Abstract

A cross sectional study was carried on bovine brucellosis from November 2008 to March 2009 to determine the sero-prevalence and distribution of bovine brucel osis in selected sites of Jimma zone, Southwestern Ethiopia. A total of 950 animals (541 female and 409 male) were examined serologically by using RBPT as screening test and CFT as confirmatory test. Out of the total animals tested 26 (2.74 %) were found positives reactors for brucella antibody by RBPT and this was further tested by CFT in which 10 (1.1%) animals were found positive reactors for brucella antibodies. Significant variation were observed among woredas with seropositivity of the animals (p 0.05). In addition, no significance dif erence observed among pregnancy, lactation and parity status (p>0.05) with seropositivity to the disease. Key Words: Bovine brucel osis, CFT, RBPT, Risk Factors, Seroprevalence De novembre 2008 a mars 2009 une etude transversale sur la brucellose bovine a ete menee pour determiner la prevalence serologique et la repartition de la brucellose bovine dans des sites selectionnes de la region de Jimma au sud-ouest de l’Ethiopie. Un total de 950 animaux (541 femel es et 409 mâles) a ete soumis au test serologique par l’utilisation de RBPT (epreuve d’agglutination sur plaque a l’antigene tamponne) comme test de depistage et CFT (reaction de fixation du complement) comme test de confirmation.

牛布鲁氏菌病与流产血清患病率及相关危险因素的研究。
2008年11月至2009年3月对牛布鲁氏菌病进行了横断面研究,以确定埃塞俄比亚西南部吉马地区选定地点牛布鲁氏菌病的血清流行率和分布。以RBPT为筛选试验,CFT为确认试验,对950只动物(雌性541只,雄性409只)进行血清学检查。在全部测试动物中,26只(2.74%)被RBPT发现布鲁氏菌抗体阳性反应,CFT进一步测试了这一点,其中10只(1.1%)动物被发现布鲁氏菌抗体阳性反应。血清阳性动物的不同工种间差异有统计学意义(p < 0.05)。此外,妊娠、哺乳期和胎次状况与疾病血清阳性无显著性差异(p < 0.05)。关键词:牛布鲁氏菌病,CFT, RBPT,危险因素,血清患病率2008年11月至2009年6月,在埃塞俄比亚西南部吉马地区进行的一项研究中,测定了布鲁氏菌病的流行情况,血清学和重新划分了布鲁氏菌病的位点选择。总共有950只动物(541只雌性动物和409只雄性动物)进行了血清学测试,包括RBPT(血小板凝集和抗原棉膜)、dedepistage测试和CFT(补体反应固定测试)和deconfirm测试。结果显示,共有26例(2.27%)动物检测结果呈阳性,其中10例(1.1%)动物检测结果呈阳性,其中1例(2.27%)动物检测结果呈阳性,1例(2.27%)动物检测结果呈阳性,1例(2.27%)动物检测结果呈阳性。两组之间的重要差异在于小鼠血清免疫阳性(p < 0.05)。此外,在妊娠期、哺乳期、分娩期和妊娠期血清阳性率方面,两组间差异均有统计学意义(p < 0.05)。类别:布鲁氏菌,CFT, RBPT,风险因素,血清患病率
