Seroprevalence and Risk Factors of Infection among Domestic Ruminants in East Hararghe Zone of Oromia Region, Ethiopia.

A cross-sectional study was carried out from July 2011 to September 2013 to assess the seroprevalence and identify risk factors of infection in domestic ruminants of East Hararghe zone of Oromia region, Ethiopia. Sera of 1360 domestic ruminants were analyzed for the presence of anti- IgG antibodies using the indirect enzyme-linked immunosorbent assay (iELISA). Additionally, the owners were also interviewed using a structured questionnaire to identify the potential risk factors of infection.

Mange mites of sheep and goats in selected sites of Eastern Amhara region, Ethiopia.

A cross sectional study of small ruminant mange mites was conducted from November 2011 to April 2012 on a total of 324 sheep and 680 goats, to determine the prevalence of mange mites in sheep and goats, identifying the major species of mite and to determine the potential risk factors significantly predicting the disease. The result showed an overall mange mite prevalence of 7.5 % (95 % CI 5.

Regulation of Oestrus ovis (Diptera: Oestridae) populations in previously exposed and naïve sheep.

Larvae of Oestrus ovis (Insecta: Diptera: Oestridae) are common parasites of nasal and sinus cavities of sheep and goats. During larval development, a specific immune reaction is initiated by the host with a humoral local and systemic response and the recruitment of eosinophils and mast cells in the upper airways mucosae. Nevertheless, the roles of these responses in the regulation of O.
