The prevalence of Taenia solium cysticercosis in slaughter pigs and of taeniid ova in hospital patients were determined in the Nsukka area of Enugu State, Nigeria, in March 1986-September 1988 and May 1986-May 1988, respectively. Cysticercus cellulosae were detected in the pigs by ante-mortem examination of the pigs' tongues and detailed post-mortem examination of the dressed pig carcasses using standard meat-inspection procedures. Human infection was assessed by examining iodine-stained stool samples collected from patients from one selected hospital in the study area. Over 20% (483) of the 2358 trade pigs examined were found infected with C. cellulosae. Most of the cases were generalized, all the musculature being heavily infested with live cysticerci. The age and sex of the pig and the season of the year in which it was examined had no significant effect on the occurrence of cysticerci in the animals (P > 0.01) but there was a highly significant year-to-year decrease (P < 0.001) in the prevalence of cysticerci. The overall prevalence of taeniid ova in the 1525 human-stool samples analysed was 8.6%, most (78.6%) of the cases occurring in adults aged > 30 years. The epidemiological factors which might have influenced these results are identified and discussed, and suggestions are made for the control of this important zoonosis.
分别于1986年3月至1988年9月以及1986年5月至1988年5月，在尼日利亚埃努古州Nsukka地区测定了屠宰猪中猪带绦虫囊尾蚴病的流行情况以及医院患者中带绦虫卵的情况。通过对猪舌进行宰前检查，并使用标准的肉类检验程序对屠宰后的猪胴体进行详细的宰后检查，来检测猪体内的猪囊尾蚴。通过检查从研究区域一所选定医院的患者那里收集的碘染色粪便样本，来评估人类感染情况。在检查的2358头交易猪中，超过20%（483头）被发现感染了猪囊尾蚴。大多数病例为全身性感染，所有肌肉组织都被活的囊尾蚴严重侵扰。猪的年龄、性别以及检查的年份季节对动物体内囊尾蚴的发生没有显著影响（P>0.01），但囊尾蚴的流行率有极显著的逐年下降（P<0.001）。在分析的1525份人类粪便样本中，带绦虫卵的总体流行率为8.6%，大多数病例（78.6%）发生在30岁以上的成年人中。确定并讨论了可能影响这些结果的流行病学因素，并就控制这种重要的人畜共患病提出了建议。
