Guinea Worm
This disease may be on the brink of being eradicated entirely but that doesn’t stop it from being one of the grossest things that anyone has ever seen. The parasite enters the body via unsafe drinking water. When people drink water infected with water fleas that have have been hosting the larvae of the parasite. There are no symptoms, to begin with, but about one year later, blisters on the feet or legs begin to develop and then the adult fully developed worm crawls out of the host body over a period of a few weeks. It’s said that the pain is intense and can incapacitate a person for weeks at a time. The pain can also continue for months after the infection. The parasite needs to infect a person at least once a year in order to continue. There were an estimated 3.5 million cases in 1986 but the disease has been greatly reduced over time and only 22 cases were reported in 2015. This disease will probably be the first parasitic disease to be completely eradicated in humans.
Filariasis
This disgusting worm parasite is spread by flies and mosquitoes. The adult worm spreads its larvae throughout the host’s lymphatic system and causes the lymph nodes to become clogged up. This also makes the tissue in the host’s body to swell up and create massive muscle deformations, otherwise known as elephantiasis. The elephantiasis mainly affects the legs and genitals. The disease also affects the eyes but that can be easily detected through close inspection but it commonly causes river blindness in the host. It’s been estimated that the parasite is one of the leading causes of blindness throughout the world.

Leishmaniasis
This parasite is spread through the bite of sandflies. There are three different types of infections and they each show varying degrees of severity. The cutaneous form produces mild skin ulcers, mucocutaneous produces ulcers in the mouth and nose, and the visceral form of the disease starts with skin ulcers and then fever, low red blood cell count, and an enlarged spleen and liver. The parasite is detected by a microscope and visceral can also be found by doing blood tests. 12 million people are in infected in 98 different countries and 2 million new cases are found every year. The disease also kills around 20 to 50 thousand people a year.
The meningeal worm is also known as the brain worm, or the deer worm. It frequently infects llamas and alpacas, but can infect other species as well like moose, elk, goats, and sheep. The meningeal worm is an internal parasite that is a part of the protostrongylidae family with the definitive host being the common white tailed deer. Even though they are the host, adult meningeal worms rarely cause clinical signs of disease in the deer. The white tail deer’s tolerance to infection from these worms is actually beneficial to the parasite because the white tail deer are the only species that will allow the worm to complete their life cycle.
the definition of parasite, is something that hurts. for ever. this parasite, was a landmine. I had good medical attention. But once i returned home, I finally left. I wanted to leave. there were rockets, raining down in every place i looked. those rockets stole my family. we couldn't stay. so we fled. the last time i had a true education, was when i entered high school. between 2nd grade and 9th the education i had in my birth place, that wasn't any kind of education. i wanted more. and there was nothing there for me to want
Schistosomiasis is a parasite. This parasite is a worm that you get through contaminated water. Urine and feces usually contaminate the water. The worm goes in to your body and migrates to the bladder, rectum, liver, lungs, spleen, intestines and some veins. After the worm migrates to these places this is where it matures and lays its eggs. The disease has the ability to lay two thousand to three thousand eggs per day and can live for twenty years. There are five different kind of Schistosomiasis that effect humans, these different kinds are; S. mansoni, S. Heamatobium, S. japonicum, S. intercalatum and S. mekongi. There are also other kinds of Schistosomiasis that occasionally infect humans, there are; S. bovis, S. mathei, and some avian schistosomes.
The most common way this disease is transmitted from one animal to the next is through mosquitoes. A mosquito carrying infective heartworm larvae bites a dog and transmits the infection to them. The larvae grow, develop, and migrate in the body over a period of 6 to 7 months, in which time they become sexually mature male and female worms. this is the prepatent period. The worms then reside in the heart, lungs, and associated blood vessels. The worms begin to mate and release microfilaria into the blood stream. When a mosquito bites an infected dog it takes in some of the microfilaria in the blood. After 10 to 30 days there is larvae in the mosquito’s salivary gland which can then be passed on to the next dog the mosquito bites.
I learned about this ecological disaster while reading my newest edition (October 2001) of Maxim. As I was flipping through my new magazine I saw a horrifying picture of a fish; it looked as though something took a bite out of its neck. Interested, I continued to read, “The Coming Plague” by Jeff Wise. Basically, Maxim exposes the entire path of this deadly modern-day epidemic starting in 1987, when a veterinary graduate student at
It is caused by parasites of the Plasmodium species(in text reference). These parasites are carried by mosquitoes which become infected after biting someone who has malaria. Malaria is then passed on to others when the infected mosquito bites another person. In rare cases malaria can be passed to another person through blood transfusions, organ donations or shared needles.
