在莫桑比克太特省安戈尼亚地区进行了一项横断面研究，以确定在小农耕作制度下饲养的猪的寄生虫感染的流行率和相关的危险因素。随机抽取6个村133户262头猪。从每头猪的血液、粪便样本、全身检查和皮肤刮片中分别确定猪带绦虫(使用Ag-ELISA)、胃肠道寄生虫和体外寄生虫的流行率。对小农户进行了问卷调查，以评估他们对健康和生猪管理的知识和看法，并进行了观察性研究，以确定他们的生猪管理做法。用Ag-ELISA法检测猪囊虫病总患病率为12.6%，胃肠道线虫感染率为21.4%，艾美耳球虫感染率为21.4%。体表寄生虫占37.8%。经铜绿假单胞菌培养鉴定出4种蠕虫，分别为偏食线虫、猪圆线虫、食道口线虫和毛线虫，并通过粪卵计数鉴定出猪蛔虫和鞭虫。Hematopinus suis、Rhipicephalus spp.和鸡棘食线虫的患病率分别为32.4%、7.6%和6.9%。唯一与寄生虫流行相关的显著危险因素是猪源(村庄)，胃肠道寄生虫(OR=10.81[0.81-57.27])和体外寄生虫(OR=7.06[1.42-35.03])。这项研究提供的证据表明，猪的寄生虫感染构成了安戈尼亚地区小农户的主要负担，猪囊虫病是该地区的公共卫生威胁，需要立即关注这种寄生虫的控制和预防。
A cross-sectional study was carried out to determine the prevalence and associated risk factors of parasitic infections in pigs kept under smallholder farming system in Angonia district, Tete Province, Mozambique. A total of 262 pigs from 133 households of six villages were randomly selected. From each pig blood, faecal samples, full body searches, and skin scrapings were conducted to determine the prevalence of Taenia solium (using Ag-ELISA), gastrointestinal (GI) parasites, and ectoparasites respectively. A questionnaire survey was administered to smallholder pig farmers to assess their knowledge and perceptions of health and pig management and an observational study was conducted to determine their pig management practices. The overall prevalence of porcine cysticercosis by Ag-ELISA was 12.6%, GI nematodes 21.4%, Eimeria spp. 8.0% and ectoparasites 37.8%. Four helminths species namely, Metastrongylus spp., Hyostrongylus spp., Oesophagostomum spp., Trichostrongylus spp., were identified from by copro culture, and through faecal egg count, Ascaris suum and Trichuris suis were identified. Haematopinus suis, Rhipicephalus spp. and Echidnophaga gallinacea were found with a prevalence of 32.4%, 7.6%, and 6.9%, respectively. The only significant risk factor identified to be related to the parasite prevalence was pig origin (village), for both gastrointestinal parasites (OR=10.81[0.81-57.27]) and ectoparasites (OR=7.06[1.42-35.03]). This study provided evidence that parasitic infections in pigs constitute a major burden for smallholder pig farmers in Angonia district, and that porcine cysticercosis is a public health threat in the area and immediate attention is needed for control and prevention of the parasite.
