Can snails in an aquarium be infected with schistosomiasis?

I have been raising straw tanks for more than 3 years, and I have also given birth to a lot of snails, and I haven't seen any insects, so I don't think I need to worry about cleaning up the snails when I'm fine.

Schistosoma parasitizes most vertebrates, and there are 6 species that parasitize humans. Only Japanese schistosomiasis, abbreviated as schistosomiasis, is endemic in China. Snails are the only intermediate host for Schistosoma japonicum.

The life history of Schistosoma japonicum is complex, including alternation of sexual generations within the terminal host and asexual generations within the intermediate host snail. The life cycle is divided into seven stages: insects, eggs, larvae, maternal cytes, daughter larvae, cercariae, and larvae.

A hairlarvae burrows into the body of the snail and reproduces asexually to produce tens of millions of cercariae, which mature in batches in the snail and escape one after another.

The water body containing eggs can hatch when the temperature is between 5 35, and 25 30 is the most suitable; The total process of cercariae formation takes temperature-dependent, with a minimum of 44 days and a maximum of 159 days. Mature cercariae escape from the snail and swim actively in the water. When cercariae or positive snails infected with schistosomiasis are present in the water body, it becomes infected water and is infective to humans and animals.

Although you have not been wild picked, there will be no snails in the aquarium without external input. Therefore, as a precautionary measure, it is recommended that you take steps to completely eliminate the host and eliminate that possibility in the first place.

The snail is a mollusk, divided into female and male, amphibious, composed of two parts, the front part of the soft body is the head, neck, foot and mantle, and the back part is the internal organs; Those who have longitudinal ribs on the surface are called"Ribbed shell snails", the shell is about 10 mm long and 4 mm wide, and it lives in lakes and marshes or water network areas; The shell surface is smooth"Smooth shell snails", slightly smaller than the rib shell snail, 6 mm long and 3 mm wide, respectively, is more common in hilly areas.

Snails are the main intermediate host of Schistosome.

SchistosomesSchistosoma is also known as schistosoma. Schistosomes live in most vertebrates, and the eggs pass through the walls of the veins into the bladder and are excreted in the urine. The larvae develop in the body of intermediate host snails, mainly Bulinus and Physopsis.

Mature larvae enter the body of the terminal host through ** or mouth. Schizodiac mansonii (S. mansoni).Mansoni (i.e., Schistosoma mansoni) is found in large and small intestinal veins, mainly in Africa and northern South America.

The eggs are excreted in the stool. The larvae enter the snail and then return to the terminal host body through **. Schizosoma japonicus (S. japonies)

Japonicum, i.e., Schistosoma japonicum) is mainly found in Chinese mainland, Japan, Taiwan, the East Indies, and the Philippines, and in addition to humans, it also infects other vertebrates such as domestic animals and rats.

Schistosoma parasitic in humans is different from other human parasitic trematodes in terms of morphology, physiology and life history, such as schistosomiasis is dioecious; Adult worms parasitize in the mesenteric veins or vein plexus of the bladder, and eggs are excreted in feces or urine, depending on the species; The tail of the cercariae is forked and invades the host through ** in the water; There are no thunderlarvae and cystic stages in the life history. Taking Schistosoma japonicum as an example, we will give a more detailed description and briefly introduce Schistosoma mansoni and Schistosoma haematii. Schistosomiasis, called "Gu" or "Water Gu" in ancient literature, is mostly infected by contact with infected water with schistosome larvae.

Sui Chao Yuanfang et al. "On the Origin and Syndrome of Diseases: Water Gu Syndrome" cloud: "This is caused by the accumulation of water and poisonous gas, which makes the abdomen gradually enlarge and ......Famous water Gu also. "After infection, fever, chills, cough, chest pain, etc. can be seen in the initial stage; Over time, it is characterized by hypochondriac lumps, distension and ascites, etc., and the consequences are more serious.

Heating, bleaching powder, iodine tincture and niclosamide have a killing effect.

Disadvantages It is recommended to change the water completely

Stop talking, I'm so scared of schistosomiasis drops.

Unless you drink the water, or eat the snails.

The one in Jiangsu? Are you sure it's a snail?

It's not the right concept. Snails are only one of the hosts of schistosomes, and not all snails carry schistosomes. It can be eliminated by cutting off the life history.

In fact, protein worms are harmless, and some fish (such as manlong, goldfish, and scavengers) will also use it as food. Your Arhat's death should have nothing to do with it, but something else.

The cause of this insect is that the water body is too fertilized, and if there is only a small amount, it can be left alone, but if there is too much, it will be removed.

It is best to change the water in the tank immediately, and be sure to pay attention to the temperature and water quality when changing the water for the fish. Wash the fish tank thoroughly with salt water, yellow powder, or gentamicin solution, and let the fish tank soak in salt water for a while.

Fish all the fish in a different tank or basin and soak the fish in brine or gentamicin for 5---10 minutes.

This kills a lot of parasites on the fish, and after soaking, the fish can be put back in the tank.

It may be that you feed too much and the fish can't finish eating, so the water is too rich in protein, so you should pay attention to feeding in the future. If it is a filter belt, replace the filter.

Suggestion: Strengthen the filtration system, use a magnetic brush first, change the water 1 3 (change the water in small quantities and many times later), wash the filter cotton frequently, wash the filter material with the water of the original tank, reduce feeding, barley worms, bread worms are not fed temporarily. Buy a larger scavenger, this is not possible.

As long as you don't eat it raw, it's fine, because schistosoma is very afraid of burning, and as long as the temperature exceeds 70 degrees, it will die.
