Revision as of 22:10, 13 September 2020

Background

Gram-negative bacillus
Acquired from unpasteurized milk, undercooked meat (especially pork), contaminated water
- Classic association with chitterlings

Clinical Manifestations

Incubation period of Usual incubation period:1 to 14 days
Gastroenteritis, often with pain isolated to right lower quadrant mimicking appendicitis
Concurrent pharyngitis in 20%, can can be isolated from throat swabs
Complications include hematogenous dissemination with metastatic abscesses in the liver and spleen, mesenteric adenitis, terminal ileitis, and pseudoappendicitis
Can lead to reactive arthritis and erythema nodosum

Management

Unclear if antimicrobial treatment is beneficial unless severe
Generally indicated in:
- Severe disease
- Extraintestinal disease, including meningitis, cellulitis, pneumonia, osteomyelitis, and endocarditis
- High risk populations, including the elderly, people with diabetes, people with cirrhosis, and immunocompromised patients
Options include ciprofloxacin, ceftriaxone, TMP-SMX, doxycycline, and aminoglycosides
