In a study conducted in the rural town of Eruwa on the role of pigs in the epidemiology of human Ascaris infection, adults of Ascaris lumbricoides were recovered from individuals and pigs living in close contact within the households and sharing common refuse dumps for defaecating and scavenging. An attempt to infect clean piglets experimentally with A. lumbricoides from infective egg stages which were cultured from the eggs recovered from the human faeces failed as no eggs were shed by the piglets 42 days after experimental feeding. Survey of faeces of humans and pigs in sampled households in the town had earlier showed that Ascaris is endemic in the human and pig populations.
在埃鲁瓦镇开展的一项关于猪在人类蛔虫感染流行病学中作用的研究中，从生活在家庭中密切接触且共用粪便倾倒和觅食垃圾场的人和猪体内采集到了蛔虫成虫。尝试用从人类粪便中回收的虫卵培养出的感染性虫卵阶段的蛔虫对健康仔猪进行实验性感染，但实验喂食42天后仔猪未排出虫卵，实验失败。此前对该镇抽样家庭中人和猪的粪便调查表明，蛔虫在人类和猪群中均为地方病。
