Acanthocephalus macrocephalus
Introduction
Introduction to giant acanthosis Mycoticoptosis (macracanthorhynchiasis) is caused by the parasitic intestine of the giant canine (Macrocanthorhushirudinaceus), which is a zoonotic parasitic disease. basic knowledge The proportion of illness: 0.02% Susceptible people: no special people Mode of infection: digestive tract spread Complications: intestinal obstruction
Cause
The cause of the giant-stinging echinococcosis
(1) Causes of the disease
Adults are milky white or reddish, with obvious transverse wrinkles on the body surface, especially in the front of the body, cylindrical, thick at the front end, tapered at the back end, rounded at the end, and the whole body is made up of a kiss, neck and torso The three-part composition, the kiss is spherical and retractable. There are 5 to 6 rows of sharp and transparent kiss hooks in each week. Each row is 6 and arranged in a spiral shape. The neck is short and cylindrical. It is connected with the kiss sheath and has no mouth. In the digestive tract, nutrients are absorbed from the body surface. The size of the female is about (20 ~ 65) cm × (0.4 ~ 1.0) cm, and the size of the male is about (5 ~ 10) cm × (0.3 ~ 0.5) cm. Oval, dark brown, about (67 ~ 110) m × (40 ~ 65) m, egg shell thick, composed of three layers, mature eggs contain a larva - spines (Figure 1), The adult parasitic pig small intestine, the eggs are discharged with the feces, can survive in the soil for several months, the eggs are swallowed by beetles, beetles and other beetles, penetrate the intestinal wall into the body cavity to form cysts, and develop into infection after 2 to 3 months. The larvae (thorns), after being swallowed by pigs, mature and lay eggs from February to March. People may be infected by accidental ingestion of drinking water or food contaminated by intermediate hosts or spines, but people are not Suitable insect host, so in the human body, it is mostly not acanthocephalan maturation and spawning.
(two) pathogenesis
People can be infected by swallowing drinking water or food contaminated by intermediate hosts or spines.
Prevention
Giant acanthosis prevention
1. The pig's feces should be treated harmlessly. The sick pig feces are piled up for fermentation to kill eggs.
2. Do not eat crickets or chafers in areas where the disease is endemic, and pay special attention to the education of children.
Strengthen health propaganda, do not eat beetles, pigs are captive, feeds avoid beetles, such as pigs have been infected with viable deworming treatment.
Complication
Giant acanthosis Complications, intestinal obstruction
Complications include intestinal perforation or intestinal obstruction.
Symptom
Giant acanthosis symptoms common symptoms diarrhea weight loss night insomnia acute abdomen nausea intestinal perforation
Symptoms are related to the number of parasitic insects, most of which are 1. Patients may have paroxysmal abdominal pain, diarrhea, weight loss, anemia, and neuropsychiatric symptoms such as nausea, vomiting, insomnia, and night terror. A few may have intestinal perforation or intestinal obstruction. Some patients may have abdomen and abdomen mass.
Examine
Check of giant acanthosis
Fecal eggs were found by stool examination (smear method, precipitation method).
Diagnosis
Diagnosis and identification of giant acanthosis
Mainly based on clinical manifestations and the history of beetles, individual patients can be excreted by taking anthelmintic drugs, or they can be identified by morphological features when they are found in surgery for acute abdomen.
But it needs to be differentiated from ginger worm disease.
