Taeniasis
Introduction
Introduction to rillworm Raillietiniasis is a disease caused by the parasitic human intestinal tract of the raillietinacelebensis. Generally no special symptoms, there may be night molars, loss of appetite, abdominal pain, diarrhea, anemia and so on. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: digestive tract spread Complications: anemia optic atrophy
Cause
Cause of tsutsugamushi disease
(1) Causes of the disease
The adult is 32cm long and 0.2cm wide. It has 185 segments, the head section is obtuse, and the transverse diameter is 0.46cm. The four suction cups are all decorated with fine thorns. The apex is often shrunk in the shallow convex pockets around it. There are two rows of axe-shaped hooks with a length of about 72. The mature section contains dozens of egg-shaped testes, one side has genital holes, the penis sac, the drainage tube, and the two leaves are butterfly-winged, followed by The yolk gland, the gestational section is continuous like a rosary, filled with oocysts, each sac contains 1 to 4 eggs, olive-shaped, 45m × 27m in size, with a rounded six-hooked cockroach in the middle, adult parasitic rodents, occasionally seen in humans, pregnant The detachment is excreted with the feces, and the eggs develop into cysticercus in the genus of cardiocondylanula. The ant is the intermediate host and the medium of transmission. The rats are infected by ants that ingest the cysticercosis.
(two) pathogenesis
The pathogenic action of the worm is mainly caused by the damage of the worm body to the mucosa of the host intestinal wall and the secretion of toxins. The intestinal villi parasitized by the cysticercosis appear to be swollen and degenerated, and then the proliferation of connective tissue and epithelial cells occurs. Adults The intestinal mucosa at the attachment site can be damaged, causing congestion and necrosis, and small ulcers can form, and lymphocytes and neutrophils infiltrate around the lesion.
Prevention
Resistant tsutsugamushi prevention
Prevent infection and reduce contact with pathogenic bacteria.
Complication
Residual tsutsugamushi complications Complications anemia optic atrophy
Sometimes optic nerve head edema, optic atrophy and so on. When cysticercosis dies, it can cause vitreous opacity, retinal detachment, optic atrophy, cataract, secondary glaucoma and other eyeball atrophy and blindness. Common complications cysticercosis. If a person eats a locust egg, it can also develop into a cysticercosis in the human body, and cause cysticercosis (see sac cysticercosis).
Symptom
Symptoms of tsutsugamushi disease common symptoms molars abdominal pain diarrhea appetite lack of weight loss roaching anal itching
Infected people generally have no obvious symptoms, only occasionally abdominal pain, diarrhea, anal itching and night molars, runny nose, loss of appetite or weight loss, and some patients have anemia, leukocytosis.
Examine
Inspection of rillworm tsutsugamushi
Some patients have anemia and leukocytosis.
Diagnosis
Diagnostic identification of rillworm
Most patients have white in the stool, which can excrete the size of the rice granules. Therefore, the diagnosis mainly depends on the detection of eggs and gestational tract in the feces.
The differential diagnosis is the same as the short-membrane tsutsugamushi disease.
