Tapeworms
What are tapeworms? Tapeworms are a parasite that can be caused by the consumption of food or water that has been contaminated by eggs or larvae. There are two types of infections the first is called an invasive infection which is caused by the ingestion of the eggs if they migrate outside of the intestines into the body tissues and organs. The other type is called an intestinal infection which will occur if a larva develops into an adult tapeworm in the intestines. The body of a full grown tapeworm consists of head, neck, and proglottids which are a chain of segments. The head of a tapeworm will stick to the wall of the intestines where the proglottids will grow and produce more eggs. The intestinal tapeworms are normally a mild concern, but the invasive infection can have a severe impact on the body if left untreated. These worms can be quite dangerous if left untreated.
How long could a creature like this survive? Well an adult tapeworm has the possibility to live up to thirty years in its host. This is a scary thought and some different factors that could increase risk for having to live with a problem like this are: poor hygiene, exposure to

Some of these are things like roundworms and pinworms. There have also been multiple different studies where a tapeworm was placed under a microscope to help understand their life cycles and bodies better. These studies have helped to find cures for the infections and to identify other parasite infections. Overall the main cause of this disease is having ingested the eggs of the parasite. This is the most well known cause for this disease. These parasites have been around for years now and occur in both humans and animals so they have a very clear idea of the symptoms from years of treatment and studying of the parasite, and it is now a common disease that is dealt with
ImageText BoxImageOne of the biggest threats to the environment of Ontario is the Gypsy Moth (Lymantria dispar dispar). The species itself is native to Europe and Asia. How this affects us is by weakening trees across Ontario and North America. The first time the gypsy moth was found in Ontario was 1969. The gypsy moth can be found in southern Canada (Ontario), New Brunswick, Nova Scotia and British Columbia. It is known to weaken trees and the caterpillar form live in trees and during most outbreaks its caterpillar feces would fall from the trees to the ground or even on top of humans. The average Gypsy Caterpillar can grow 5-6 centimeters long. With five pairs of blue spots and six pairs of bright red dots on their back. The female moth are white and can fly on the other hand, the male moth are brown and can also fly. The female have a 5cm wing span but male have a 2.5cm wing span. The gypsy moth usually lives in open forests and other forests and take up at least 20% of the space. The Gypsy moth are about 4cm long, tan coloured and can be located on tree trunks, furniture, and buildings. (OFAH Invading Species Awareness Program, 2012)
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. So alpacas and llamas are unsuitable hosts and that is why the meningeal worm is such a threat to them. It can cause varying degrees of damage to their central nervous system. “The cerebrospinal fluid tap is especially useful for diagnosing meningeal worm and ruling out other diseases.” (Whitehead, Bedenice 2009.) Ruling out other diseases helps to narrow down what could be ...
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
Oftentimes, people can recall at least one song they know that is undoubtedly catchy because of its repetitive nature. That song can become a nuisance, when it will not leave your mind. When a melody gets stuck in your head, sometimes it could take a whole day to forget the tune. A certain tune can be stuck in your brain for many years! In Oliver Sacks’ passage, “Brainworms, Sticky Music, and Catchy Tunes”, he talks about “earworms”, or a pathological repetition. Sacks uses patterns of development to inform the modern reader about the dark side of music.
Canine Heartworm Disease Canine Heartworm Disease is a serious and potentially fatal disease caused by the parasite Dirofilaria Immitis. The disease can infect over 30 species, including humans, however dogs are the definitive host. 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.
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.
Merriam-Webster defines ‘parasite’ as ‘an organism that lives in or on another organism and benefits by deriving nutrients at the host 's expense’.
The everyday death of man is a show for the angels. Our hero worm represents death and people are the actors. The worm of death is from the Phylum Nematoda. Many roundworms cause diseases in humans, which can lead to death. I have, however, reason to believe this is actually the blood fluke, Schistosoma of the Class Trematoda in Phylum Platyhelminthes.
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.
Worms. It's not something that most dog-owners want for their beloved pups; but unfortunately, it's something that happens all too often. Worms and other parasites aren't just disgusting to think about, they are also potentially dangerous. At the first suspicion—or sight—of worms, you should take action quickly, so that your family pet doesn't suffer from upset tummy, grumpy behavior, or death.

In order for you to understand how Echinococcus works. You have to understand how it is transmitted into your system and begins infecting you. Echinococcus goes through several different steps on how it is developed and then transmitted to other hosts. The adult echinococcus tapeworm is about 5 mm long and lives in the small intestines of dogs and another canine species such as coyotes, wolves and foxes. The stage where a cyst begins usually occurs in intermediate hosts; typically sheep’s but they can also affect cattle’s, horses, camels, pigs and goats and many others. Tapeworm eggs are passed by the feces of infected dogs and then are digested by grazing sheep’s. These eggs then hatch into the embryos within the intestines, and then penetrate the intestines to be carried by the blood to major organs such as the liver and lungs. This larval stage of the parasite is called an oncosphere. The larval stage spreads by the bloodstream to target organs and other parts of the body, such as liver, lungs, ...
If you had a choice between a burger and a bowl of crickets, I think I would know which you choose to eat. As disturbing as this sounds, in the near future we may not have that choice. With our annual protein consumption rising, and Europe’s protein sources decreasing, coupled with a growing population, we may have only one alternative… Insects.
