Echinococcosis or Hydatid cyst is a parasitic disease caused by an infection of tiny tapeworms (Image 1). This infection can be naturally transmitted between humans and other animals. It can be transmitted by digesting feces, contaminated meat or other products. It is considered one of the most significant groups of communicable diseases. There are three different types of echinococcosis which can affect both human and animals; but only two are most commonly seen in humans and animals. The two are cystic echinococcosis and alveolar echinococcosis. In this essay I am going to explain more about the Echinococcus in general, the two different types of echinococcosis, the symptoms they create, and how they each affect the body differently.
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, ...

S. pyogenes is a bacterium that permeates our society. Today it is commonly known as the cause of “Strep. throat,” or Streptococcal pharyngitis. Modern medicine has caused the eradication of most of its advanced infections, while this most common form of infection still thrives. It is very contagious, and pyogenes travels quickly through places where bacteria flourish, such as schools and health institutions. The body cannot fight this bacterium very well without help, and S. pyogenes was a common cause of death until the introduction of antibiotics in the twentieth century. It has a number of ways to subdue the immune system, but it is almost completely vulnerable to penicillin, even after decades of exposure. While generally no more than a nuisance, this bacterium continues to be an interesting topic of discussion. (6,3,2)
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.
Ever wonder what kind of parasites are in your water, or how they can enter in to your body to make you very sick? Well it is most definite that no on want to get sick. The information found in this paper was collected over the past month, either by going to the library or by accessing information off the Internet at home, almost every night. The point that will be given to you is a little in information about the infectious disease called Schistosomiasis. The points the main points will be the causative agents, symptoms, hosts, methods of transmission and history of the disease. So lets see what Schistosomiasis is.
When one speaks of transmittable diseases one does not often think that cystitis is one of the most prevalent. Cystitis effects both genders, the young, the old and can lead to complications that can do irreparable damage to the urinary tract. The purpose of this paper is to discuss the disease of cystitis and relate the specific virulence factors of Escherichia coli to the prevalence and symptoms of cystitis. This will be accomplished by defining the disease, its etiology and the causative agent. The mode of transmission and risk factors will be discussed as well, the pathogenesis, signs and symptoms will be explained. Finally dietary and nutritional implication along with treatment and prognosis will conclude this paper.
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.

In North Dakota and various other surrounding states have a very harsh climate compared to other places. Because of this, multicellular parasitic disease is an uncommon occurrence. Physicians in North Dakota and surrounding areas rarely if ever see and treat patients with parasitic diseases; however, it can happen and it is important to be informed about such diseases in order to better treat and inform patients. I myself was not informed about several parasites that can live in the area and would like to pass the knowledge onto my peers as well. The parasites I will focus on are Diphyllobothrium Latum and Fasciola Hepatica. In order to have a better understanding of the pathology of the two parasites, the following topics will need to be reviewed
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.
Chapter 6 of Diseases and Human Evolution discussed schistosomes, or parasitic worms. I didn’t know snails were a vector of these types of parasites. The most important evolutionary mechanism that stood out to me was that Schistosomiasis haematobium mostly infects children. Because high levels of the eggs become displaced, the parasite continues to cause havoc in the body, causing the bladder to be unable to contract and expand, and can ultimately cause bladder cancer. This is the evolutionary mechanism. Even though you are expected to have resistance to reinfection, even though you don’t experience any symptoms, the eggs and flukes continue to live in your body with the potential to cause problems years down the line. Dormancy as a whole is something many parasites share, and it is a mechanism that allows them to continue to reproduce and thrive.
