Before you continue to learn about this parasite, I hope you will first take care of Tintin with the warm palm of your hand, because the fish is nicknamed "Tintin Vampire"... They live in freshwater environments in South America and usually rely on sucking blood from gills that burrow into other fish, and these small fish have long gill lids with long spines that protrude backwards, and can continue to move in the host by twisting their bodies after burrowing into the bodies of other fish.
To confirm the host's location in turbid waters, the sensory tentacles of these parasitic catfish can sniff the fishy smell contained in the water flowing from the gills by the host. When a person urinates in the river, a stronger taste will attract this small catfish "upstream" and drill into tintin from the urethra...
The sharp pain from barbs and blood sucking was just the beginning of a nightmare, and in order to remove the small vampire fish parasitic in Tintin, doctors developed a slender mechanical device using traditional abortion equipment. The fork is equipped with a miniature camera that follows the urethra straight to the affected area, using a small but sturdy pair of pliers to remove the parasitic catfish from tintin. But before the wound heals, every time you boo, it feels like you're peeing on the barbs of these fish...
Filaria
The mere bite of a mosquito can spread this parasite, and when it invades the lymphatic system, it can gradually cause a large edema of the lower tissue of the skin, which is commonly known as "elephantiasis". In human hosts, adult filariae live in relatively fixed subcutaneous tissues, usually at the ends of the limbs.
A single mating between a male and a female can give birth to thousands of larvae entering the circulatory system, waiting for the mosquito to suck blood and then transfer to a new host. Happily, humans have found a cure for this parasite, and with the help of drugs, the immune system in the human body can kill the filaria like this.
Spinosaurus nematodes
The parasites are between 11 and 54 mm long, and their heads have a large number of epidermal spines that surround a bird-like beaked mouthpart. Scientists believe that the spinosa saccephalus originated in Southeast Asia, but they can be found all over the world, and once raw meat is eaten, any mammal can be infected.
In the early stages of infection, the host will also experience abdominal pain, fever, vomiting, loss of appetite, etc., at which point the larvae of the parasite are burrowing through the intestinal wall and entering the abdominal cavity. When it swims to the subcutaneous tissue, it can cause constant pain and itching, accompanied by severe edema and rash. After 1 to 4 weeks, the parasite can enter most areas of the body, eventually triggering meningitis or other lesions of the central nervous system.
Human skin fly (wild fly)
Listening to its name, you know that it is a crazy guy, there are several kinds of flies that lay eggs in mammals and hatch larvae (that is, maggots) are called mad flies, and there is only one known wild fly (human skin fly) that specifically incubates their maggot babies in the human body. The female of this wild fly attaches the eggs to the body under the wings, and the egg laying process is very simple, just airdropping on the skin.
Once hatched, the maggots quickly bite through the epidermis into the subcutaneous tissue and bite through the sharp mouthparts into tunnels several centimeters deep. In the human body, it can move the body using barbs on the surface of the body, and even extend the head beyond the skin for breathing every once in a while.
The only treatment is to force it out or stick it out, otherwise it will have to wait until the baby maggot crawls out of the body on its own.
Schizocephalic larvae
The target host of the parasite is a number of carnivorous mammals, the intermediate host is a frog or snake living in a water area with the larvae, humans only accidentally become a host after eating the schizophrenia host to cook incomplete meat, the earliest case was found in China in 1882.
In addition to eroding the eyeballs, this parasite can parasitize almost any part of the body after entering the human body, such as the pleura, tintin and the mysterious small garden... Fatal parasites such as the brain and spinal cord, in which the initial symptoms are directly hemiplegia. The picture above is of the larvae of Schizocephalus found on the wall layer of the pleura using thoracoscopy.
Giardia
Under an electron microscope, large patches of Giardia are covered on the mucous membranes of the host ... Scientists have found a total of about 40 species of Giardia in mammals, birds, and fish, which may be one of the most successful parasites on the planet. Humans can become infected when they drink, accidentally eat water, feces, food containing larvae, or come into unprotected mucosal contact with other hosts.
This is the ileum of a giardiasis patient, and the white plaque in the photo is caused by the multiplying giardia. After infection, patients will experience severe diarrhea, nausea, abdominal convulsions, and flatulence on day 2. Sometimes the body's immune system can destroy these parasites on its own, which takes about 2 to 6 weeks.
But without complementary drug therapy, symptoms may disappear after this time, entering a symbiotic phase of host and parasite, Giardia will attach a large area to the intestinal mucosa, hindering normal nutrient absorption, and in severe cases the host will die of extreme dehydration and starvation.
Wearing skin flea
This type of fleas is the worst jumping ability of all fleas, probably only jumping 20 centimeters high, because the female skin-piercing submersible flea has a large abdomen and can hold thousands of eggs. As for the way eggs are laid... Even if it is directly squirted through the hole in the epidermis, the female piercing flea will also die on the spot because of this rough way of laying eggs.
Male skin-piercing flea will leave the host after sucking blood and mating, but the female will bite through the host's epidermis into the subcutaneous tissue, and secrete a large number of chemicals during the parasitic stage, forming a spherical scaly tissue to protect the "nest" created by the female in the host's subcutaneous tissue.
After laying eggs, the female fleas, which are only 1 mm long, leave their bodies to decay in the subcutaneous tissues of the host, causing pit-like infected wounds on the skin. Since adult larvae are accustomed to continuing to root around the mother's carcass, these wounds are usually not far apart.
Here we will not attach a photo of the patient's wound after removing the skin-piercing flea, you should have seen the hive...
