Is Spirometra Wire Diseases Hazardous?
Tapeworm Spirometra erinacei, also known as tapeworm, has been detected in many countries in Asia such as Vietnam, China, Taiwan, Japan, the Philippines, South Korea and India; Australia, Europe, America ... like Australia, Brazil, Puerto Rico, Hawaii .
Although there are many different definitions, most studies believe that only one species of Spirometra erinacei has been distributed in the North, Central and South of Vietnam. In humans parasites cause plerocercoid or sparganum, causing sparganosis. This term refers to the disease caused by the larval stage of the tapeworm Spirometra erinacei
1 SPIROMETRA PAINTING SHAPE
In Vietnam, according to many authors, only one species of Spirometra erinacei parasites in the small intestine of dogs and cats. The rate of Spirometra erinacei tapeworm infection in dogs varies by region, the highest is 29%, the lowest is 6%.
. Spirometra erinacei is parasitic in the dog's small intestine. The parasite has a length of about 1,000mm, a width of less than 10mm, a length of about 0.48mm, a white color, flat and a larger width than the length of a flukes.

When Coracidium comes out of the egg, it will move very strongly, can be fixed by putting in an environment with 10% formol, now observe the oval shaped coracidium. Coracidium has an average length of 42
During the S.erinacei growth cycle, when coracidium is infected with crustaceans, after 10 days, coracidium larvae develop into procercoid, when swallowed by the second intermediate host will develop into plerocercoid or sparganum. After 25 days, the proercoid in crustacea remained unchanged in morphology, but after 30 days, the procercoid will gradually degrade and calcify (Lee et al., 1990)
The plerocercoid larvae are about 35mm in length, white, with grooved head sections, and feces on the body. S.erinacei's plerocercoid larvae reward parasites in frogs, frogs, birds, and reptiles. Fish did not detect plerocercoid infection of S.erinacei.
The second intermediate host is usually a frog or a frog.
. Vertebrates are infected with plerocercoid by eating frogs and frogs infected with larvae and can be plerocercoid by drinking plerocercoid-contaminated crustacean water. Plerocercoid, also known as (Stephen, 2004) (Figures 3 and 4)
2. SPIROMETRA WIRELESS DEVELOPMENT PROCESS
Flukes are released into the uterus of the flukes in the feces out into the water. At a temperature of 15-250C after 15 days developing into coracidium larvae, surviving in water for about 12 hours. If coracidium is ingested by crustacean species of the Cyclops genus, after 2-3 weeks develop into plerocercoid larvae, the larvae are about 0.5 - 0.6mm long.
Then, if the crustaceans are eaten by frogs and clones, the plerocercoid will migrate to the second plerocercoid muscle or larvae-forming organ, about 6mm long, but not cocoon. The final hosts are predators, who eat frogs and live or uncooked frogs that will develop into adult flukes in the small intestine.
The development cycle of Spirometra tapeworm
He is not the final host of Spirometra erinacei. Other studies suggest that humans, birds, mice, and pigs are only hosts for plerocercoid accumulation of Spirometra erinacei. It should be noted that the plerocercoid (sparganum) larvae of Spirometra erinacei are capable of causing sparganosis in humans and the perocercoid larvae of Diphyllobothrium latum are not.
3. PHYSICAL CHARACTERISTICS OF WIRELESS SPIROMETRA
Sparganosis is found all over the world. The disease usually occurs in Japan, China, Korea, Indonesia and Southeast Asia (Thailand, Vietnam). In the US, 60 cases have been reported (Stephen, 2004). Africa, Australia, North and South America
People are infected by
Swallow second proceroid larvae present in intermediate host 1 (Cyclops) by drinking raw water.
Eat intermediate hosts 2 (frogs, clones, snakes, mice, birds .
...) with uncooked plerocercoid larvae.
Applying parasitic infected frog and frog meat to the wound according to folk remedies, from which the larvae move to the tissue.
4. READY FOR SPIROMETRA WIRE
Occasionally, people may be infected with the parasite in the adult stage in the small intestine, but rarely have clinical manifestations In contrast, infection with larvae sparganum or plerocercoid will cause life-threatening diseases.
The plerocercoid causes a disease called sparganosis or Spirometra erinacei by ingesting water containing procercoid-contaminated crustacean or by ingesting the uncooked second intermediate host containing plerocercoid. Sparganum travels to the muscles and connective tissue under the skin, especially around the eyes, causing swelling and inflammation. Some cases of larvae can enter the brain.
Sparganosis in the eye.
In some Southeast Asian countries, some people have a habit of using frog meat to cover the eye for treatment, so it often results in Sparganosis in the eye. The disease is also found in the southeastern United States, parts of the Americas and East Africa (Bowman et al. 2002)
