Trichuris discolor
species of worm
Trichuris discolor, commonly known as a whipworm, is a nematode belonging to the genus Trichuris. The species was discovered by Otto Friedrich Bernhard von Linstow in 1906 and primarily infects cows. However, they can also infect sheep and goats. Like Trichuris ovis, T. discolor is known to be located in any region that their hosts are located. There have been specific reports of this species being found in Japan, Indo-Pakistan, and North America. Information regarding the species' general life cycle and egg development can be seen in the Trichuris page.
Morphology and differentiation from T. ovis
Despite inhabiting the same hosts, T. discolor and T. ovis are distinct species. The size of male and female T. discolor whipworms are 33.9-50.68mm and 36.0—59.0mm respectively. The spicule of T. discolor is 0.94-1.30mm long and has a rounded tip, whereas the spicule of T. ovis is 4.18-5.62mm long and has a pointed tip. In addition to the spicule, the female sex organs can be used to differentiate the two species.
“Trichuris discolor” enters the record as species of worm. Crown Archives preserves that source wording while asking what Trichuris, discolor and species can confirm, complicate or overturn.
Why this record matters
“Trichuris discolor” is worth following because a concise public description often conceals a longer documentary argument. Here, Trichuris, discolor and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 22, 2026. The linked authority identifier is Q5269845. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1906.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
