A serological survey to determine the prevalence of contagious bovine pleuropneumonia (CBPP) in Mali was carried out by using the competitive enzyme linked-immunosorbent test (c-ELISA) on 8007 serum samples systematically collected from 199 cattle herds collected throughout the whole country. Results showed a national prevalence of 18.11 % at the individual level and 85.93 % at the herd level. Significant variations in the individual prevalence were observed between regions of the country and ranged from 4.63 % in Tombouctou to 54.88 % in Kidal. At the herd level, although there were variations between regions, a high prevalence was constantly observed ranging from 60 to 100 %, hence confirming the endemic nature of the disease across the country. The CBPP risk varied also between regions and was very low in Tombouctou (odds ratio (OR) = 0.4) but very high in Kidal (OR = 9.8). Similarly, the risk seemed higher in the animals of the over 3-year age group (OR = 1.6) compared to the other age groups. It was also observed that there was a slightly higher risk (OR = 1.3) in the females than in the males. This study confirms the presence of CBPP across the country and should help to elaborate strategies for the effective control of the disease.
为确定马里传染性牛胸膜肺炎（CBPP）的流行情况，采用竞争酶联免疫吸附试验（c-ELISA）对从全国199个牛群系统采集的8007份血清样本进行了血清学调查。结果显示，个体水平上全国流行率为18.11%，群体水平上为85.93%。该国不同地区的个体流行率存在显著差异，从通布图的4.63%到基达尔的54.88%不等。在群体水平上，尽管各地区存在差异，但始终观察到高流行率，范围在60%至100%之间，从而证实了该病在全国的地方性流行特征。CBPP风险在不同地区也有所不同，在通布图非常低（优势比（OR）=0.4），但在基达尔非常高（OR=9.8）。同样，与其他年龄组相比，3岁以上年龄组动物的风险似乎更高（OR=1.6）。还观察到，雌性动物的风险略高于雄性动物（OR=1.3）。本研究证实了CBPP在全国的存在，应有助于制定有效控制该病的策略。
