A participatory epidemiological (PE) study was conducted in Kajo Keji and Yei Counties, Central
Equatoria State, southern Sudan to assess the impact of livestock diseases on livelihoods.
A serological survey of tick-borne diseases was conducted to supplement the PE study.
PE data collection tools consisted primarily of focus group interviews and key informant
interviews supplemented by observation. Information was collected on the social context,
history and species of livestock kept. Constraints in livestock keeping were explored
through description and probing. Proportional piling on the importance of different diseases
and relative incidence scoring were also conducted. 243 sera were collected from
cattle and tested for antibodies to Anaplasma marginale, Babesia bigemina, B. bovis, Theileria
mutans and T. parva by ELISA. Additionally, 173 blood samples were collected for a PCR
assay of T. parva. Livestock diseases were ranked as the most important constraint to livestock
keeping. While East Coast fever was ranked as the most important disease in Kajo
Keji, diarrhoea in small ruminants was reported as the most important disease in Yei. Serological
analyses of the sera indicated that A. marginale, B. bigemina, T. mutans and T. parva
were most prevalent. Prevalence of B. bovis was found to be low (4.0% and 7.4% in Kajo Keji
and Yei, respectively). 35% of the samples screened with the T. parva p104 gene nested PCR
assay were positive. The study concludes that while ECF is the most important disease in
Kajo Keji, it was not the case in Yei. Additional epidemiological studies are proposed before
control strategies are recommended
