The presence of large Trichuris spp. eggs in human faecal samples is occasionally reported. Such eggs have been described as variant Trichuris trichiura or Trichuris vulpis eggs. Within the frame of a randomised controlled trial, faecal samples collected from 115 Bulang individuals from Yunnan, People's Republic of China were subjected to the Kato-Katz technique (fresh stool samples) and the FLOTAC and ether-concentration techniques (sodium acetate-acetic acid-formalin (SAF)-fixed stool samples). Large Trichuris spp. eggs were noted in faecal samples with a prevalence of 6.1% before and 21.7% after anthelminthic drug administration. The observed prevalence of standard-sized T. trichiura eggs was reduced from 93.0% to 87.0% after treatment. Considerably more cases of large Trichuris spp. eggs and slightly more cases with normal-sized T. trichiura eggs were identified by FLOTAC compared to the ether-concentration technique. No large Trichuris spp. eggs were observed on the Kato-Katz thick smears.
人体粪便样本中偶尔会发现大型毛首鞭形线虫属虫卵。此类虫卵曾被描述为变异的人鞭虫卵或狐鞭虫卵。在一项随机对照试验中，对从中华人民共和国云南省115名布朗族个体采集的粪便样本进行了改良加藤厚涂片法（新鲜粪便样本）以及FLOTAC法和乙醚沉淀法（乙酸钠 - 乙酸 - 甲醛（SAF）固定粪便样本）检测。在粪便样本中发现了大型毛首鞭形线虫属虫卵，驱虫药物给药前的患病率为6.1%，给药后的患病率为21.7%。治疗后，观察到标准大小的人鞭虫卵患病率从93.0%降至87.0%。与乙醚沉淀法相比，FLOTAC法检测出的大型毛首鞭形线虫属虫卵病例明显更多，正常大小的人鞭虫卵病例也略多。在改良加藤厚涂片上未观察到大型毛首鞭形线虫属虫卵。
