Caused by bacteria in the genus Shigella, which are Gram-negative rod shaped bacteria. Symptoms start in 1 - 7 days; last 6 - 10 days and include diarrhea, abdominal pain, and bloody stools. The disease is more common in areas with unsanitary conditions.

Caused by C. jujuni, which is a Gram-negative spiral shaped bacteria with long flagellum. It is found in all chickens and 60% of cattle feces. Symptoms: Fever, cramping, watery diarrhea and abdominal pain.

This is generally a mild foodborne disease that is associated with undercooked meats and other foods. It is caused by the bacteria C. perfringens, which is a gram-positive, rod-shaped, endospore-forming anaerobic bacterium that is tolerant of high and low temperatures. Endospores will germinate rapidly in foods or within the intestine. The bacteria produces an enterotoxin that causes cramps and diarrhea. A severe form, called pig-bel or enteritis necroticans, causes hemorrhaging, pain, vomiting, and bloating.

Caused by a bacterium in the genus Vibrio, which is a curved Gram-negative rod containing one flagellum. Transmission occurs primarily by drinking water or eating food that has been contaminated by the feces of an infected person. Symptoms are due to the production of an enterotoxin and consist of the classic "rice stools" (mucous, epithelium & bacteria), violent vomiting and diarrhea. Loss of water and electrolytes causes shock, collapse, and possible death. The blood becomes viscous and organs may shut down.

This is an infection of a protozoan parasite from the genus Cryptosporidium, which causes the following signs and symptoms: Watery Diarrhea, stomach cramps or pain, dehydration, nausea, vomiting, fever, weight loss, lack of appetite, or the person can be asymptomatic. Symptoms may last anywhere from 1 to 2 weeks and may come and go during this time period. Spread person to person after the parasite releases its oocytes into the environment. Oocytes can be found in soil, food, and water.

This is an acute viral infection that affects infants and small children cause by the Enterovirus, coxsackievirus A16. The virus it typically spread by fecal-oral, oral-oral, of direct contact. Symptoms initially include fever, sore throat, and decreased appetite. After a couple of days painful sores may develop in the back of the mouth. Skin rash on the palms of the hands and soles of the feet may also appear.

This disease is the most common parasitic roundworm infestation in the United States affecting as many as one-third of American children; usually found in children between 5 and 10 years old. The causative agent is the nematode Enterobius vermicularis. Many are asymptomatic, but you may suspect infection if you notice frequent itching of the anal area, restless sleep due to etching and discomfort of the anal area, pain, rash, or other skin irritation because of itching, presence of the nematode in the area of the anus when they emerge at night to lay their eggs or presence of worms in their stools.

This disease is an inflammation of the gums caused by the bacteria Streptococcus sanguis 1, which is a gram-positive, facultative anaerobe that is a normal inhabitant in a healthy human mouth, particularly found in dental plaque. Signs and symptoms include swollen gums, bright red or purple gums, gums that are tender or painful to touch, bleeding gums or bleeding after brushing and/or flossing, and bad breath.

First described outbreak occurred in 1982, due to eating E. coli contaminated hamburgers from fast food chains. The E. coli strain O157:H7 has been responsible for several recent outbreaks and these strains of E. coli are capable of causing epidemics. Symptoms: Severe bloody diarrhea, severe abdominal cramps, mild fever, hemolytic-uremic syndrome (renal failure), and is life threatening (fatal in children 3%- 5%).

This infection of the digestive system is caused by G. intestinalis (also named G. lamblia), a microscopic parasitic protozoan. The parasite is transmitted by the fecal-oral route after eating contaminated food or drinking contaminated water. It is the most common small intestinal protozoan infection and is found worldwide. Signs and symptoms may vary and can last for 1 to 2 weeks or longer. Acute symptoms include diarrhea, gas, greasy stools that tend to float, stomach or abdominal cramps, and dehydration.

This disease is a viral infection that affects the salivary glands that's easily preventable by the MMR vaccine. Signs and symptoms include fatigue, body aches, headache, loss of appetite. and low-grade fever. The disease is transmitted by droplet spread or by direct contact.

Caused by the bacterium Helicobacter pylori. H. pylori was discovered in the lining of stomachs in 1982 through gastric biopsies. H. pylori is the main cause of stomach ulcers and chronic gastritis and a major cause of stomach cancers.

This is a viral infection of the intestinal track that is widespread in children, especially in day-care centers caused by a virus in the family Reoviridae. The virus is spread through the fecal-oral route and can be controlled by proper hand washing, but vaccination is the best way to prevent this infection. Signs and symptoms include severe watery diarrhea, fever, vomiting, & abdominal pain.

This is an inflammation of the large intestine caused by the bacteria Clostridium difficile. It is usually caused by antibiotic therapy that alters the normal flora of the large intestine that then allows C. difficile to grow out of control. Symptoms include abdominal pain, fever, diarrhea, bloating, and blood in the stool.

Caused by a virus that infects the liver. The virus is transmitted by the fecal-oral route from contaminated food or water. Symptoms appear 2 to 6 weeks after initial exposure and include fatigue, fever, abdominal pain, jaundice, and weight loss.

A viral intestinal infection that causes watery diarrhea, abdominal cramps, nausea, vomiting, and sometimes fever. Also known as gastroenteritis.

There are several types of viruses that can cause this illness. They include Noroviruses, Rotavirus, Adenovirus, and Astrovirus.

Caused by the flatworms Taenia saginata or Taenia solium from the class cestoda. They are an intestinal parasite that can be transmitted to humans by ingesting the eggs. These parasites commonly infect pork or beef. There are often no symptoms of an infestation. You may see signs of nausea, muscle weakness, diarrhea, weight loss, and the passing of worm sections in stool.

Caused by the single celled Protozoan parasite T. gondii. The parasite can be acquired by eating meat and drinking water contaminated with T. gondii, and can also be contacted through cat feces that contain the parasite. T. gondii can cause serious health problems to the developing fetus within pregnant mothers.

Caused by a bacteria in the genus Salmonella, which invades intestinal wall, passes through lymphatic system and then into the bloodstream where it is transported to many tissues. Symptoms: Fever, weakness, loss of mental alertness. Recovery appears fast but many pts shed bacteria for weeks.
