2013年1月至4月期间，在坦桑尼亚恩戈罗恩戈罗牲畜-野生动物生态系统中对非特征性家犬进行的横断面研究中确定了绦虫病的患病率。通过使用福尔马林-乙醚沉降技术筛选粪便样品来确定绦虫卵。根据人口统计学、饲养和管理数据评估犬感染的易感因素。在205份粪便样本中，150份（73.2%）对带绦虫卵呈阳性。1岁以下、1-3岁和3岁以上犬带绦虫卵检出率分别为80%、30.2%和75.3%。犬的年龄组和性别患病率无显著差异（P > 0.05），但雌性患病率（73.8%）略高于雄性（72.7%）。在Waso（80.6%）和Endulen（75%）的犬粪便中发现绦虫卵的可能性显著高于马兰博（63.2%，P < 0.05）。研究表明，农牧民拥有和饲养的狗感染带绦虫的风险较低。感染率（P = 0.001）高于牧民饲养的。大部分狗主并不知道感染绦虫的诱因及传播途径。狗经常被喂食内脏，修剪和屠宰动物的头部，他们没有治疗寄生虫感染。这项研究的结果表明，绦虫病在恩戈罗恩戈罗的非描述性狗中流行，强调需要进一步研究和积极监测，以更好地了解绦虫属的传播周期。在坦桑尼亚更广泛的地理区域。
The prevalence of taeniasis was determined during the period January to April 2013 in a cross-sectional study of non-descript domestic dogs from the livestock–wildlife ecosystem of Ngorongoro, Tanzania. Taeniid eggs were determined by screening faecal samples using the formalin-ether sedimentation technique. Predisposing factors for dog infection were assessed in relation to demographic, husbandry and management data. Of the 205 faecal samples screened, 150 (73.2%) were positive for taeniid eggs. The prevalence of dogs harbouring taeniid eggs was 80%, 30.2% and 75.3% in the less than 1 year, 1–3 years and greater than 3 years of age groups, respectively. Age group and sex prevalence in dogs did not differ significantly (P > 0.05), although the females showed a marginally higher prevalence (73.8%) in comparison to the males (72.7%). Taeniid eggs were significantly more likely to be found in the faeces of dogs located in Waso (80.6%) and Endulen (75%) than in Malambo (63.2%, P < 0.05). The study revealed that dogs owned and raised by agro-pastoralists were at a lower risk of acquiring Taenia spp. infection (P = 0.001) than those that were raised by pastoralists. The majority of dog owners were not aware of the predisposing factors and the mode of transmission of taeniids. Dogs were frequently fed on viscera, trimmings and the heads of slaughtered animals, and they were not treated for parasitic infections. The findings of this study indicate that taeniasis is prevalent among non-descript dogs in Ngorongoro, underscoring the need for further research and active surveillance to better understand the transmission cycle of Taenia spp. in a wider geographical area in Tanzania.
