Abstract:
The whipworm,Trichuris trichiura,has a worldwide distribution but is more common in tropical and subtropical areas and in regions where sanitation is poor.The common name of whipworm is most descriptive,the thick posterior part of the body forming the stock,and the long thin anterior portion.The adult worma are from 3 to 5 cm long,the female worm is longer than the male worm.On the posterior part is pinkish gray and contains the intestine and reproductive organs. Diagnosis is by demonstraion of the characteristic barrel-shaped eggs (50-54 by 22-23μm)usually found in the stool.But their morphology of adult worms and eggs among the human,domestic and wild animals are quite different to diagnosis.The females are larger(35-55 mm long)than the males(30-45 mm).Each female worm can produce 3,000 to 70,000 eggs daily.The eggs are lemon-like with a plug at each end.Their size are 50-54 μm and 22-23 μm respetively.
