Patients will develop symptoms 10 to 48 hours after eating contaminated food. They may have a wide range of symptoms ranging from mild gastroenteritis to a severe diarrheal illness with dehydration and profound infection. Treatment Patients get better spontaneously, and antibiotics may even prolong the illness. Patients who are extremely ill or are at risk of developing disseminated infection, are treated with antibiotics. Typhoid fever is becoming rare in the United States.
Immunization is useful.
Treatment requires powerful antibiotics and specific treatments for other organ involvements. Staphylococcus Aureus Staphylococcus Aureus is probably the second most common cause of bacterial food poisoning in the United States. Infection occurs when food is prepared by persons who are asymptomatic but infected with particular strains of the staphylococcus. The bacteria multiply in the food and produce the toxin. The toxin that is produced by the food is not inactivated by heating.
