  • 1. Zoonotic infections among cattle in urban and peri urban areas in Uganda -Brucella abortus bacteria in milk Kim Rock, DVM, MSc Presenter with input from Denis Rwabiita Mugizi, DVM, MSc Makerere University
  • 2. Uganda Why Gulu & Soroti? •Civil strife, now a post-conflict area •Little is known about disease status...
  • 3. Why brucellosis? • B. abortus is a bacteria that infects both animals & humans • Causes economic losses • Decreased milk production & abortions • Human infections from contact with infected animals or milk products • Cripples work force Control of brucellosis = Control of brucellosis in animals in humans
  • 4. Livestock ...are a source of livelihood to rural poor. • Meat • Milk • Dowry • School fees • Cash • Drought power
  • 5. Aim To improve food security in peri-urban regions of Gulu & Soroti, Uganda.
  • 6. Objectives of the studies • Is B. abortus present in Gulu & Soroti? – Determine the prevalence of antibodies against B. abortus in bulk milk – Identify the bacterium in milk via culture and PCR • What are the risk factors of brucellosis transmission in cattle? – Communicate, share & educate
  • 7. • Bulk Milk samples collected at: – 3 collecting centers – 6 boiling points – street vendors • Questionnaires to milk deliverers Methodology
  • 8. • Blood collected from 1007 cows from 166 herds • Milk collected from 207 cows • Herd level questionnaires
  • 9. Challenge = lack of milk Gulu- Nov 2011
  • 10. Results Gulu •142 milk samples •142 questionnaires Percent Prevalence = 11.7% •Intensive farming •Women farmers •Cattle are European mixes Soroti •188 milk samples •140 questionnaires Percent Prevalence = 35.3% •Extensive herds •Men farmers •More native breeds
  • 11. A. 69% in Gulu & Soroti answer, no. yes Q. Have heard of Brucella or brucellosis? 1 2 3 no yes no yes don’t know
  • 12. yes no no answer given no no A. 29% in Gulu & Soroti answer, yes. yes no Q. Do you take fresh milk?
  • 13. Risk factors of transmission established • Sharing of grazing grounds • Keeping a large herd •Outsourcing replacement stock •Keeping mixed breeds •Using hired animal attendants
  • 14. Present • Molecular typing & biotyping (PCR) of bacteria • Map milk value chain • Explore differences in brucella dynamics in Gulu & Soroti • Disseminate results along with Makerere University
  • 15. Take home message • Brucella is present and it is a real human & animal public health threat! • How can we best reduce Brucella’s threat to a safe and economically successful food supply? • Communication of new scientific knowledge to reduce human and animal infection. • Collaboration with Ugandan partners and researchers to encourage sustainability. • Exploration of other species’ roles in infection (sheep & goats.)
  • 16. Acknowledgments This study was supported by the Swedish Ministry of Foreign Affairs as part of its special allocation on global food security, UD 40. Makerere University
