Intestinal trichomoniasis

Introduction to trichomoniasis Trichomonas vaginalis is a flagellate that is parasitic in the intestine. It is more common in the cecum and colon, and can cause clinical symptoms such as diarrhea. It is also known as intestinal trichomoniasis. basic knowledge The proportion of illness: 0.0035% Susceptible people: no specific people Mode of infection: non-infectious complication:

Causes of trichomoniasis

(1) Causes of the disease

Trichomonas vaginalis is similar in morphology to Trichomonas vaginalis but the fluctuating membrane and the base staining rod are longer until the posterior end of the worm body. The posterior flagella are parallel to the left side of the undulating membrane and protrude from the anterior end of the worm body. In the unsuitable environment, false capsules can be formed, and the worms can obtain nutrients by swallowing, phagocytosis, etc. The trophozoites are parasitic in the human colon and propagated by the vertical splitting method. The trophozoites are discharged with the diarrhea and can survive at room temperature. Day; soil can survive for 7 days, people are infected by food or water contaminated by trophozoites, and can also be spread by flies and the like.

(two) pathogenesis

Trichomonas vaginalis can cause intestinal mucosal congestion, edema and inflammatory reaction, mucosal epithelial cell necrosis, lymphoid follicle small abscess formation, when the host resistance declines, in the presence of intestinal symbiotic bacteria, the worms multiply, mucosal damage Obviously aggravated, the number of diarrhea increased, the active movement of Trichomonas caused strong mechanical stimulation, causing hypersecretion of the gland, the worm has more lysosomes, rich in acid phosphatase and other hydrolase, a large number of worms Released lysosomal enzymes can degeneration, necrosis and diarrhea of intestinal mucosal epithelial cells.

Trichomoniasis prevention

The prevention measures for human trichomoniasis are the same as intestinal infectious diseases.

Trichomoniasis complications Complication

Can be complicated by biliary trichomoniasis.

Symptoms of trichomoniasis common symptoms abdominal pain loss of appetite high fever diarrhea nausea constipation bloating

The disease is distributed throughout the year, in summer and autumn, the onset can be slow and urgency, the course of disease varies from a few hours to more than 20 years, diarrhea is the main symptom, thin paste, may have mucus but pus and blood is rare, several times a day to More than ten times, with nausea and vomiting, abdominal pain, bloating, loss of appetite, etc., about 1/5 patients have moderate to low fever, high fever is rare, a small number of patients show diarrhea, alternating constipation, human trichomoniasis can cause upper right when parasitic Abdominal paroxysmal pain, nausea and vomiting, fever and increased white blood cell count, intestinal trichomoniasis should be differentiated from other diseases causing diarrhea, biliary parasitis should be distinguished from bacterial biliary infection.

Examination of trichomoniasis

Intestinal trichomoniasis can be directly smear microscopically or positively cultured by feces.

Diagnosis and identification of trichomoniasis

Finding worms in feces and bile is the basis for diagnosis.

Intestinal trichomoniasis should be differentiated from other diseases that cause diarrhea, and biliary parasitis should be distinguished from bacterial biliary infection.
