Cysticercus tenuicollis infection, which can cause production and economic losses in livestock, is neglected in most African countries, including Cameroon.
To determine the prevalence, intensity and associated factors of C. tenuicollis in small ruminants in the Northwest region, Cameroon.
A total of 1106 small ruminants (493 sheep; 613 goats) originating from divisions of the study region and destined for slaughter in Bamenda municipality were examined. Following slaughter, intensive meat inspections were performed to detect C. tenuicollis cysts based on standard procedures.
Overall, the prevalence of C. tenuicollis was 34.36% (31.62%-37.21%), and no difference (χ = 1.43, p = 0.23) was observed between goats (35.89% [32.19%-39.76%]) and sheep (32.45% [28.47%-36.70%]). C. tenuicollis cyst was prevalent in all divisions in the region and detected during the entire study period. Weight, body condition score, pregnancy and lactating status of females, origin of the animals and season were the major (p < 0.05) factors in goats and only age (p < 0.05) in sheep. C. tenuicollis cysts were predominant in the abdominal cavity (97.90%) (OR = 2477.79; 889.45-6902.46; p < 0.0001, χ = 701.19) and mainly attached to the omentum (71.84%) (OR = 20.03; 13.53-29.66; p < 0.0001, χ = 269.13) compared to the pelvic cavity and other organs, respectively.
The study showed high prevalence and widespread distribution of C. tenuicollis infection in small ruminants and suggested that cysticercosis in small ruminants and its associated socio-economic implications for livestock production are neglected in Northwest Cameroon. Concerted veterinary-livestock farmer efforts, monitoring of infected small ruminant populations and regular parasite control in dogs in contact with small ruminants and prevention of contamination of pastures with T. hydatigena eggs by barring access of potential definitive hosts are essential for the control of the disease.
细颈囊尾蚴感染可导致家畜生产和经济损失，在包括喀麦隆在内的大多数非洲国家都被忽视。
确定喀麦隆西北地区小型反刍动物中细颈囊尾蚴的流行率、感染强度及相关因素。
对来自研究区域各分区、 destined for slaughter in Bamenda municipality的1106只小型反刍动物（493只绵羊；613只山羊）进行检查。屠宰后，按照标准程序进行详细的肉类检查，以检测细颈囊尾蚴囊肿。
总体而言，细颈囊尾蚴的流行率为34.36%（31.62%-37.21%），山羊（35.89% [32.19%-39.76%]）和绵羊（32.45% [28.47%-36.70%]）之间未观察到差异（χ = 1.43，p = 0.23）。细颈囊尾蚴囊肿在该地区所有分区均有流行，且在整个研究期间均有检测到。体重、体况评分、雌性动物的妊娠和泌乳状态、动物来源及季节是山羊感染的主要（p < 0.05）因素，而在绵羊中只有年龄（p < 0.05）是主要因素。细颈囊尾蚴囊肿主要位于腹腔（97.90%）（OR = 2477.79；889.45-6902.46；p < 0.0001，χ = 701.19），主要附着于大网膜（71.84%）（OR = 20.03；13.53-29.66；p < 0.0001，χ = 269.13），与盆腔和其他器官相比。
该研究表明小型反刍动物中细颈囊尾蚴感染的流行率很高且分布广泛，提示喀麦隆西北部地区小型反刍动物的囊尾蚴病及其对家畜生产的相关社会经济影响被忽视。兽医和养殖户的共同努力、对感染小型反刍动物群体的监测、对与小型反刍动物接触的犬类进行定期寄生虫控制以及通过禁止潜在终末宿主进入来防止牧场被多头绦虫虫卵污染对于控制该病至关重要。 （注：“destined for slaughter in Bamenda municipality”这里原英文表述不太完整准确，推测可能是运往巴门达市屠宰之意，翻译时只能尽量按此理解来表达。）
