Pantoea agglomerans is a Gram-negative bacterium that belongs to the family Enterobacteriaceae.

Formerly called Enterobacter agglomerans or Erwinia herbicola, it is an ubiquitous bacterium commonly isolated from plant surfaces, seeds, fruit (e.g., mandarin oranges), and animal or human feces.

Pantoea agglomerans was occasionally reported to be an opportunistic pathogen in immunocompromised patients, causing wound, blood, and urinary-tract infections. However, using the biochemical panels commonly employed in medical diagnostics it is difficult to differentiate Pantoea agglomerans from other species of the same genus or from members of related families such as Enterobacter, Klebsiella, and Serratia spp.[1] It is thus not surprising that subsequent molecular studies based on DNA sequencing have disproved the identity of several clinical isolates initially reported as Pantoea agglomerans, thus questioning the effective hazardousness of the species.[2][3] For the precise identification of Pantoea agglomerans other methods such as Multilocus sequence typing (MLST) or Whole-Cell MALDI-TOF MS are therefore recommended.[4]

Pantoea agglomerans is found in the gut of locusts, which have adapted to use the guaiacol that Pantoea agglomerans produces to initiate swarming of locusts.[5]

It is also commonly found as a symbiont in the gut of mosquitoes, where it has been genetically engineered to produce antimalaria effector molecules, reducing the prevalence of Plasmodium by up to 98% [6]
