Tell me something about the life cycle of a liver fluke?

Liver filukes are Digenetic Trematode. Generally three types of trematodes are there. Monogenetic trematode (Monogenea) which have a simple life cycle and are parasitic to fishes. Digeneans hav a complicated life history involving on or more intermediate host. The third one is a Cestode which have a still more complicated life history.Both Digeneans and Cestode are parasitic to a wide spectrum of hosts fishes upto mammals. \nRegarding the life cycle of a liver fluke --- they are hermaphrodites but often go for maing. The have well developed copulatory structures. They produce thousands o0f eggs. These eggs hatch in water form miracidia. miracidia will search for a smnail, They are specific to snails also. inside the snails they will become redia and finally emerges with a tail called cercaria. Cercaria is free swimming form. after fingding a suitable palce where it can go to the definte host ( If it is a cow then on grasses, if it is a bird then on fishes some time directly penetrate into the body like blood flukes Schizostomia in human being) this stage is metacercaria nad they live from days to years depending on the intermediate hopst and the species and then inside thae adult they form the liver fluke. The sheep liver fluke fingd its way through snails and then grasses. If you can put snails in a petri dish with little water and observe daily you will find lot of cercaria emerges from them and free swimming in water.\nEggs- Miracidia (free swimming in water)- snail (reddia) - emerges agin as cercaria (free swimming) settle as metacercaria in plants and goes in to the intestine with grasses and goes to the liver and settles there.

I found a primary article talking about Cyanobacterial blooms causing liver cancer in China. It is mentioned in the first paragraph of the main body. Hope this helps!

yes!!!!!!!!!!!!!! you need to look at a site on the liver and stones ,,,,,this is where stones start at then whenthe liver is full  of stones  they then go to the gall bladder are you familiar with liver flushes i got out 1000 stones out of my liver  yeal i did say 1000 stones ,, heard about this several years back when i was very ill did a parasite cleanse thena liver flush and no.....................more troubles     why have a knife after you when there are natural ways  ck it out  go to liver flushs.com  many sites on this natural way  god bless hope you find the anwser,

This is a long story so hold on and bear with me OK?\nThe lancet fluke (Dicrocoelium lanceolatum) belongs to the order Trematoda. Like other flukes, scientifically called trematodes, it as well shows a generation cycle with a change of reproduction as well as a change of hosts. The terminal host are mammals, usually sheep or goats. The distribute the fluke's eggs by their excrements on plants, on which snails feed. Those snails again are the intermediate host. . \nThose snails, mostly hygromiid snails of the species Helicella or enid snails (Zebrina), take in the flukes eggs together with their food. In the snail's digestive gland the fluke' first larval generation hatches. That generation is called miracidium. A miracidium is a simply built larva with few resemblance to the adult fluke. It is able to swim or at least to float by a ciliar crest. The miracidium makes a metamorphosis inside the snail, resulting in the next larval stage, that more resembles the adult fluke. The so called cercary has got a tail that propels it in the water. The cercaries change themselves in endurance stages called cystes, that the snails surrounds with a mucus layer and excretes them.\nRed ant (Formica rufa). Source: Manfred Eidelloth.   \nAnts eat those mucus balls (obviously the mucus contains also certain pheromones that makes it highly attractive to ants) and then are afflicted by the cercaries. The cercaries grow in the ants' abdomen (terminal body part) and then one of them moves into the head. There they afflict the ant's nervous system and cause a change of behaviour, that makes Bernard Werber *) call them "zombie ants". The ants now, very untypically, climb up plant stems and attach themselves with their mandibles to exposed positions such as leaves. Grazing mammals, such as sheep or goats, eat the plants together with the ants and then infect themselves with the lesser liver fluke. Inside this terminal host the cercaries change into the fluke's adult stage which reproduces sexually and then lays eggs that are excreted by the mammal -  the generation cycle is closed when the next snail eats the eggs.

