Fish tapeworm

Definitive host: Humans, cats and bears.

Intermediate host: Water flea, small vertebrates, fish and other crustaceans.

Prevalence & Distribution: Eastern Europe, Uganda, Chile, North and South America, Scandinavia, western Russia, the Baltics, African countries and in some Asian countries where there is more consumption of freshwater fish.

Mode of infection: Man who has the adult tapeworm excretes the eggs along with the feces. The eggs hatch out under optimum conditions into the ciliated larvae (coracidia). This is then ingested by the first intermediate host like the small crustacians. The crustaceans are then ingested by small freshwater fishes and the larvae develops into the sparganum which migrates into the tissue of the fish. When fishes, which harbor the larvae, are consumed by man in the raw state, the sparganum enter the human intestine and develops into an adult tapeworm. Sometimes the sparganum does not mature but moves about in the tissue and gets lodged in the sensitive areas of the eye or brain.

Symptoms: It competes with the host for the absorption of vitamin B12 in the small intestines. Hence the patient becomes deficit in vitamin B12 and suffers from Pernecious anemia. Intestinal blockage by worms can cause gastrointestinal symptoms. Symptoms of pernicious anemia include easy fatigubility, numbness and tingling sensation in the limbs.

i had repeated sins infections since moving in with a friend with a cat.recently i felt 'hair' moving in my thoat. that was when i could tell i had a parasite. the dr. tried to say it was just another sinus infection. so, i purchaced paragone and took double doses of it while fasting, then some milk of magnesia to pass them thru. then took 2 stool samples and insisted the dr. have them examined. the 1st dr. said it was sinus. the 2nd dr. said i didn't have them before even looking. i had to be persistant. i took the medication prescribed[mabendazole]. i feel there is alot less 'hair' moving in my throat but i can still feel them.

where are they from? Where can you get these paracites? What part of the world?

guest

it is every where acually the only way to get it is if u eat meat that isnt fully cooked and is infected by the paracites.. even if its infected u can eat it.. the heat from when u cook the meat kills it so make sure its cooked fully.

chritine

that is not true. fully cooked pork can still infect a person. if u pet an infected animal, the eggs can make their way to the person..many different ways they can be transmitted.

well. it sounds like you have a serious problem. im sorry that you are experiencing sickness. you spelled diarrhea wrong. that irks me. but you should go to a doctor to get that checked out. not ask random people that you dont even know online. thats not to smart. theres alot of creeps out there that could tell you something completely bizzar to hurt you because, well, their creepers. the common sense thing to do would be to go to your family doctor and get it diagnosed. thats what i would do anyway. but have fun finding out what it is. sorry about this rude comment. it just annoys me how people would trust strangers to ask for help. BYE!

guest

Well, you spelled bazaar wrong. That irks me.

guest

Well, you spelled bizarre wrong too. That irks me more.

guest

Could it be that all of you are spelling brassiere wrong? I believe I am definitely the most irked.

guest

*" They're creepers...not their" I'm glad you know how to spell diarrhea, what an accomplishment!

guest

you all are stupid for arguing about dumb stuff... go to a dictionary if you want to learn how to spell a word, not fight about it on a freaking website. how old are we now? im 18 and i know this. thanks for ur time.. and please stop arguing over the computer although funny, very stupid and childish :]

guest

Thanks for the entertainment. I particularly like "brassiere". Even if that wasn't meant to be funny... it was!

I am worried that I may possibly have a tapeworm but I´m not sure. I am visiting a foreign country and have been eating all types of different foods. This last week I have been experienceing sickness. Symptoms of diarrhoea, fatigue, loss of appetite, dizzyness and fever. I only felt all of these symptoms for two days but I am still experiencing Diarrhoea and fatigue after a week. I took medicine to help control it but it didnt´help much. I have not witnessed any type of worm in my stool. I´m worried that it can possibly be a tapeworm. I´m freaked out at the thought of it. Any advise what this may possibly be?

guest

Yep. Definitely tapeworm.
