Uncommon Parasites Discovered In The Human Body

Uncommon Parasites Discovered In The Human Body

An organism is considered a parasite if it depends on its host to survive. We're not talking about a relative who is constantly in need of a loan or a favor—although that thought could cross your mind. such as worms and amoebas. A few different kinds of parasites can make people sick. Some settle inside of you, such as trichinella spiralis, a roundworm that typically infects people when they consume raw or undercooked pork and causes trichinosis. Others are outside pests, like a flea that feeds on your blood. Protozoa, helminths, and arthropods are the three main categories of parasites, whether they are found inside or outside of an organism. Single-celled parasitic protozoa are so tiny you must use a microscope to view them.

They frequently coexist in peace with us in our intestinal tract and enjoy eating bacteria and other germs. But some of them can spread disease, such the malaria-causing protozoa Plasmodium. The second type are helminths. These are parasitic worms that are a little larger than protozoa, like tapeworms and pinworms. The third group, arthropods, are not parasites in and of themselves, but they are frequently used as hosts for parasitic diseases. Warm temperatures, such as Southeast Asia or other tropic or sub-tropical regions of the world, are where parasite diseases are most common. Malaria, one of the most widespread parasite illnesses, kills an estimated 1 million people annually, largely in sub-Saharan Africa.

Although it is possible, the purpose of the parasites is typically not to kill the host; after all, the parasite needs that host to survive, so why deliberately sabotage a good thing? Although parasitic infections are still a concern, the picture in the United States differs slightly from that in tropical areas. Trichomoniasis, a sexually transmitted illness brought on by the protozoan trichomonas vaginalis, is the most prevalent parasite infection in the United States, with 7.4 million cases reported annually. The protozoan Giardia, which causes digestive issues, comes next and is responsible for an estimated 2 million infections annually. The third place finisher on the list is cryptosporidium, a protozoan that most frequently infects people when participating in recreational water activities and sports and results in 300,000 infections annually. But it's their uncommon equivalents, not these widespread parasites, that intrigue us. These individuals may not receive therapy. the ones that might prompt you to reconsider where you swim or how you prepare your meals. Introduce the parasite that causes the infection known as sparganosis, spargana, to start off this parasite party.


There are more than 2,000 different varieties of catfish, although most of them are not dangerous. aside from the candiru. It's okay to be afraid of the candiru. This little catfish, which is only 0.5 to 3 inches long but may become as long as 6 inches, is usually the subject of urban legends, but in this case, the story is actually factual. The parasite freshwater catfish known as candirus, which is found in the Amazon River, may be attracted to your orifices. they are all. I agree, even that one. Due to their keen sense of locating nitrogen, these fish prefer to establish themselves inside a host and feed on blood. Humans also excrete nitrogen, however we do so in the form of urine instead of the fish, which generally does so through its gills. Remember to use the restroom before swimming in the Amazon since candiru don't recognize the difference between a gill and a urethra. It will lessen the chance of a tiny catfish becoming stuck within your urethra.

Japanese Lung Fluke

A parasitic worm called a fluke, which most frequently infects people as paragonimus westermani and paragonimus kellicotti. Although it can infect other body areas, such the brain, it typically affects the lungs. the positive news The parasites that cause this ailment can only be found in crayfish and crabs. However, the P. kellicotti parasite is also found in crayfish in the American South and Midwest. The danger of contracting a lung fluke is highest in Japan, Korea, China, the Philippines, and Indonesia, as well as several regions of Africa and South America. The initial signs of lung fluke infection are typically chest pain, coughing, fever, diarrhea, and abdominal pain as the parasite moves from your stomach through your body and into your lungs. Many times, the symptoms can be mistaken for meningitis, bronchitis, or even tuberculosis. Lung flukes can develop to a length of between 0.3 and 0.5 inches, and like the parasites we've already discussed, they can remain inside a human host for up to 20 years.


What may grow up to 11.8 inches long and survive within your body for up to 20 years? What is ravenous for your brain and other tissues? lovely spargana. Sparganosis is a food-borne ailment that primarily affects animals other than humans and is an intestine infection brought on by the spargana parasite, a tapeworm. You only run the danger of contracting the disease if you consume raw meat from an infected bird, reptile, amphibian, or mammal, or if you drink contaminated water.

Depending on what area of your body the parasite inhabits, sparganosis symptoms might vary greatly. In certain places, you might not have any symptoms, but if it determines your brain looks comfortable, you might have headaches or seizures. Infections with sparganosis are most common in Thailand, China, Japan, Korea, and other Southeast Asian nations. Sparganosis is an uncommon condition. Between 1927 and 2007, 22 provinces in China reported a total of about 1,000 sparganosis illnesses. Furthermore, there were only 52 cases reported in Thailand during the course of the 67 years from 1943 to 2010 Human infection rates in the United States are still substantially lower than those in Thailand.

Naegleria Fowleri

A parasite amoeba that can be found in freshwater lakes, ponds, rivers, and hot springs is what causes naegleria infection. Only the Naegleria fowleri species infects people, and it does so by entering the body through the nose. Once inside, the amoeba produces primary amebic meningoencephalitis, which is an infection of the brain. The signs and symptoms of PAM can appear anywhere from a day to a week after the amoeba enters your body and frequently include headache, fever, nausea, vomiting, and stiff neck. In the US, getting PAM is extremely uncommon. Between 2001 and 2010, just 32 cases were documented in the United States.

Unfortunately, it is equally uncommon to survive the illness. Only 12 or so people have reportedly survived out of the 200 cases that have reportedly been documented across the globe. The infection spreads swiftly after symptoms appear, leading to additional issues like seizures, confusion, and hallucinations. Patients with the illness frequently pass away in less than two weeks, and occasionally in less than one week. By refraining from swimming or engaging in any other activities that need you to be around warm, untreated, or insufficiently treated waters, you can reduce your risk of contracting Naegleria fowleri.

Gnathostoma Spinigerum

Infections with gnathostomiasis are uncommon everywhere. Although they are now also observed in Central and South America, reports of them in Southeast Asia predominate. The Centers for Disease Control and Prevention classifies this illness as an emerging imported disease. This indicates that it is dispersing globally exactly as we do when we travel. You run the risk of contracting gnathostomiasis if you consume undercooked or raw infected foods such freshwater fish, crustaceans like shrimp, crab, and crayfish, frog meat, pork, and chicken. Gnathostoma spinigerum is a parasite that resembles a helminth.

Though this parasite can persist in your body for up to ten years after infection, humans aren't actually particularly excellent hosts for it. We are unintentional, unintentional hosts for this organism since they cannot proliferate in our bodies as they can in those of other hosts. You will benefit, but the parasite will suffer. Instead, they migrate throughout your body over their 10- to 12-year life cycle, inducing swelling under your skin.
