FMD In Uganda • Endemic • Serotypes O, A, C , SAT 1, 2 and 3 • Cattle and African buffalo (SAT 3) • Scanty information on FMD situation in goats and sheep • Outbreaks OBJECTIVES OF THE STUDY
• Sero-prevalence of FMD in small ruminants and the serotypes involved
• Determine if any difference exists in the prevalence rates under the different farming practises MATERIALS AND METHODS

1. Although ignored in FMD control strategies, goats and sheep are sero-positive for FMD in Uganda
2. Serotypes identified are type O, SAT 1, 2 and 3
3. Husbandry practises may affect FMD sero- prevalence in FMD endemic situation
