    Factors associated with persistence of African animal trypanosomiasis in Lango subregion, northern Uganda
    (Tropical animal health and production, 2019-04) Wangoola, Robert Mandela; Bardosh, Kevin; Acup, Christine Among; Susan, Welburn; Waiswa, Charles; James, Bugeza
    African animal trypanosomiasis (AAT) continues to inflict heavy losses on livestock production especially cattle in terms of decreased production and productivity in Uganda. AAT is a disease complex caused by tsetse fly-transmitted Trypanosoma brucei brucei, Trypanosoma brucei rhodesiense, Trypanosoma congolense, and Trypanosoma vivax. The disease is most important in cattle but also known to cause serious losses in pigs, camels, goats, and sheep. Several control measures including live bait technology, mass treatment of cattle with trypanocidal drugs, and deployment of tsetse traps have been used in the past 10 years, but the problem still persists in some areas. This necessitated an exploration of the factors associated with continue trypanosome infections in cattle, which are also known reservoirs for the zoonotic trypanosomiasis. A structured questionnaire was administered to 286 animal owners from 20 villages purposively selected from Lira, Kole, and Alebtong districts of Lango subregion to obtain information on the factors associated with persistence of infection. Over 50% of the respondents reported trypanosomiasis as a major challenge to their livestock. Land ownership (P = 0.029), type of livestock kept (P = 0.000), disease control strategy employed (P = 0.000), source of drugs (P=0.046), and drug preparation (P=0.017) were associated with persistent AAT infection. We recommend continued farmer sensitization on the threat of AAT and the available prevention and control options. The use of isometamidium chloride for prophylaxis against trypanosomiasis is highly recommended. There is also a need to foster qualified private veterinary drug supply in the region.

    Sero-prevalence and Risk Factors Associated with Bovine Brucellosis in Central Equatoria State, South Sudan
    (Scholars Journal of Agriculture and Veterinary Sciences, 2016) Emmanuel, P. Lita; Nasinyama, George W.; Ochi, Erneo B.; James, Bugeza; Erume, Joseph
    Brucellosis is one of the most important zoonotic diseases of livestock and human in South Sudan. A crosssectional study was conducted in peri-urban Juba town and rural Terekeka County to estimate sero-prevalence and determine risk factors of bovine brucellosis. Ninety (90) respondents were randomly interviewed on demographic information and potential risk factors to brucellosis. Out of the 90 respondents interviewed, 44 were from 44 cattle herds in peri-urban Juba and 46 from 46 cattle herds in rural Terekeka County. Sera of 502 cattle were screened for Brucella antibodies using Rose Bengal Plate test. The positive sera on RBPT were then confirmed by competitive Enzyme-linked Immunosorbent Assay. SPSS version-18 and frequencies were used for sero-prevalence. Chi square and binomial logistic regressions were used for analysis of risk factors. RBPT and c-ELISA tests showed positive reactors and an overall individual animal sero-prevalence of 23.2%, 95% confidence interval (CI): (18.4 - 28.8) and 19.2%, 95% CI: (2.5 – 14.0), respectively in peri-urban Juba town. However, in rural Terekeka County the respective results showed seroprevalence of 40.5%, 95% CI: (34.5 – 46.4) and 39.3%, 95% CI: (33.3– 45.2). The overall herd level sero-prevalence on c-ELISA revealed 61.4% and 90.0% for peri-urban Juba town and rural Terekeka County cattle herds, respectively. The individual animal level risk factors in the study area revealed abortion history (OR= 4.941 and (CI): 2.077-11.753) and (OR= 6.251 and (CI): 2.920-13.379) significantly associated with brucella sero-positivity, respectively. No risk factor determined at herd level in peri-urban Juba town. However, in rural Terekeka County herds, number of cattle above 300 in a herd (p= 0.005, OR= 44.934) was significantly associated with brucellosis sero-positivity. Further epidemiological studies are needed for developing appropriate control strategies against bovine brucellosis in South Sudan.
