在低收入国家控制猪带绦虫的努力一直不成功或不可持续。这可能表明我们对寄生虫传播动力学的理解中存在“缺失环节”，并可能表明环境污染的严重程度。我们的目的是确定与猪囊尾蚴病的病例对照研究设计，利用已知的持续或多次感染猪囊尾蚴病的信息。该研究结合了问卷访谈和观察性调查，于2014年7月在坦桑尼亚的Mbeya和Mbozi两个地区进行。根据猪囊虫病患病率的状态确定研究家庭，并根据既往猪囊虫病的存在情况将其分配至病例组或对照组。这导致来自20个村庄的43名农民进入病例组，50名农民进入对照组。据说有46%的农民把土豆皮生吃或煮了喂猪。基于逻辑回归，猪囊虫病可能与没有或完全开放的厕所（p = 0.035，OR 5.98，CI：1.33-43.02）相比，封闭的厕所。给猪喂土豆皮也与感染风险增加相关（p = 0.007，OR 3.45，CI：1.43-8.79）。包括猪管理系统的逻辑分析表明，与水泥地板相比，饲养在高架围栏（p = 0.049，OR 5.33，CI：1.08-32.27）和泥土地板（p = 0.041，OR 9.87，CI：1.29-114.55）上的猪更容易感染。土豆皮在到达家庭之前是否被带绦虫卵污染，或者污染是否来自水或剥皮过程中的脏手，仍有待证实。这项研究表明，对猪管理的一些领域进行详细评估对于设计有效的控制方案至关重要。(C)2015爱思唯尔B.

Attempts to control Taenia solium in low-income countries have been unsuccessful or unsustainable. This could indicate a 'missing link' in our understanding of the transmission dynamics of the parasite and possibly the magnitude of environmental contamination. We aimed to identify risk factors associated with porcine cysticercosis using a case-control study design, utilising known information on persistent or multiple infections of porcine cysticercosis. The study, a combination of questionnaire interviews and observational surveys, was conducted in July 2014 in the two districts Mbeya and Mbozi, Tanzania. Study households were identified based on their status regarding porcine cysticercosis prevalence and allocated into cases or controls based on previous porcine cysticercosis presence. This resulted in 43 farmers in the case group and 50 farmers in the control group, from 20 villages. Potato peels were said to be given to pigs either raw or boiled by 46% of the farmers. Based on logistic regression porcine cysticercosis could be associated with absence or a completely open latrine (p = 0.035, OR 5.98, CI: 1.33-43.02) compared to an enclosed latrine. Feeding potato peels to pigs was also associated with increased risk of infection (p = 0.007, OR 3.45, CI: 1.43-8.79). Logistic analysis including the pig management system indicated pigs kept in elevated pens (p = 0.049, OR 5.33, Cl: 1.08-32.27) and on a dirt floor (p = 0.041, OR 9.87, CI: 1.29-114.55) were more likely to be infected compared to a cemented floor. Whether potato peels are contaminated with Taenia eggs before they reach the household or whether the contamination is from water or dirty hands during the process of peeling, remains to be confirmed. This study suggests that detailed assessment of a number of areas of pig management is essential for designing effective control programmes. (C) 2015 Elsevier B.V. All rights reserved.
