Freshly passed stool is the preferred specimen for isolation of nontyphoidal Salmonella species. Because stool carriage of Salmonella Typhi may be prolonged, the interpretation of positive results merits caution, and the diagnosis should be established only when accompanied by clinical findings that are typical of infection.

Although the prevalence of Salmonella infections is highest in children, salmonellosis outbreaks are common among individuals who are institutionalized and residents of nursing homes. The incubation period depends on the host and the inoculum is generally 6-72 hours.

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 recommendations are that antibiotics be reserved for patients with severe disease or patients who are at a high risk for invasive disease.
