Most government published statistics of C. bovis prevalence in Botswana emanate mainly from records available at the Botswana Meat Commission (BMC), the country’s national export abattoir. Although BMC slaughters 44% of Botswana’s annual cattle slaughter, prevalence data arising from BMC does not reflect prevalence from lower throughput abattoirs and potential hotspots. Thus, reporting national prevalence rate using solely BMC statistics may not be very informative and reflective of the bigger picture. It therefore became imperative to probe prevalence of bovine cysticercosis using a cross-sectional study through passive abattoir inspection, covering a wider scope (more regions) and some lower throughput abattoirs previously not accounted for. Furthermore, non-participatory interview using structured questionnaires was employed to actively elicit prevalence information directly from meat industry stake holders. Prevalence arising from survey was used to compare and query results from statutory (traditional) passive abattoir method. Abattoir prevalence was 17.17% (SE = 1.70027), and survey prevalence was 42.35%; both of which were higher than published prevalence of 13.5% and BMC prevalence of 10% (SE = 0.006576). Survey method was more holistic than passive abattoir method, by covering more frontiers thus yielding higher prevalence. At p = 025, abattoir and survey prevalence were significantly different from each other. In addition to delimitating novel hotspots in Botswana, this study showed significant difference, p = 0.002 in prevalence within districts and regions. Kalagadi district’s prevalence differed significantly from other districts: differed from North East at p = 0.042, Central district at p = 0.002 and Ghanzi at p = 0.004. The results which arise from this methodological approach have been able to provide a more all-inclusive and reliable prevalence rate.

使用被动屠宰场验尸和向博茨瓦纳农民积极投予结构化非参与式问卷调查牛牛囊虫患病率

大多数政府发布的博茨瓦纳牛肝菌流行率统计数据主要来自该国国家出口屠宰场博茨瓦纳肉类委员会(BMC)的记录。尽管BMC屠宰了博茨瓦纳每年的牛屠宰量的44%,但BMC的流行率数据并未反映出较低的屠宰场和潜在热点的流行率。因此,仅使用BMC统计数据报告全国患病率可能并不能提供太多信息,也无法反映出更大的情况。因此,有必要通过无源屠宰场检查进行横断面研究来调查牛囊尾osis病的患病率,该研究涵盖了更广泛的范围(更多区域)和一些以前未曾解释过的较低产量的屠宰场。此外,使用结构化问卷的非参与式访谈直接从肉类行业利益相关者那里主动获取患病率信息。调查产生的患病率用于比较和查询法定(传统)被动屠宰场方法的结果。屠宰场患病率为17.17%(SE = 1.70027),调查患病率为42.35%;两者均高于公布的13.5%的患病率和BMC的10%的患病率(SE = 0.006576)。调查方法比被动屠宰方法更具整体性,因为它涵盖了更多领域,因此患病率更高。在p = 025时,屠宰场和调查的患病率显着不同。除了划定博茨瓦纳的新热点,这项研究还显示出地区和区域内的患病率存在​​显着差异,p = 0.002。卡拉加迪地区的患病率与其他地区有显着差异:东北地区的p = 0.042,中部地区的p = 0.002和甘孜州的p = 0.004。从这种方法学方法得出的结果已经能够提供更加全面和可靠的患病率。
