Comparative study of four species of Trichuris roederer, 1761 (Nematoda, Trichurinae) by scanning electron microscopy

Abstract

A comparative morphological study of Trichuris travassosi, T. vulpis, T. discolor and T. suis was perfomed using scanning electron microscopy. Cuticular inflation associated with the bacillar band, vulva and male external genital appendages were analyzed. Qualitative and quantitative analyses of these structures were made for each species; they are of taxonomic value.
