Helminthiases flowing predominantly gastrointestinal disorders.
trihotsefaleze Pathogen - round helminth whipworm.Female 33-55 mm long male - 30-45 mm.The eggs are brown, with stoppers at the poles, the size 0,047-0,05X0,023 mm.Southwest, hairlike, whipworm part of the body is embedded in the surface layers of the intestinal mucosa, occasionally penetrating to the submucosal and muscular layers.Thick rear of the helminth body hanging in the intestinal lumen.Whipworm parasite usually in the ileocecal region, but intensive invasion - across the large intestine.
with feces infested whipworm people allocated to the outside environment helminth eggs, which prior to the maturation of the infective stage takes place in the soil at a temperature of 15-35 ° C and sufficient moisture.Infection occurs by ingestion trihotsefaleze mature eggs from soil particles c
Pathological anatomy and pathogenesis
in the human gut of whipworm eggs hatch into larvae, which penetrate into the mucosa, where they remain for about 3 days.Then they go out into the intestinal lumen and 1 month developing in adult worms.In place of parasitism in the intestinal wall whipworm infiltrates occur predominantly eosinophils and plasma cells, and lymphoid cells from partially.Occasionally in the intestinal mucosa formed small hemorrhage, necrosis and erosion.Described education about helminth granulomatous tumor growths.Introduction of the head end of the body whipworm the intestinal mucosa traumatization leads to it, and can contribute to secondary bacterial infection.
trihotsefaleze Patients usually indicate a general malaise, fatigue, loss of appetite, salivation, nausea, sometimes vomiting, dull pain in the right iliac and epigastric region or around the abdomen.In some patients, the pain resemble observed in duodenal ulcer, which is associated with dyskinesia of the body.Sometimes, as a result of penetration of whipworm in the appendix appendicular colic attacks occur, and if a secondary infection - appendicitis.Approximately half of the patients have constipation or diarrhea alternating with it.
In tropical countries with extremely intense infestation can trihotsefalezny gemokolit accompanied children prolapse of the rectum, on the mucous membrane which can be seen a lot of whipworm.On palpation of the abdomen, tenderness in the right iliac fossa, occasionally around the abdomen.The acidity of the gastric juice is often lowered.From the nervous system often have a headache, dizziness, irritability, restless sleep.Described fleeting loss of consciousness, fainting, and even seizures.The blood is sometimes defined anemia.Eosinophilia is not always detected, often in the early phase of helminthiasis.
With a weak bot infestation occurs often obliterated.Diagnosis is based on the detection of eggs in the feces of whipworm.
- Wuchereriasis and Brug's filariasis
Treatment For treatment trihotsefaleze administered mebendazole.
necessary sanitary improvement of populated areas.Vegetables and fruits before eating should be washed thoroughly, then pour over boiling water.
