IV. Symptoms

  1. Abdominal cramps
  2. Diarrhea
  3. Fever (>71% of cases)

VIII. Management: Antibiotics

  1. Not indicated in uncomplicated non-typhi Salmonella Diarrhea
  2. Indications
    1. Severe infection or hospitalized
    2. Bacteremia or Sepsis
    3. Dysentary (inflammatory Diarrhea)
    4. Disseminated disease (treat for 4-6 weeks)
    5. Age <12 months or >50 years

    7. Valvular heart disease
    8. Severe Coronary Artery Disease
    9. Malignancy
    10. Uremia
    11. Liver disease
    12. Sickle Cell Anemia
    13. HIV or AIDS
    14. Immunocompromised (treat for 14 days)
  3. Precaution: Growing Antibiotic Resistance
    1. Third generation Cephalosporin resistance increasing
    2. Fluoroquinolone resistance increasing (especially in Asia)
    3. Hohmann (2001) Clin Infect Dis 32:263-9 [PubMed]
  4. Antibiotic course
    1. Typical duration: 7-10 days
    2. Immunocompromised: 14 days
  5. Adults with severe disease
    1. Infection not acquired in Asia
      1. Ciprofloxacin 500 mg twice daily OR
      2. Levofloxacin 500 mg once orally daily
    2. Infection acquired in Asia (Fluoroquinolone resistance)
      1. Azithromycin 500 mg orally daily OR
      2. Ceftriaxone 2 g IV every 24 hours (or Cefotaxime 2 g IV every 8 hours)
    3. Other alternatives
      1. Carbapenem (e.g. Imipenem)
      2. Trimethoprim-sulfamethoxazole (TMP-SMZ) 160/800 mg twice daily for 5-7 days
        1. Higher resistance rates
  6. Children with severe disease
    1. Ceftriaxone every 24 hours (or Cefotaxime every 8 hours)
    2. Azithromycin
    3. Carbapenem (e.g. Imipenem)
    4. Trimethoprim-sulfamethoxazole 8-10 mg/kg/day of TMP component divided twice daily
      1. Higher resistance rates

IX. Course

  1. Onset: 6 to 24 hours (up to 48 hours)
  2. Duration: 4 to 7 days (untreated)
  3. Infectious: Asymptomatic shedding for 3-4 weeks

Ontology: Salmonella (C0036111)

Definition (NCI_CDISC) Any bacteria that is not assigned to the species level but can be assigned to the Salmonella genus level.
Definition (NCI) A genus of motile, rod-shaped Gram-negative enterobacteria in the phylum Proteobacteria.
Definition (MSH) A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.
Definition (CSP) genus of gram negative, facultatively anaerobic, rod shaped bacteria that utilizes citrate as a sole carbon source; it is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia; food poisoning is the most common clinical manifestation; organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.

Ontology: Salmonella food poisoning (C0036114)

Definition (MSHCZE) Otrava způsobená požitím potravy infikované různými druhy salmonel. Podmínky pro chov, přepravu, porážku a marketing domácích zvířat přispívají k rozšíření této bakterie.
Definition (MSH) Poisoning caused by ingestion of food harboring species of SALMONELLA. Conditions of raising, shipping, slaughtering, and marketing of domestic animals contribute to the spread of this bacterium in the food supply.
