Human trichuriasis is a neglected tropical disease which affects millions of people worldwide, mostly living in low socio-economic conditions. Numerous studies have been conducted over the past 10 years to compare the different techniques for T. trichiura eggs detection. Our study provides the first geometric morphometric analysis for the specific detection of eggs of Trichuris sp. isolated from stools of macaque (M. sylvanus), colobus (C. g. kikuyensis), grivets (C. aethiops) and the Brazza's monkey (C. neglectus) from zoos in Spain. Principal Component Analysis (PCA) arises as an efficient method to determine Trichuris spp. eggs. The selected measurements to be included in the PCA were proposed for the first time in the present work, as far as we know, as we could not find previous studies reporting standardized parameters.

人滴虫病是一种被忽视的热带病，影响了全球数百万人，其中大多数生活在低社会经济条件下。在过去的十年中，已经进行了许多研究，以比较不同的技术检测毛tri虫卵。我们的研究为Trichuris sp。卵的特异性检测提供了第一个几何形态计量学分析。从西班牙动物园的猕猴（M. sylvanus），疣猴（C. g。kikuyensis），沙ive（C. aethiops）和Brazza的猴子（C. neglectus）的粪便中分离出来。主成分分析（PCA）成为确定Trichuris的有效方法spp。蛋。据我们所知，由于我们无法找到以前的报告标准参数的研究，因此本工作中首次提出了要包括在PCA中的选定测量。
