Genetic heterogeneity and phylogeny of Trichuris spp. from captive non-human primates based on ribosomal DNA sequence data

The tendency to associate Trichuris sp. to host species can lead to misleading taxonomic interpretations (i.e. whipworms found in primates are identified as T. trichiura). The results here obtained confirm previous evidences suggesting the existence of Trichuris spp. other than T. trichiura infecting non-human living primates.
