Microbiology
Gram-negative rod, A. radiobacter, now R. radiobacter (I LOVED OK Computer) is a common cause of disease in humans as is Rhizobium pusense (Pubmed).
"The genus Agrobacterium is quite heterogeneous. Recent taxonomic studies have reclassified all of the Agrobacterium species into new genera, such as Ahrensia, Pseudorhodobacter, Ruegeria, and Stappia, but most species have been controversially reclassified as Rhizobium species.(Pubmed)."
Epidemiologic Risks
They are common in dirt and plants and cause plant tumors. If your patient is a vegetable, that doesn't count.
Syndromes
A hodgepodge of case reports. Many are vascular/catheter infections in immunoincompetent hosts.
One "Munchausen syndrome, which was confirmed when we discovered self-injection of feces and dirt into a central intravenous (IV) line.(Pubmed)."
Treatment
Variable susceptibility, third-generation cephalosporins, and their moral equivalent should suffice.
