Contagious bovine pleuropneumonia (CBPP is a severe respiratory disease in cattle, caused by Mycoplasma mycoides subsp. mycoides. It poses a major threat to cattle health and livestock productivity. We aimed to pool CBPP prevalence estimates from different regions of Ethiopia, assessing implications for cattle management and productivity. The review followed PRISMA guidelines and searched PubMed, Web of Science, Scopus, HINARI, Google, and Google Scholar from January to February 2024. Funnel plots and Egger's regression tests were used to assess publication bias and small study effects. A pooled prevalence and 95 % confidence interval (CI) were calculated using R software. Twenty-three studies, covering 52,373 cattle, showed high heterogeneity (I² = 99 %, < 0.0001). The pooled CBPP prevalence in Ethiopia was 13 % (95 % CI: 7-21 %). Geographic differences, sampling methods, and cattle management practices influenced prevalence rates. There was no indication of publication bias (Egger's test, = 0.618). Prevalence was highest in the eastern (18 %), western (15 %), northern (14 %), and southern (4 %) regions. The prevalence was 16 % post-2016, compared to 8 % before 2016. Meta-regression showed that study location, herd size, body condition, and publication year significantly impacted CBPP prevalence. Small herds had 59 % lower CBPP risk, and animals in poor condition had 2.34 times higher odds of CBPP. The findings suggest a changing prevalence trend and emphasize the need to update CBPP prevention and control policies.
牛传染性胸膜肺炎（CBPP）是一种由丝状支原体丝状亚种引起的牛的严重呼吸道疾病。它对牛的健康和牲畜生产力构成重大威胁。我们旨在汇总埃塞俄比亚不同地区的CBPP患病率估计值，评估其对牛管理和生产力的影响。该综述遵循PRISMA指南，并于2024年1月至2月在PubMed、科学网、Scopus、HINARI、谷歌和谷歌学术上进行了检索。使用漏斗图和埃格回归检验来评估发表偏倚和小研究效应。使用R软件计算合并患病率和95%置信区间（CI）。23项研究涵盖了52373头牛，显示出高度异质性（I² = 99%，P < 0.0001）。埃塞俄比亚的合并CBPP患病率为13%（95%CI：7 - 21%）。地理差异、抽样方法和牛管理实践影响患病率。没有发表偏倚的迹象（埃格检验，P = 0.618）。患病率在东部地区最高（18%），其次是西部地区（15%）、北部地区（14%）和南部地区（4%）。2016年后的患病率为16%，而2016年前为8%。Meta回归显示，研究地点、畜群规模、身体状况和发表年份对CBPP患病率有显著影响。小畜群的CBPP风险降低59%，身体状况差的动物患CBPP的几率高出2.34倍。研究结果表明患病率趋势在变化，并强调需要更新CBPP的预防和控制政策。
