alleviation of food insecurity and poverty by increasing animal productivity and public health
E N D
Animal and Zoonotic diseases • Overall development objective to contribute to alleviation of food insecurity and poverty by increasing animal productivity and public health • Overall academic objective is to contribute to the increased capacity building in the field of veterinary medicine, animal nutrition and human parasitology.
Animal and Zoonotic diseases Research topics • The epidemiology and control of helminth infections • The epidemiology and control of trypanosomosis • The importance and epidemiology of zoonotic diseases • The epidemiology and control of mastitis • Nutritive value of locally available feeds for livestock
Animal and Zoonotic diseases New collaborative approach • To adapt better to the local capacity and capability of the Veterinary School e.g. experience in research, laboratory techniques, organisational expertise (samplings etc), availability of laboratory equipment • To improve collaboration between researchers and research groups and increase the number of scientists involved in the project • To exploit research opportunities relevant to the region and the whole country including urbanisation, increased demand for milk and milk products and encroachment of livestock into fertile tsetse-infested areas
Animal and Zoonotic diseases 3 research themes
Zoonotic component Objectives • To understand the importance and epidemiology of zoonotic diseases, in particular taeniasis/cysticercosis and echinococcosis/hydatidosis Activities first working year • Abattoir-based study on Taenia saginata and Echinococcus granulosus in cattle between Oct 2007 -Mar 2008 • Training of Ethiopian topic leader at ITMA in serological techniques Results • 512 carcasses inspected, samples taken for parasitological and serological examination • 15 (2.93%) infected with T. saginata metacestodes, and 161 (31.44%) with hydatid cysts Future work • Continue work on Echinococcosis: genotyping, zoonotic importance, prevalence in dogs
Urban component: Mastitis • Objectives • 1) To determine the bacterial flora involved in mastitis • 2) To determine the clinical importante of mastitis in the Jimma zone • 3) To assess the quality and usage of the available mastitis treatment • 4) To suggest contol measures for mastitis • Activities • Activity 3.1: Specific areas where the surveys will be conducted will be identified • Activity 3.2: The prevalence of mastitis and bacteria involved will be studied • Activity 3.3:The currently applied mastitis prevention measures will be evaluated • Activity 3.4: Recommendations to control mastitiswill be developped
Rural component: Helminth diseases Objectives • To understand the basic epidemiology of helminth infections in cattle in the Jimma zone Activities • Training of topic leader at UGent on basic parasitological techniques • Visits to villages to identify where longitudinal studies could be initiated to determine prevalence and seasonal variations of helminth infections Results • Study areas around Jimma identified • Faecal samples collected and examined: 47% of animals infected with gastro-intestinal parasites and/or liver fluke Future work • Longitudinal studies in selected areas • Study importance of parasitic infections in rural and urban areas
Animal and Zoonotic diseases Rural component: Livestock trypanosomiasis • Objectives • 1. To collect baseline data on the prevalence and impact of trypanosomal infections in livestock in the various study sites with different trypanosomosis control history • 2. To isolate trypanosome strains from cattle in the various study sites in the Jimma region and determine their level of resistance (trypanocidal drug reference centre) • 3. To conduct a questionnaire survey to evaluate the ongoing trypanocidal drug use practices in the various study sites in the Jimma region • 4. Develop appropriate trypanosomosis control strategies • Activities • Activity 2.1. Collect baseline data • Activity 2.2. Identify study sites (3), based on epidemiological setting • Activity 2.3. Determine prevalence and impact of trypanosomal infections • Activity 2.4. Isolate trypanosome strains from cattle and determine susceptiblity • Activity 2.5. Conduct drug use survey • Activity 2.6. Analyse survey data and develop control strategies
Project 1: Zoonotic and Animal Diseases Animal Nutrition Team Belay DUGUMAYisehak KECHEROGeert JANSSENS IUC-JU North meeting, Oct. 8, 2008
Main topics • Rural component: Development of sustainable livestock feeding around the Gilgel Gibe dam • Urban component: Optimising urban dairy cow nutrition
Livestock feeding around the dam • Local perception of problems and identification of bottlenecks in view of seasonality • Questionnaire: 330 household in 5 distinct regions • Bio-mass estimations of feed resources • Determination of nutritional value of feed resources • Chemical analysis • Digestibility tests with local breeds • Evaluating in-the-field indicators of herd nutritional status • Faecal nitrogen fractions • Micromineral ratios • Saponins • Adjust the identified first limiting nutrients • Optimise existing rations through formulation • Promote production of specific crops that adjust nutrient deficiencies in a sustainable way regarding ecology and economy (to be further developed by multidisciplinary approach increase cooperation with other teams)
Optimising urban dairy nutrition • Identify most important deficiencies • Questionnaire on feeding practices and animal performance • Analyse total rations for nutritional value and compare with nutrient requirements • Identify practical means to adjust deficiencies • Optimise use of by-products • Introduce new feed resources • Ration formulation • Improve rations to increase milk production and disease resistance • Measure milk production and its main composition • Measure inflammatory and mastitis parameters • Improve rations to increase nutritional quality of the milk (for infants increase collaboration with Project 2) • Microminerals (Zn, Cu, Se, …) • Fatty acid profile
Problems • A major overall problem is the purchase of equipment. After one year the material ordered in Belgium has not yet arrived in Jimma. • Limited laboratory capability • Current research is mainly person-oriented (PhD projects) • Limited knowledge of the relevance of veterinary and zoonotic diseases and/or limited exploitation of available information (e.g. MSc and DVM theses) • Current research focus is descriptive rather than analytical • Irregular feed-back on research progress • Availability of transport for work in urban areas • For non-PhD students, the available time that can devoted to the research projects is limited • Recommendations • It should be better explored what material can be purchased locally (Jimma & especially Addis Ababa • To increase the number of Belgian scientists/technicians supporting the establishment and activities of the laboratories at the Veterinary School • To complete construction work at the Veterinary School so that a parasitological laboratory can be established in the new building • Establish team-oriented research approach • Meta-analysis of available studies performed in the region and determine relevant research priorities • To establish a reporting format and schedule and organise an annual scientific (progress) meeting between Belgian and Ethiopian researchers • To purchase two motorbikes (locally) to support activities of the urban component of the project • The Jimma University policy should allow non-registered students to devote time to the research projects of the Veterinary Project of the IUC • To organise a meeting between Belgian collaborators of the veterinary project and between Belgian scientists of the various IUC projects to brief on project activities and exchange ideas
