Herbaspirillum

Microbiology

gram-negative. Can be mistaken for Burkholderia cepacia.

Epidemiologic Risks

"Most species of Herbaspirillum are nitrogen-fixing bacteria that are commonly found in the rhizosphere and colonize plants endophytically. They are found in the roots and stems of maize, rice, beans, bananas, sugar cane, pineapple, and other plants and they have been recovered from groundwater and drinking water distribution systems as well (PubMed)." Man. Can you imagine getting infected for the rhizosphere?

Syndromes

Bacteremia usually in hematologic malignancies. Patients resond to treatment but I can't help but wonder what happens to any broken nitrogen.

Treatment

Who knows. Susceptible to ceftazadime, levofloxacin, minocycline, moxifloxacin, ticarcillin/clavulanate, tigecycline, and trimethoprim/sulfamethoxazole.
