Diagnostic and Public Health Testing 1 Infection is diagnosed when a laboratory test detects Salmonella bacteria in stool, body tissue, or fluids. The test could be a culture that isolates the bacteria or a culture-independent diagnostic test (CIDT) that detects genetic material of the bacteria.#N#CDC encourages laboratories to culture specimens with positive CIDT results. This process is called “reflex culturing.” 2 Clinical diagnostic laboratories report the test results to the doctor and submit Salmonella isolates to state public health laboratories for serotyping and DNA fingerprinting. 3 Public health laboratories report the results to CDC’s Laboratory-based Enteric Disease Surveillance and to PulseNet. 4 Public health laboratories forward unusual serotypes to CDC’s National Salmonella Reference Laboratory for further characterization or confirmation.

Overview
- Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract. Salmonella bacteria typically live in animal and human intestines and are shed through feces. Humans become infected most frequently through contaminated water or food.Typically, people with salmonella infection have no symptoms. Others develop diarrhea, fever and abdomi…
Treatment
- Because salmonella infection can be dehydrating, treatment focuses on replacing fluids and electrolytes. Severe cases may require hospitalization and fluids delivered directly into a vein (intravenous). In addition, your doctor may recommend: 1. Anti-diarrheals. Medications such as loperamide (Imodium A-D) can help relieve cramping, but they may also prolong the diarrhea ass…
- Salmonella gastroenteritis is usually a self-limiting disease. Fluid and electrolyte replacement may be indicated in severe cases. Because antibiotics do not appear to shorten the duration of symptoms and may actually prolong the duration of convalescent carriage, they are not routinely used to treat uncomplicated nontyphoidal Salmonella gastroenteritis. Current recommendation…
- Typhoidal Salmonella typhi infections cause typhoid fever. Someone with typhoid fever will need to take antibiotics. It is important to take the full round of antibiotics and not stop just because you begin to feel betterthis disease is notorious for being passed to others after a person's symptoms decline. We will describe the symptoms and treatment for typhoid more completely l…
- Salmonella infections usually resolve in 5-7 days and often do not require treatment other than oral fluids. Persons with severe diarrhea may require rehydration with intravenous fluids. Antibiotics, such as ampicillin, trimethoprim-sulfamethoxazole, or ciprofloxacin, are not usually necessary unless the infection spreads from the intestines. Some Salmonella bacteria have bec…
Prevention
- You may reach for antibacterial soap to keep your family safe from harm. Killing more bacteria has got to keep them safer, right? Not necessarily, according to the Food and Drug Administration. The FDA says there is no evidence washing up with plain soap and water is any less effective at preventing illness. The vaccines are not 100% effective, though. If you are traveling to an area w…
