Sixteen non-infected control pigs housed together with 16 pigs infected with Trichuris suis, excreted T. suis eggs in their faeces (range 20-4, 960 eggs per gram faeces (EPG)). When the control pigs were moved to clean pens, their egg counts dropped to zero EPG within five days. A significant correlation was found between T. suis egg counts of infected and control pigs penned together (r = 0.89, P < 0.001). These results suggest that false-positive faecal egg counts may be the result of coprophagia.
16只未感染的对照猪与16只感染猪蛔虫的猪饲养在一起，对照猪在粪便中排出猪蛔虫卵（每克粪便中虫卵数范围为20 - 4960个）。当对照猪转移到干净的猪舍时，它们的虫卵计数在五天内降至零每克粪便虫卵数（EPG）。发现饲养在一起的感染猪和对照猪的猪蛔虫卵计数之间存在显著相关性（r = 0.89，P < 0.001）。这些结果表明，粪便虫卵计数假阳性可能是食粪癖的结果。
