Abstract This paper will go into depth on the life-cycle of the Taenia saginata parasite in its host(s), commonly known as the beef tapeworm, including how the parasite is contracted, the pathophysiology of the disease once in the host, the epidemiology of the disease where and who it affects, the signs and symptoms of the host and if any, the medicines required to recover from this intestinal infection. Taenia saginata, commonly known as the Beef Tapeworm, is an intestinal parasite that resides in humans causing taeniasis. Taeniasis is an infection in humans with the adult tapeworm of Taenia saginata. Humans are the only definitive hosts for T. saginata. Infection occurs worldwide where beef in consumed and cattle are raised but is uncommon …show more content…
solium tapeworm eggs are ingested. For example, people with poor hygiene who have taeniasis- with or without symptoms, will shed tapeworm eggs in their feces and might accidently contaminate their environment. This can lead to transmission of cysticercosis to themselves or others. Cysticercosis is a parasitic tissue infection which infects the brain, muscle or other tissue and is a major cause of adult onset seizures in most low income countries. A person gets cysticercosis by swallowing eggs found in the feces of a person who has an intestinal tapeworm and people living in the same household with someone who has a tapeworm have a much higher risk of getting …show more content…
Stool specimens should be collected on three different days and examined in the lab for Taenia eggs using a microscope. Tapeworm eggs can be detected in the stool 2 to 3 months after the tapeworm infection is established. Most people with tapeworm infections have no symptoms or mild symptoms. Patients with T. saginata taeniasis often experience more symptoms that those with T. solium because the T. saginata tapeworm is larger in size than the T. solium. Tapeworms can cause digestive problems including abdominal pain, loss of appetite, weight loss and upset stomach. The most visible symptom of taeniasis is the active passing of tapeworm segments through the anus and in the feces. In rare cases, tapeworm segments become lodged in the appendix, or the bile and in the pancreatic ducts. Infection with T. solium tapeworms can result in human cysticercosis, which can be a very serious disease that can cause seizures and muscle or eye
Hypothesis about signs and symptoms: Symptoms: cramping, diarrhea, and dehydration. These symptoms were thought to be due to the disease withdrawing fluid from the blood and irritating the stomach and
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.
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.
rink blood there. Tapeworms are slightly divergent because instead of drinking blood from the intestines, they drink other fluids in each intestine. Each one of these worms can be treated by getting specific pills from the local vet. There is one other inside parasite that is a larger risk than the others, and that is the heartworm. Just like Mitral Valve Disease, heartworms clog the heart, and owners must get special pills as soon as possible.
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.
It only takes the parasite six to seven months to grow into adult worms. Administration, Animal and Veterinary 5.... ... middle of paper ... ... It is very important to give your pet their preventative exactly 30 days apart without skipping a dose as doing so can lead to a positive heartworm test.
Tourists enjoy visiting the mountains of Rwanda to admire the gorillas and encourage their safety; however, humans help put mountain gorillas at risk. In 1999, a team of researchers with the Journal of Parasitology noted roundworm parasites in the feces of mountain gorillas (Ferber, 2000). These parasites normally affect only humans through contaminated water. Early, in 1988, blood and tissue samples of several mountain gorillas indicated measles infection (Ferber, 2000).

Toxoplasmosis is an infection caused by the obligate intracellular parasite known as Toxoplasma gondii.1 It is estimated to be the leading cause of food-related deaths in the United States and it infects up to a third of the worldwide population. Incidence is highest in areas that are hot, humid and at a low elevation, all of which are characteristic of the southwestern US where the case patient, S.C., is from. 2,3 Cats are the common culprit as they become definitive hosts of the parasite after they eat infected prey such as birds, rodents, and various small animals. The life of Toxoplasma persists as it is passed on through cat feces carrying as much as 100 million parasites every day and for as long as 21 days after infection.1,2 It undergoes several life cycles beginning with shedding of the oocysts in cat feces which carries the infective sporozoites that are ultimately converted into tachyzoites capable of disseminating from the small intestine to other organs, most notably in the CNS where it is difficult to find.1,3 There are several routes of transmission: consumption of contaminated water and food (especially undercooked or unfrozen meats), ingestion of cat feces through daily activities such as emptying a litter box, working with contaminated soil, congenital (especially during the third trimester), blood transfusions, or organ transplantation.1 This is of particular concern since S.C. reports having three cats at home which are known hosts to Toxoplasma. Furthermore, he has recently consumed a cougar that was killed on his property adding to his exposure to feline animals. The patient also insists that he only eats fully cooked meats such as the ungulates he hunts for food. However, presence of a cougar in his area could possibly indicate that surrounding animals, including the ungulates that he hunts, may have been exposed to Toxoplasma through feline feces. Thus, it is difficult to dismiss infection of the animals as almost all edible parts of an animal can harbor viable parasites.1
Clinical Presentation: Presented through a 24 year-old male with an issue of intermittent epigastric and lower abdominal pain. On the basis on clinical examination, the male was diagnosed with Irritable bowel syndrome (IBS). He was then transferred to a primary clinic. There, his symptoms did not improved and he was finally transferred to the hospital he is in now. Here, the hospital performed a capsule endoscopy and identified the parasite “Ancylostoma duodenale” in the proximal jejunum. From there the case of refractory IBS was reported more precisely and hook worm at the second part of the small intestine (Jejunum). From there, the patient was prescribed albendazole for three days. Ten days after the drug was given, the patients symptoms finally began to lessen and the patient
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.
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, ...
The Lumbricus Terrestris is the scientific term for the common Earthworm, and is otherwise known in the United States as the Nightcrawler. Earning this name due their habit of not appearing above ground to eat until the dark hours of the day, these segmented worms made up of annuli have the ability to dig six and a half feet deep into the soil. They commonly become seven to eight centimeters in length, and spend a lot of their time eating using their mouth which is located in the first segment of their body. ("National Geographic Common,") This first segment is the one located closest to the clitellum, which is the thick ring like band that demonstrates a worm is mature in growth. These worms move by taking full advantage of their small
Most human infections are obtained from either eating of tissue cysts in infected meat, products made by meat or by drinking water contaminated with sporulated oocysts that come from the environment or contact with cat fecal matter. The number of cysts found in skeletal muscles varies widely among different animals many of which are not all animals that are used for human consumption. It is also important to understand that seropositivity (The presence of antibodies or other immune markers that show prior contact to a specific organism or antigen (McGraw-Hill, 2002)) of animals that become meat may not show the risk these animals present for those that eat them. An example is with the meat of cattle and buffalo which rarely contain tissue cysts, however in some locations more than 90% of these creatures are seropositive for T. gondii. By contrast, seropositive pigs, sheep and goats have large quantities of tissue cysts in their meat (Tenter et al. 2000., Jones J.L., Dubey J.P., 2008). Pigs that have acquired Toxoplasma gondii are considered a significant source of infection for humans in the U.S. (Dubey, 1994). It is difficult to avoid exposure of pigs to T. gondii, therefore vaccination is considered to be an easy method for control. Vaccination with non-persistent strains of T. gondii is one of the approaches that has been used to reduce the prevalence of viable T. gondii in pig tissues (Dubey et al. 1998). Results from this study in 1998 showed pigs vaccinated with irradiated oocysts developed a protective immunity against clinical toxoplasmosis. The pigs that were vaccinated remained clinically normal whereas non-vaccinated pigs developed severe toxoplasmosis after being inoculated with a high dose of oocysts (Dubey et al. 1998). It seems that antibodies play a role in the ability of the body to have immunity however the mechanism of immunity brought on by feeding
