    Participatotory Apprisal and Seroprevalence Study of Foot and Mouth Disease in Borana Pastoral System South Ethiopia
    (Addis Ababa University Faculty Of Veterinary Medicine, 2006) Rufael, Tesfaye; Ass.Prof Boga, Asscged
    Participatory appraisal and conventional veterinary investigation methods were applied to \alidate Barana pastoralists' knowledge on cattle disease and to investigate the epidemiology of Foot and Mouth disease ( Ft\lD), respe-ctivcly in Barana pastoral production system of Southern Ethiopia. Furthennore, detcnnin3ti oll of seroprevalencc of FMD and assessment of associated risk factors (including serotyping of the c irculating FMD vims) were conducted. The participatory methods used were clinical observation. matrix scoring, proportional piling. and seasonal calendars. Seroepldcmiological investigations were perfomlcd using JABC ELISA a nd liquid phase blocking ELISA techniques. The analysIs of matrix sconng showed good level of agreement (\\"- 0.569·0.956) among {he 12 mfomlant groups for the disease indicators.
