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.

Trichinella Research Paper
There are different species of trichinella that can cause human disease, which has much disturbance worldwide. There are several species of trichinella that have been discovered. They include T. pseudospiralis (mammals and birds worldwide), T. nelsoni (African predators and scavengers), T. native (Artic bears), and T. britovi (carnivores of western Asia and Europe) (CDC, 2012). In the United States, there are less cases reported now than in the past. In the 1940’s, the United States Public Health Services began tracking the number of trichinellosis cases. There were 400 cases in the United States each year on average (CDC, 1997-2001). From 2008 to 2010, 20 cases were reported each year on average (CDC, 2012).

Conclusions and Future Studies
Researchers from the Animal Parasitic Laboratory and Agriculture Research Service of the United States Department of Agriculture concluded that the linage of Trichinella spiralis originated from Europe over several thousand years ago (Rosenthal, LaRosa, Zarlenga, Dumans, Chunyu, Mingyuan & Pozio, 2008). This is the approximate time when pigs were first domesticated in that region. This implies that the species Trichinella spiralis was introduced to the Americas from pigs. However, there is evidence that the early people of this world, hominid hunters, have consumed foodborne parasites by hunting wild game from millions of years before. Today, swine is governed on the ensuing transmission, and evolutionary diversification.
He introduces the book with the concept of parasites and their role in balancing human population growth and their rise in the food chain or how he puts it “compensatory adjustments by other forms of life hemmed in human communities in such a tough and complex way that even after fully human skills had been achieved, the new efficiency attainable through cultural evolution was not sufficient to overpower and revolutionize the ecological system within which humanity evolved.” Interestingly McNeill gives agency to viruses and even distinguishes them as a safety measure preventing humanity from destroying the ecological balance of the world. Throughout Plagues and Peoples, McNeill tracks migration patterns, new points of contact, and warfare across countries and continents and how epidemic outbreak patterns correspond with major events.
This extremely pathogenic zoonotic virus is now understood to travel from bat species, to equine intermediate hosts, to humans.[8, 10] The Hendra virus is listed as a Bio-Safety Level (BSL)-4, and can only be studied at a few adequately equipped laboratories worldwide due to its virulence.[1, 2] Case fatality rates

In 1347, Europe began to perceive what the Plague had in store. Terrible outcomes arose when the citizens caught the Plague from fleas. The transfer of fleas to humans caused the outbreak of the Black Death. Infections that rodents caught were passed on to fleas, which would find a host to bite, spreading the terrible disease (“Plague the Black Death” n.pag.). When Genoese ships arrived back to Europe from China, with dead sailors and...
Abstract: Salmonella is a bacterium that causes one of the most common intestinal infections in the United States - Salmonellosis. The chance of contracting this disease is significantly high, and more and more people are suffering from the symptoms and complications of Salmonella. This paper will discuss about the disease itself, the current outbreaks that are related to this disease, preventions and the treatments.
Mosquitoes carried the diseases and when a person got bit he would give a disease to the mosquito and the mosquito would pass it on to the next victim ("Historical Overview").
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.
Salmonella is a gram-negative rod, which is known to infect humans, birds, and other mammals by invading and irritating the intestines. It is more common in poultry and swine which, if consumed, can cause diarrhea, nausea, vomiting, and stomach cramps. The infectious disease can be found almost everywhere and anywhere, including in water, animal feces, raw poultry, and raw seafood. Animals consume salmonella from the soil or contaminated processed feed. In humans, salmonella can lead to a developing typhoid-like fever that persists among other symptoms. However, there is no vaccine available for Salmonella but no treatment is needed because the infection is usually simply fought off by the immune system. There are various ways of preventing the salmonella infection as well, for example, careful cleaning of hands and utensils while cooking are simple preventative actions. Keeping clean and properly preparing food are the best ways contamination and spread of Salmonella can be avoided.
Exotic animals carry diseases and infections that can be potentially harmful or fatal to humans, jeopardizing the safety of the community. These diseases range in severity from common ringworm infections from African pygmy hedgehogs to lyssaviruses in p...
Salmonella is one danger that has caused many effects to consumers. Walsh writes about one incident when an outbreak “from tainted peanuts that killed at least eight people and sickened 600,” (Walsh 167). This incident left many people asking the same question, how can we trust the food that we put into our bodies? Salmonella, a type of food poisoning caused by bacteria found on different food types has caused an epidemic because of its domino effect on food and our health. Once one factory is contaminated, that factory could be housing both crops and meat, which is then transferred to our supermarkets and on our dinner tables. ...

You can also get salmonella poisoning from meat. People think that the problems come from eating red meat and are opting for fish over steak, but new evidence proves that fish can cause health problems too, risks that can’t be cooked away. This is a growing problem called histamine poisoning (Peck). Children are learning at a younger age that they don’t like meat, maybe because they don’t like the taste, or maybe it’s because they have a fear of eating their favorite cartoon or movie hero. For example, the pig from the movie “babe”.
Salmonella is also a bacterium that is widespread in the intestines of birds, reptiles, and mammals. It can spread to the human species a variety of different ways; through foods or animal origins. Some examples of food involved in outbreaks are eggs, poultry and other meats, raw milk and chocolate. The illnesses it causes are typically fever, diarrhea, and abdominal cramps. In people with poor underlying health or weakened immune...
Animal bites on humans may cause open wounds or even crushing injuries. Like us, all animals carry certain bacteria or viruses that can cause illness if passed on to humans via the open wounds. The pathogen entry pathway for these zoonotic infections include bites or scratches, and direct contact saliva or waste. These diseases bring about a considerable amount of inconvenience to humans and therefore, the greatest concerns are of young children and immunocompromised patients. Children are especially susceptible to getting bitten and an adult supervision is always recommended because their immune systems are still weak and an infection that might mildly infect an adult can be fatal for them.
