The structure of vulva of four Trichocephalus species has been studied using scanning electron microscopy (SEM). The shape of vulva and cuticular elements on vulval appendages is described and documented. The cuticular structures on the vulva have a characteristic shape specific for each species. It is suppossed that SEM can be successfully employed in a detailed study of vulval structure, which is an important taxonomic character for the differentiation of females of Trichocephalus species.

Long-term occurrence of Trichuris species in wild ruminants in the Czech Republic

Reliable molecular differentiation of Trichuris ovis and Trichuris discolor from sheep (Ovis orientalis aries) and roe deer (Capreolus capreolus) and morphological characterisation of their females: morphology does not work sufficiently

The first determination of Trichuris sp. from roe deer by amplification and sequenation of the ITS1-5.8S-ITS2 segment of ribosomal DNA
