None - What Is Being Tested?
The stool culture is a test that detects and identifies bacteria that cause infections of the lower digestive tract. The test distinguishes between the types of bacteria that cause disease (pathogenic) and the types that are normally found in the digestive tract (normal flora). The test helps to determine if pathogenic bacteria are the cause of a person's gastrointestinal symptoms (gastroenteritis). The bacteria found in stool are representative of the bacteria that are present in the digestive system (gastrointestinal tract). Certain bacteria and fungi called normal flora inhabit everyone's gastrointestinal tract. They play an important role in the digestion of food and their presence keeps a check on the growth of disease-causing bacteria. Sometimes, the balance of the normal flora may be affected by the administration of broad-spectrum antibiotics; the drugs inhibit the growth of normal flora and allow the bacteria Clostridium difficile that is resistant to the antibiotics to survive and overgrow the digestive tract, leading to symptoms such as diarrhea and abdominal pain. Pathogenic bacteria can enter and infect the digestive tract when someone eats food or drinks water that is contaminated. Examples of contaminated sources include raw or undercooked eggs, poultry or beef, unpasteurized milk, and untreated water from lakes, streams, and (occasionally) from community water supplies. (For more on this, see the article Food and Waterborne Illness.) People who travel outside the U.S., especially to developing nations, may face a greater risk of being exposed to disease-causing bacteria. Some of these bacteria may be true pathogens while others are strains of gastrointestinal bacteria that are normal flora for the local inhabitants but cause gastrointestinal distress to the tourist. Visitors may become infected by eating or drinking anything that has been contaminated with the bacteria, even things as simple as tap water, ice cubes in a drink, a fresh salad, or - How Is It Used?

A stool culture may be ordered when someone has signs and symptoms of an infection of the digestive tract, such as: Diarrhea that lasts more than a few days and may contain blood and/or mucus Abdominal pain and cramping Nausea, vomiting Fever Not everyone who has these symptoms will necessarily have testing done or be treated. In people who have healthy immune systems, these infections often resolve with supportive care and without the use of antibiotics. A stool culture is more likely to be ordered when a person: Has severe symptoms, dehydration, electrolyte imbalance, and/or other complications Is very young, elderly, or has a weakened immune system; according to the Centers for Disease Control and Prevention (CDC), diarrhea is a global killer. It is the second leading cause of death in children under the age of 5 worldwide, killing an estimated 2,195 children a day. Has prolonged signs and symptoms and/or infections that do not resolve without treatment Has an illness during and following travel outside the U.S., especially to emerging nations; the CDC estimates that 30% to 70% of those who travel outside of the U.S. will get a GI infection. Has eaten food or drunk fluids that may have been contaminated with pathogenic bacteria, such as undercooked meat or raw eggs, or the same food that has made others ill Is ill and a possible foodborne or waterborne outbreak prompts the medical community to investigate and identify the cause; examples include contaminated produce, contaminated food from a specific restaurant, and/or illness on a cruise ship. A healthcare practitioner may order one or more stool cultures when someone has had a previous pathogenic bacterial infection of the gastrointestinal tract and has either been treated for it or it has resolved on its own. This may be done to verify that the pathogenic bacteria are no longer detectable because in some cases people can become carriers of the bacteria. Carriers are - What Does The Test Result Mean?
If a stool culture is positive for pathogenic bacteria, then they are the most likely cause of the person's diarrhea and other symptoms. Results are frequently reported out with the name of the pathogenic bacteria that was detected. Some of the most common pathogenic bacteria that cause infections in the U.S. and their most frequently encountered sources include: Campylobacter – found in raw or undercooked poultry and unpasteurized milk; it is one of the most common causes of bacterial diarrhea in the U.S. It may become especially serious if it spreads to the blood, and it occasionally causes long-term complications such as arthritis and Guillain-Barré syndrome. Salmonella – found in raw eggs (even intact disinfected eggs), raw poultry, uncooked vegetables, and in reptiles; pets such as lizards and turtles may carry salmonella in their intestines without being ill themselves. Some humans may become carriers of salmonella. Salmonella may be transmitted person-to-person. Shigella – found in food and water contaminated with stool and from infected person-to-person when careful sanitation is not observed; for instance, it can be a challenge to prevent the spread of Shigella within a family and in a daycare or nursing home setting since very few organisms may cause disease. A wide variety of other bacteria may sometimes cause GI infections and may be identified with a stool culture. Some important examples include: Escherichia coli 0157:H7 and other toxin-producing E. coli (most strains of E. coli are considered normal flora and do not cause disease) – found in raw or undercooked hamburger/beef, spinach, or unpasteurized cider; causes bloody diarrhea and may lead to hemolytic uremic syndrome. Clostridium difficile – may be present as part of the normal flora, but use of broad-spectrum antibiotics can result in an overgrowth of these bacteria. Toxin-producing strains can cause diarrhea and other serious complications. If these strains are suspected - Is There Anything Else I Should Known?
Severe pathogenic bacterial infections of the gastrointestinal tract and those causing complications may be treated with antibiotics, but many uncomplicated cases are best left untreated. People with healthy immune systems will usually get better on their own within a week or so. They are instructed in how to prevent the spread of the infection and are treated and monitored for symptoms such as dehydration. Pathogenic bacterial infections are monitored on a community and sometimes national level. Other than foreign travel-related cases, health officials try to determine where an infection came from so that they can address any potential public health concerns. Bacterial isolates causing foodborne illness are sent to the State Public Health Laboratories to be typed by molecular methods. The results of the typing are uploaded into a national database to detect common source outbreaks across the U.S. The typing helps to identify specific foods or food products that are the source of the infection. Travelers' diarrhea is typically caused by toxin-producing Escherichia coli, which are the leading cause of bacterial diarrhea infections among travelers to Africa, Asia, and Latin America. These strains of E. coli, however, are different than the strains of Shiga toxin-producing E. coli (O157:H7), which can cause hemolytic uremic syndrome.
