CSF: Elizabethkingia (Chryseobacterium) species  – Shipped May 13, 2019 –

MAIN EDUCATIONAL POINTS from M191-5

  1. 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.
  2. Elizabethkingia spp. are intrinsically resistant to cephalosporins and carbapenems. Antimicrobial testing is essential to determine therapeutic options, which are often limited.
