A cross sectional study was undertaken from October 2010 to March 2011 to determine the seroprevalence of contagious bovine pleuropneumonia (CBPP) and its related risk factors in export quarantine centers. A total of 3,111 cattle sera were collected from different export quarantine farms located in and around Adama, namely, Bekero, Jogo, Kedir, and Dera farms, and tested for the presence of Mycoplasma mycoides subsp. mycoides small colonies antibody using competitive enzyme-linked immunosorbant assay. Of the total 3,111 cattle sera examined, 124 (4 %) were found positive for CBPP. Among the potential predisposing factors assessed, origin, transportation condition, confinement level, and stay time of the animals in quarantine center were not found significantly (P > 0.05) associated with the occurrence of the disease. Whereas age was found significantly (P < 0.05) associated with the occurrence of the disease in which a high seroprevalence was recorded in aged (9.5 %) animals than young (3 %). Generally, this study showed that CBPP is a threat for Ethiopian livestock export market and a well established disease in Borana and Bale areas, where the animals originated.
2010年10月至2011年3月开展了一项横断面研究，以确定出口检疫中心牛传染性胸膜肺炎（CBPP）的血清流行率及其相关风险因素。从位于阿达马及其周边地区的不同出口检疫农场，即贝克罗、乔戈、凯迪尔和德拉农场，共采集了3111份牛血清，并使用竞争酶联免疫吸附测定法检测了丝状支原体丝状亚种小菌落抗体的存在。在总共检测的3111份牛血清中，有124份（4%）被发现CBPP呈阳性。在评估的潜在诱发因素中，动物的来源、运输条件、圈养水平以及在检疫中心的停留时间与疾病的发生没有显著（P>0.05）关联。而年龄与疾病的发生有显著（P<0.05）关联，其中老龄动物（9.5%）的血清流行率高于幼龄动物（3%）。总体而言，本研究表明，CBPP对埃塞俄比亚的牲畜出口市场构成威胁，并且在动物来源地博拉纳和巴勒地区是一种常见疾病。
