Summary of the Thesis

This study aimed to assess the knowledge of brucellosis among pastoralists; to estimate its prevalence; to determine its association to abortions and to identify Brucella species prevalent in humans and domestic ruminants in the Kagera region. A cross-sectional survey and a prospective cohort were conducted (using qualitative, serological and molecular tools) in Karagwe and Ngara districts. Findings indicated low knowledge of brucellosis by pastoralists of Kagera where Brucella spp. are circulating endemically (7.7%, 6%, 2.5% and 0.5% in humans, cattle, goats and sheep, respectively). By Sanger sequencing Brucella spp.were phylogenetically grouped in two clades closer to B. melitensis, B. abortus and B. suis. This raises the suspicion of the contribution of brucellosis to reproductive failures in Kagera ecosystem of Tanzania.
