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 is it an ongoing sporadic infection among critically ill patients or than a point source spread (PubMed).

In Australia it is found in Culicoides biting midge (PubMed) so maybe insects are 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/Sulfa pending susceptibility testing.

One study suggests lower mortality with quinolones (PubMed).
