Abstract

Abstract: 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.

Trichuris spp. eggs from macaque, colobus, grivet and Brazza's monkey were analysed. The measurements included in the PCA were proposed for the first time.
