Harm When Infected With Paragonimus Lung Fluke

Causes of disease: Fascioliasis is caused by trematodes of the genus Paragonimus. Out of 40 types of lung fluke, there are more than 10 types of human pathogens and mainly Paragonimus westermani, while in Vietnam is Paragonimus heterotremus
The flukes of lungs are as big as coffee beans (equal to small peanuts), 7-13 mm long, 4- 6 mm wide, red or white pink. Eggs of lung fluke are oval, gray and have a lid. Eggs size: 80 -100 um * 50 -67 um. The bisexual flukes on a flukes have both male and female genitals, mainly parasitic in the lungs, they nest in the bronchus of human or animal lungs, in each flukes most have two and reddish fluid

. , surrounded by fibrous shells with new blood vessels.
The cycle of pulmonary fluke
Flukes in the lungs to eggs, eggs sputum through the throat out or under feces when swallowing sputum, eggs fall into the water
In the environment, the egg grows and hatches the larvae.
The larvae enter the snails to develop into tail larvae
Tail larvae leave snails that swim freely in the water, invade freshwater shrimp and crabs, and lose their tail to develop into cyst larvae found in meat and viscera of shrimp and crab
People and animals accidentally eat shrimp and crabs with uncooked cyst larvae such as grilled crabs, crab sauce, and when eaten: larvae enter the stomach and intestines, through the diaphragm and pleura. bronzer to nest there
The time from eating the larvae to the maturation tapeworm is about 5-6 weeks.

Harm of the disease: Flukes of the lung parasites in the lungs create abscess in the bronchi of the lungs coughing up blood, can break the abscess causing pneumothorax, pleural effusion and death. Flukes are parasitic in the pleura, causing pleural effusion in the pleura can be parasitic in other places such as the brain, sometimes in the spinal cord, pectoral muscle or under the skin, spleen, large junction, in the abdomen. , pericardium and cardiac muscle, mediastinum, uterus, fallopian tubes, ovaries, testes and ureters cause complex and dangerous symptoms.
How to prevent lung fluke disease?
Communication education not to eat undercooked crabs and crabs is a good measure to prevent.