Some experts feel that up to 95% of the North American population has at least one or more types of parasites living in their bodies. Authorities claim that we have more parasitic infections than some third world countries, and that Africa has less of a problem then we do!\n\nParasites release toxic wastes that are actually their feces and urine.  Parasites urine is practically pure ammonia.  Parasite waste can affect the kidneys, liver and immune system.\n\nHow do we get parasites?  If an estimated 95% of North American's have parasites, they must be very easy to get!  The primary way is from our food and water (over 50% of it is infected).  Organic food, often grown with animal manure, may be a greater source of parasites than commercial food.\n\nThe eggs of parasites are microscopic and are the real danger.  They can be passed sexually, as well as through shaking hands, walking barefoot, eating or drinking from someone else's glass, bottle, can, fork, etc.  Parasites can also be passed through swimming in polluted lakes, rivers, streams or even by going to the beach.\n\nWe can get parasites from our pets.  Anyone who is sick or has a health problem should try to remember when it started and when he or she got the pet.  You may find it was around the same time.  Every time that your pet licks it's anus, they are possibly putting thousands of parasites on their tongues.  When they lick you, those eggs are going right on you!  The link between a sick child and a new puppy is seldom realized.\n\nADVICE: There are two immediate goals for dealing with parasites. First, get rid of them as swiftly and safely as possible. Don't try to speed up their dismissal. Second, stay free of them. They are prone to return.\n\nP.S. (after your added comment) Please remember that most doctors in this country are not very informed on the issue of parasites. Once a diagnosis is made, your doctor will prescribe either drugs, such as Flagyl (metronidazole), which causes severe side effects--nausea and headaches--in about half of those who take it, or a natural regimen to irradicate parasites.

if your keeping one as a pet they'll eat crickets, wax worms, and meal worms, although you dont want to give them wax worms more than twice a week b/c they have a lot of fat in them, and if you give them meal worms you have to crush the heads first b/c the meal worms hard outershell meens its still alive in the frogs stomache and can chew at or through the stomach lining.  i immagen silk worms would also be good if you could get a hold of them

Porcine Ascarias\n\n \n\n\n\nAscaris suum, commonly known as roundworm, is the largest gastrointestinal parasite of the pig. From a respiratory disease standpoint, roundworms are important because part of their life cycle involves migration of the immature larvae through the lungs of the pig. This larval migration can result in large areas of the lung parenchymal tissue being damaged, with subsequent development of aerobic or anaerobic bacterial infections. As larvae migrate through the lungs, they destroy alveoli; they may cause a local eosinophilic infiltration that sometimes manifests in allergic reactions; and they cause a non-productive cough referred to as "thumps" or "thumping," also known as verminous pneumonia. \n\nBacterial super-infections may also occur, resulting in edema and emphysema, along with a tremendous cellular reaction. Mycoplasmal pneumonia is also not an uncommon sequel to a severe case of ascariasis.

the worms are actually larvae -- they are pre-pubesent incects like flies.  the flies lay their eggs in food -- chances are you have eaten a billion fly eggs in food and never knew it.  anyway back to the story -- when the food gets the right mositure it signals the eggs hatch out larvae that live off the decomposing food  and they get big and fat and round.

The life cycle of Iodamoeba bütschlii involves trophozoites that live in the host's large intestine and cysts that are passed in the host's feces.  Humans are infected by ingesting cysts, most often in food or water contaminated with human fecal material.  This species is considered to be a commensal (non-pathogenic).  Nevertheless, it is important to differentiate this species from the pathogenic Entamoeba histolytica since it would be inappropriate to treat a person if they were not infected with a potential pathogen.\nI. bütschlii is found in pigs as well as humans, and the infection can be transmitted from pigs to humans.  Thus, the presence of this organism is of concern since it would indicate that the infected person might be infected with other organisms that are transmitted via food or water contaminated with fecal material.\n\nThis trophozoite of this species can be differentiated from Entamoeba histolytica and Entamoeba coli based on its appearance of its nucleus (a large endosome with little chromatin on the nuclear membrane).  The cysts of I. bütschlii characteristically contain a large glycogen vacuole that makes it easy to distinguish from other species.