Once your dog is infected with the parasitic worm the mosquito bites the next dog and the cycle continues. (Administration, Animal and Veterinary)
Malaria is spread when the mosquito picks up the parasites from the blood of an infected human when it feeds. The mosquito will first recieve the malaria parasite from feeding on the blood of a person who may not neccessarily show symptoms of the disease, but has the parasites in their bloodstream. When the mosquito feeds again, these parasites will be passed on to another human being. Symptoms of malaria include fever, shivering, pain in the joints, headache, repeated vomiting, generalized convulsions, and coma. If not treated, the disease, especially that caused by protozoa falciparum, will progress to severe malaria. Severe malaria generally results in death.
When the adult female worm is ready to emerge, she creates a blister on the skin anywhere on the body, but usually on the legs and feet. This blister causes a very painful burning feeling and it bursts within 24-72 hours. Immersing the affected body part into water helps relieve the pain. It also causes the Guinea worm to come out of the wound and release a milky white liquid into the water that contains millions of immature larvae. This contaminates the water supply and starts the cycle over again. For several days, the female worm can release more larvae whenever it comes in contact with
a Silly Fly. This quote particularly talks about a wasp being caught in the web, or the trap, of a spider.
This paper includes an understanding about the parasitic roundworm called trichinella. It gives detail of the disease, its transmission and source. Emphasizing how it effects the body, further explaining the epidemiology and how the parasite poses a threat. Also providing an overview of the various types of transmission, how it obscures the human body, and informs one about the symptoms that occurs with the ingestion of trichinella. This paper also addresses the various diagnostic procedures and the treatment required in order to treat Trichinellosis. This, emerging the complex world of the most common type of trichinella species called Trichinella spiralis. In addition, it raises awareness of the health risks and possible outcomes that can come along when the parasites begins migrating throughout the body.
A little boy, a husband, and a marathon runner suffer from parasites in their immune systems. Parasites are organisms that live in or on a host. Steve and Laury’s 9 year old son Chris gets infected by a parasite. His temperature rose to 110 fahrenheit. At one point his eyes started to roll back. Seizures started to occur frequently. The doctors revelead that after an MRI he had encephalitis.It causes inflimation to the affected area but inflamation in the brain can be very dangerous. Steroids were used as a testing to see if it was possible for him to get better. Acanthamoeba was tested positive on his body. It enters the body through the nose or skin travels to the brain and feeds of cells.
Approximately half way through the third instar the larvae must being preparation for the pupariation stage where the larvae will make the transition from larvae to blowfly. To do this they stop feeding on the body and begin to move away in search of a dark, cool area and are often found to have buried themselves within soil (if present) reaching approximately 2cm-3cm down. This is commonly known as the post feeding and wandering stage of the third instar. Depending on the environment of the crime scene some of these larvae have been found up to 30 meters away from the body in an attempt to find a suitable
Well in the spring all the males and young winged queens leave their nest and fly high in the air and mate. The few ant queens that survive this “marriage flight” cast off their wings and instinctively begin to look for a spot to start a new ant colony. After making a nest, the young queen ant seals off the entrance and begins to lay eggs. Some of the first batch are eaten by the queen for nourishment. When the surviving eggs hatch, they become like larvae. After a few weeks each larva spins a cocoon around itself and pupates.
A year ago, a companionship of missionaries met a young farmer and patient whom they named “Robert”. He had been suffering from the disease for almost a year then since he and his fellow farmers were infected. According to his story, they all worked in a particular rice field in Palo, Leyte which was already reported to have a high number of infected residents. Sadly, his co-workers died of the disease. Likewise, in Basa, Trento, Agusan del Sur in Mindanao, 70% of the residents were infected with the disease. Award-winning Filipino documentary “Alaga” by Kara David exposed public awareness of a tremendous number of people who acquired the disease and used Basa as the basis of the report. In the said video, David witnessed how possible it was for most of the residents to have a similar disease. She met a certain family, Bandera, where all members except the infant are hosts for the parasites. One of her daughters died in 2007 of the same disease. Malou, the mother, said that they were infected when they came in contact with the water around them. The river that surrounds the place serves as their source of drinking water, a place where they wash clothes and a playground for their children. According to the data gathered by the city health office from snail specimens that lived in the waters of Basa, the place where they play, wash and
