DefinitionSalmonella enterocolitis is an infection in the lining of the small intestine caused by Salmonella bacteria.Alternative NamesSalmonellosis; Nontyphoidal salmonellaCauses, incidence, and risk factorsSalmonella infection is one of the most common types of food poisoning. It occurs when you swallow food or water that contains the salmonella bacteria.The salmonella germs may get into the food you eat (called contamination) in several ways.You are more likely to get this type of infection if you have:Eaten foods such as turkey, turkey dressing, chicken, or eggs that have not been cooked well or stored properlyFamily members with recent salmonella infectionBeen or worked in a hospital, nursing home, or other long-term health facilityA pet iguana or other lizards, turtles, or snakes (reptiles are carriers of salmonella)A weakened immune systemRegularly used medicines that block acid production in the stomachCrohns disease or ulcerative colitisUsed antibiotics in the recent pastMostpeople with this conditionare younger than 20.SymptomsThe time between infection and symptoms is 8 – 48 hours. Symptoms include:Abdominal pain, cramping, or tendernessChillsDiarrheaFeverMuscle painNauseaVomitingSigns and testsThehealth care providerwill perform a physical exam. You may have signs of a tender abdomen and tiny pink spots on the skin called rose spots.Tests that may be done include:Blood cultureComplete blood count with differentialFebrile/cold agglutinins (test for specific antibodies)Stool culture for salmonellaTreatmentThe goal is to make you feel better and avoid dehydration. Dehydration means your body does not have as much water and fluids as it should.These things may help you feel better if you have diarrhea:advertisementDrink 8 to 10 glasses of clear fluids every day. Water is best.Drink at least 1 cup of liquid every time you have a loose bowel movement.Eat small meals throughout the day, instead of three big meals.Eat some salty foods, such as pretzels, soup, and sports drinks.Eat some high-potassium foods, such as bananas, potatoes without the skin, and watered-down fruit juices.Give your child fluids for the first 4 to 6 hours. At first, try 1 ounce (2 tablespoons) of fluid every 30 to 60 minutes.Infants should continue to breastfeed and receiveelectrolyte replacement solutions as recommended by your health care provider.You can use an over-the-counter drink, such as Pedialyte or Infalyte. Do not water down these drinks.You can also try Pedialyte popsicles.Watered-down fruit juice or broth may also help.Medicines that slow down diarrhea are usually not given because they maymake the infection last longer. If you have severe symptoms, your health care provider may prescribe antibiotics.If you take water pills ordiuretics, you may need to stop taking them when you have diarrhea. Ask your health care provider.Expectations (prognosis)In otherwise healthy people, symptoms should go away in 2 – 5 days, but they may lastfor 1 – 2 weeks.The bacteria can be shed in the feces of some treated patients for months to a year after the infection. Food handlers who carry salmonella in their body can pass the infection to the people who eat their food.Calling your health care providerCall your health care provider if:There is blood or pus in your stoolsYou have diarrhea and are unable to drink fluids due to nausea or vomitingYou have a fever above 101F or your child has a fever above 100.4F, along with diarrheaYou have signs of dehydration (thirst, dizziness, light-headedness)You have recently traveled to a foreign country and developed diarrheaYour diarrhea does not get better in 5 days (2 days for an infant or child), or it gets worseYour child has been vomiting for more than 12 hours (in a newborn under 3 monthsyou should call as soon as vomiting or diarrhea beginYour child has reduced urine output, sunken eyes, sticky or dry mouth, or no tears when cryingPreventionLearning how to prevent food poisoning can reduce the risk of this infection.Proper food handling and storage can help reduce the risk. Good hand washing when handling eggs, poultry, and other foods is important.If you own a reptile, wear gloves when handling the animal or its feces because salmonella can easily pass to humans.ReferencesDuPont HL.
