MAIN EDUCATIONAL POINTS from M191-5
- Elizabethkingia spp. are rare but important causes of critical infections in immunocompromised hosts, including neonates. They can cause septicemia and meningitis, and less commonly, line infections and pneumonia.
- Elizabethkingia spp. are intrinsically resistant to cephalosporins and carbapenems. Antimicrobial testing is essential to determine therapeutic options, which are often limited.
