AIDS: Wow, schistosomiasis has been doing a lot lately, and it's resurrected in a lot of places where it has disappeared.
Schistosomiasis responds to AIDS: I am a big family with many brothers, although we usually live in different regions, but as long as the conditions are right, we will expand.
Schistosoma reverts to dengue fever: Schistosoma is a big bug for our virus, and his brothers are also a big bug, and I can't tell the difference.
Yellow fever reverts to dengue fever: I can't tell the difference, schistosomiasis and malaria parasites are both bugs, and for me they are both giants.
Plasmodium reverts to yellow fever: I am a protozoa, belonging to the kingdom Protists, the phylum Protozoa, much smaller than Schistosomiasis.
Schistosoma reverts to yellow fever: Schistosoma belongs to the animal kingdom, the phylum Platyzoa, and is much larger than single-celled protozoa.
Japanese encephalitis reverts schistosomiasis: pathogenicity has nothing to do with size, our virus is powerful.
Clonorchis sinensis reverts to Japanese encephalitis: Schistosoma eats human blood and ranks first in the list of the world's top ten bloodthirsty and terrifying animals.
Toxoplasma gondii replies to schistosomiasis: There are people who look down on our parasite brothers, and the autobiography of schistosomia is posted so that they can see how powerful you are.
Schistosomiasis: Here's my autobiography.
My name is Schistosomiasis, which belongs to the phylum Platyzoa, and lives parasitically.
My life has taken many forms.
From an egg, it develops into a larvae, a maternal larvae, a daughter larvae, a cercariae, a juvenile worm, and finally an adult.
My adult worm is cylindrical, about two millimeters long, dioecious.
My male is shorter than the female, and the male curls into a female groove, and the female lives in the female groove.
My life history is complex, including two generations, sexual and asexual, done within vertebrates and mollusks.
My whole life started with an egg, which developed into a larvae in the water.
The larvae invade the intermediate host, the snail, and develop into cercariae in the snail.
Cercariae escape from the snail and infect the terminal hosts of mammals, such as humans and animals.
I continue to develop into an adult worm in the body of the terminal host and lay eggs to enter the next cycle of life.
There are many brothers in the Schistosoma family, and there are five main species that parasitize humans: Japanese, Egyptian, Mansoni, Interpolation, and Mekong Schistosomiasis.
Among them, the first three are the most popular.
My brother of Schistosoma japosis is found in China, the Philippines, Indonesia and Japan.
The intermediate host is the snail, and the terminal host includes more than 40 species of mammals, including humans.
The adult epidermis is detailless, and the eggs are oval.
Adult worms prefer to parasitize the inferior mesenteric vein and portal vein.
The eggs are excreted in the feces, and those that are not excreted remain in the intestinal wall and liver of the host.
My brother of Schistosoma haematobium, found in Africa and the Middle East.
The intermediate host is the vesicular snail, and the terminal host is primates such as humans and monkeys.
The epidermis of adult worms is distinctly detailed, and the eggs are spindle-shaped.
Adult worms prefer to live in the bladder and pelvic venous plexus.
The eggs are excreted through the urine, and those that are not excreted remain in the host's genitourinary system.
My brother of Schistosoma mansoni is found in Africa, the Middle East, the Caribbean and Japan.
The intermediate host is a double umbilical snail, and the terminal host is primates such as humans and monkeys, as well as mice.
The adult epidermis is less detailed, and the eggs are long and oval.
Adult worms prefer to parasitize the superior mesenteric vein and portal vein.
The eggs are excreted in the feces, and those that are not excreted remain in the intestinal wall and liver of the host, as in the case of the Schistosoma japonicum brothers.
Having said all this, you may feel confused, but it can actually be summed up in one sentence: "There are many kinds of my schistosomal brothers".
There have been several exciting moments in my life.
One of them was that my cercariae escaped from the snail and entered the water, and when humans came into contact with the infected water, I took the opportunity to burrow into human skin, causing human cercarial dermatitis and fever.
In the process of infecting humans, cercariae, larvae, adults and eggs can all cause harm to the host, but the main source of disease is eggs.
My eggs are deposited in different parts of the host, causing an immune response from the host, causing inflammation and secondary fibrosis.
My Japanese, Schistosoma mansoni fraternity causes mucus, bloody stools, and liver damage to human hosts, and over time, human hosts become deformed with emaciated limbs and swollen bellies.
My brother of Schistosoma haematobium will make the human host urinate urgently, urinately frequently, and urinately bloody.
All of my schistosomal brethren can also cause lesions in other parts of the human host, such as the skin, lungs, and brain.
If a child is infected by me, it will affect its growth and development and become a dwarf.
Either way, the injury can be fatal.
While I'm running amok, humans are looking for ways to deal with me.
Clever humans began to massively wipe out my intermediate host, the freshwater snail.
Snails, blister snails, double umbilical snails......
These are the homes of my adorable larvae.
Humans kill a large number of freshwater snails with niclosamide.
As the number of snails decreases, so does my population, and the trend of rampaging among the people is curbed.
Humans also invented medicine to deal with me.
Praziquantel, I hate you!
However, even under the double pressure of spiro-reduced and praziquantel, I was able to find a way out.
With the globalization of humanity and the ability of my schistosomal brothers to spread across regions, I await the opportunity to spread again.
AIDS: Wow, schistosomes have two ways to reproduce.
Schistosoma replies AIDS: Well, asexual reproduction in mollusks, sexual reproduction in mammals.
AIDS Reverts Schistosomiasis: Cool!
Flu: Schistosomiasis' autobiography is a bit boring, and he doesn't even understand the history of his own epidemic in the world.
Schistosomiasis responds to the flu: I have killed countless people, as evidenced by poetry.
One
There are many green waters and green mountains in vain, and Hua Tuo is helpless.
Thousands of villages and Xuli people left arrows, and thousands of households sang songs.
Sitting on the ground and traveling 80,000 miles a day, surveying the sky and seeing a thousand rivers from afar.
The cowherd wants to ask about the plague, and the joys and sorrows are gone.
Second
There are thousands of willows in the spring breeze, and 600 million Shenzhou is full of Shunyao.
The red rain turns into waves at will, and the green mountains turn into bridges.
The silver hoe of the five mountains of the sky fell, and the earth shook the iron arm of the three rivers.
By asking the plague gentleman what he wanted, the paper boat burned brightly.
Flu: This is "Sending the Plague God".
Schistosomiasis replies to the flu: Well, I was terrible back then, I was the "plague god" of human beings.
Angiostrongyloides cantonensis replies to schistosomiasis: awesome! My larvae like to live in mollusks, such as Fushou snails, brown cloud agate snails, ring snails...... It's all my favorites.
Schistosoma replied to Angiostrongyloides: This is the same as me, my larvae also like to live in freshwater snails, but I like nail snails, vesicular snails, double umbilical snails, and I don't like Fushou snails, brown cloud agate snails, and ring snails, so our larvae are not common.
Angiostrongyloides cantonensis responds to schistosomiasis: My adult worms live in the pulmonary arteries.
Schistosoma replied to Angiostrongyloides: My adult worms live in veins, so our adult worms are not common.
Clonorchis sinensis replied to Angiostrongyloides: Small tubule, you are a worm of the phylum Chlorozoa, don't be close to the set of my phylum Platyphylum.
Angiostrongyloides cantonensis replied to Clonorchis sinensis: Everyone is a parasite, don't divide your door and my door, the two doors are one family.
