Effects of Guinea worm disease
Don’t take our word for it - see why 10 million students trust us with their essay needs.
I. Introduction A. Attention Step: Can you imagine living each day with little to no water. Not even enough water for a toilet or a shower. While reading my textbook for my nutrition class, I came across this horrific picture that disturbed me to the core. It prompted me to want to know more about what this all means. (PICTURE) B. Establish Credibility: According to the CDC, it is estimated that 801,000 children under the age of 5, around the globe, die from diarrhea each year. Most deaths occur in developing countries without access to adequate clean water. This equals nearly 2,200 children that are dying every day because of diarrheal diseases from contaminated water. In Flint, Michigan there are 9,000 children with …show more content…
Sub-point 1 Guinea worm disease People become infected with Guinea worm by drinking water from ponds and other stagnant water containing tiny "water fleas" that carry the Guinea worm larvae. The larvae are eaten by the water fleas that live in these water sources. Once drunk, the larvae are released from copepods in the stomach and penetrate the digestive track, passing into the body cavity. During the next 10-14 months, the female larvae grow into full-size adults. These adults grow up to 3 feet long and as wide as a cooked spaghetti noodle. 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
In reproduction, the female produces clusters of eggs that she carries in one or two egg sacs that are attached to her abdomen. Once hatched, The T. Californium’ life cycle has quite a few stages. The first being six naupliar (young) stages lasting 4 – 10 days. Next come the 6-copepodite stages (7-14 days for the first 5 stages) ending in the last stage where T.californicus is a sexually mature adult. Adults then live from 40 – 90 days after the stages are complete (Rickets and Calvin 1985).
Infestation of up to 20 meningeal worms has been discovered in a single deer’s subdural cavity. The white tail deer is the preferred host, but they rarely ever suffer from any sickly or neurological problems from this type of worm. We will see severe signs in llamas and alpacas; these are the two animals that can become infected with it frequently. The meningeal worm can cause damage to the central nervous system and could result in death so it is important to try and catch it early and learn about how to prevent this deadly worm. Things that you should be familiar with about the meningeal worm are its life cycle, the signs in your animal, and any prevention or treatment options.
Sabellaria cementarium belongs to the phylum Annelids and is an invertebrate polychaete species. They are found in small clumps at the rocky bottoms of the sea floor where they use the rich source of natural phytoplankton as their primary diet (Qian and Chia, 1990). The tube-like worms can behave social and form extensive reefs or independently build hollow tubes in to the sandstone (pawlik and Chia, 1991). Embryos form a polar lobe that is absorbed in to the blastomeres at the end of division. Larval development and movement follows shortly after the 14-15 hour fertilization period where spiral cleaving of the fertilized oocytes appears (Render, 1983). Much is still not known about the invertebrate worm in their natural niche.
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.
Unique Fact: Humans cannot contract the amoeba from another person or by drinking contaminated water. The amoeba enters your body through your nose, by contaminated water and voyages to the brain through the nerves that transmit the sense of smell.
Today I am going to be choosing diabetes for my medical topic. There are several types of diabetes. There is type 1 diabetes, type 2 diabetes and gestastional diabetes. Our body naturally produce insulin and but sometimes there are cases where are body doesn’t produce enough insulin or does not properly respond to the insulin produced which results in high blood sugar levels. High blood sugar levels is not healthy for our bodies because it can lead to us going into a coma. If this is left untreated it can cause very serious health problems including death.
Living in the world that consists of three thousand different types of mosquitoes is frightening. People got used to a daily routine of waking up and getting to their jobs, that many of them are so focused on their career and family that they do not even notice and pay much attention when they are getting bitten by mosquitoes. Unfortunately not many people were aware of the fact that not all insects are safe, many of mosquitoes transfer infections, but we were not concentrating on that since it was considered not a common issue. As a repercussion, people did not begin to react and notice that something wrong with them when Aedes mosquitoes began their attempt on ruining people’s social, physical and psychological lives by transferring a Zika virus to the once who are bitten.
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.
Cholera is a water-borne disease caused by the spreading of toxins throughout the intestines by the Vibrio Cholerae bacterium. Bad hygiene and other unsanitary conditions such as contamination of food and water can result in this unpleasant infection. As stated in the Gale Encyclopedia of Medicine, “contamination starts when a person infected with cholera steps into a community water supply.” Cholera is more common in places with poor cleanliness and insufficient water treatment. These locations include environments consisting of brackish rivers and coastal waters such as an underdeveloped country like Africa. Cholera can affect anyone but is usually targeted at younger ch...
Topic: Addiction to social media General Purpose: To persuade Specific purpose: To persuade my audience that social media is hurting us mentally and our social lives. Thesis: Social media can cause serious problems to you and your health, so we need to put addiction to social media to rest. I. Introduction A. Attention-getter: The ages of 55 and 64 year olds who use social media fell “worried or uncomfortable” when they can’t access any type of social media accounts (Wright, 2015).
Factors that support the growth and distribution of these parasitic worms include warm and moist climate, poor sanitation and Hygiene, and compromised water supply control systems.

Although preventive measures can be taken, over 21.5 million people annually become infected with Typhoid fever. In particular, areas with poor sanitation of water report higher rates of this disease. Typhoid fever is spread through contaminated water sources, making underdeveloped countries vulnerable to the infection.
The cestodes, or better known as tapeworms are a class of parasitic flatworms, classified under phylum platyhelminthes. There are three major species of tapeworms: taenia saginata (beef tapeworm), taenia solium (pork tapeworm) and diphyllobothriasis (fish tapeworm). All these species of tapeworms are acquired by humans in consumption of raw, undercooked or smoke contaminated meat or fish (John, 2006). Tapeworms are considered humanity’s largest intestinal inhabitant. They each have a scolex or head, that attaches to the intestinal wall. As long as the head remains attached to the intestinal mucosa, a new worm can grow from it. Tapeworms do not contain a digestive tract, so their nourishment comes from absorbing partially digested substances from the host. They are whitish in color, flat and ribbon like, with a covering that resembles a transparent skin like layer (Turkington,2007). It’s prevalent among underdeveloped countries where sanitation is poor and among people who regularly consume raw, unwashed or undercooked beef, pork or fish containing the cyst eggs of various tapeworms (John, 2006). But in the United States, laws governing feeding practices and inspection of domestic food animals have largely eliminated the problem of tapeworm, but an estimated 1,000 new cases are diagnosed in the United States each year (askville, 2013). There are two specific parasites that I will be discussing. One being the adult tapeworm that inhabits the small intestine and cysticercosis which is the most common parasitic disease of the central nervous system, also called neurocysticercosis.
In skin tissues the larvae mature into adults, which commonly exist in nodules in skin connective tissues
