Elizabethkingia meningoseptica


Gram-negative nonfermenting obligate aerobe.

Epidemiologic Risks

They are found in the environment, especially water including hospital water.

There has been an on going issue with outbreaks in Illinois that is an ongoing sporadic infection among critically ill patients rather than a point source issue (PubMed).

In Australia it is found in Culicoides biting midge(PubMed) so maybe insects re the vector?

Elizabethkingia miricola is found in Asian Spotted Frogs (PubMed) and in the Mir space station. I am not certain what the two have in common.


Bacteremia, VAP, meningitis usually nosocomial.


Often multidrug resistant, perhaps piperacillin/tazobactam or TMP/Sulfapending susceptibility testing.

One study suggests lower mortality with quinolones (PubMed).
