The Gram-negative bacteria of the genus cause a wide range of diseases in humans and animals. The seroprevalence of in domestic black-boned sheep and goats in China is unknown. In this survey, a total of 481 serum samples were collected randomly from domestic black-boned sheep and goats from three counties in Yunnan province, southwest China, from July to August 2017. The sera were examined by an indirect hemagglutination assay (IHA). Antibodies to were detected in 100/481 [20.79%, 95% confidence interval (CI), 17.16-24.42] serum samples (IHA titer ≥1:64). The seroprevalence ranged from 12.21% (95% CI, 7.81-16.61) to 30.89% (95% CI, 22.72-39.06) across different regions in Yunnan province, and the differences were statistically significant ( < 0.01). The seroprevalence in male domestic black-boned sheep and goats (28.64%; 95% CI, 22.36-34.92) was significantly higher than that in the females (15.25%; 95% CI, 11.05-19.45) ( < 0.01). However, there was no statistically significant difference in seroprevalence in domestic black-boned sheep and goats between ages and species ( > 0.05). To our knowledge, this is the first report of seroprevalence in domestic black-boned sheep and goats in Yunnan Province, southwest China. These data provide baseline information for future implementation of measures to control infection in these animals.
该属革兰氏阴性菌可在人类和动物中引发多种疾病。中国国内黑骨绵羊和山羊中该菌的血清阳性率尚不清楚。在本次调查中，2017年7月至8月从中国西南部云南省三个县的家养黑骨绵羊和山羊中随机采集了481份血清样本。采用间接血凝试验（IHA）检测血清。在100/481份[20.79%，95%置信区间（CI），17.16 - 24.42]血清样本中检测到针对该菌的抗体（IHA效价≥1:64）。云南省不同地区该菌的血清阳性率在12.21%（95% CI，7.81 - 16.61）至30.89%（95% CI，22.72 - 39.06）之间，差异具有统计学意义（P < 0.01）。家养黑骨绵羊和山羊中雄性的血清阳性率（28.64%；95% CI，22.36 - 34.92）显著高于雌性（15.25%；95% CI，11.05 - 19.45）（P < 0.01）。然而，家养黑骨绵羊和山羊中该菌的血清阳性率在年龄和物种之间无统计学显著差异（P > 0.05）。据我们所知，这是中国西南部云南省家养黑骨绵羊和山羊中该菌血清阳性率的首次报告。这些数据为今后实施控制这些动物感染该菌的措施提供了基线信息。
