African Swine Fever (ASF) is enzootic in Cameroon. A cross-sectional study was conducted in the center, south and south-west regions of Cameroon in order to determine: the knowledge, skills and practices at risk of pig breeders; the prevalence of the disease in piggeries; the genome of the circulating virus. A total of 684 blood samples were collected in 209 farms for RT-PCR and ELISA analyses at the National Veterinary Laboratory (LANAVET) annex in Yaoundé. Prevalences of 15.2% (95CI: 12.5-17.9%) by ELISA, 23.8% (95CI: 20.6-27.0%) by RT-PCR, and 15.2% (95CI: 12.5-17.9%) by ELISA-PCR, were recorded. Of the farmers surveyed, 90% knew about the ASF and 55.3% have already experienced it. The 47.4% of them would not be able to recognize ASF if it occurred and, according to them, the risk of the disease introduction in farms would be 32% linked to the animal health personnel who work on farms. Molecular characterization revealed that only ASF genotype-I variable 19T-RSs is circulating. ASF is still hovering at a risky rate over the pig sector of Cameroon. The control of ASF needs an epidemiological surveillance, a better involvement of all stakeholders, sensitization of breeders and an effective State support for producers.
非洲猪瘟(ASF)在喀麦隆呈地方流行性。在喀麦隆的中部、南部和西南部地区开展了一项横断面研究,以确定:养猪户面临风险的知识、技能和做法;猪场中该疾病的流行情况;传播病毒的基因组。在雅温得的国家兽医实验室(LANAVET)附属机构,共从209个农场采集了684份血样,用于逆转录聚合酶链反应(RT-PCR)和酶联免疫吸附测定(ELISA)分析。ELISA检测患病率为15.2%(95%置信区间:12.5 - 17.9%),RT-PCR检测患病率为23.8%(95%置信区间:20.6 - 27.0%),ELISA-PCR检测患病率为15.2%(95%置信区间:12.5 - 17.9%)。在接受调查的养殖户中,90%了解非洲猪瘟,55.3%曾经历过该病。其中47.4%的人表示如果非洲猪瘟发生,他们无法识别,据他们说,该病传入农场的风险有32%与在农场工作的动物卫生人员有关。分子特征分析显示,只有非洲猪瘟基因型-I可变19T-RSs在传播。非洲猪瘟在喀麦隆的养猪业中仍处于高风险水平。非洲猪瘟的防控需要进行流行病学监测,所有利益相关者更好地参与,对养殖户进行宣传,并由国家为生产者提供有效支持。
