Trichuriasis, also known as whipworm infection, is an infection by the parasitic worm Trichuris trichiura (whipworm). [2] If the infection is only with a few worms, there are often no symptoms. [1] In those who are infected with many worms, there may be abdominal pain, fatigue and diarrhea. [1] The diarrhea sometimes contains blood. [1]
Trichuris serrata, commonly known as a whipworm, is a nematode of the genus Trichuris first discovered in domestic Brazilian cats by Dr. Otto Friedrich Bernhard von Linstow in 1879.

Its common name "whipworm" refers to the shape of these worms; they look like whips with wider "handles" at the posterior end.

Whipworm: Trichuris trichiura, Trichuris vulpis: large intestine, anus stool (eggs) common worldwide accidental ingestion of eggs in dry goods such as beans, rice, and various grains or soil contaminated with human feces Elephantiasis – Lymphatic filariasis: Wuchereria bancrofti: lymphatic system thick blood smears stained with hematoxylin.
Three types of soil-transmitted helminthiasis can be distinguished: ascariasis, hookworm infection and whipworm infection. These three types of infection are therefore caused by the large roundworm A. lumbricoides, the hookworms Necator americanus or Ancylostoma duodenale and by the whipworm Trichuris trichiura.
Trichuris suis is a whipworm; the variations in thickness of the anterior and posterior segments give the parasite the characteristic "whip-like" appearance. Adult females measure 6 to 8 cm and adult males 3 to 4 cm. T. suis eggs are oval (60 × 25 μm) and yellow-brown with bipolar plugs. [ 1 ]
