Severe Sepsis From Enterobacter

Despite the increased frequency of nosocomial infections due to Gram-negative bacteria, publications of infection from Enterobacter species are rare. Two serious illnesses were produced by this group of organisms; one involved a patient with endocarditis from E aerogenes, while the other was a case of suppurative arthritis and osteomyelitis from E cloacae. It is possible that the entry of infection that affected the prosthetic aortic valve in the first patient was via an intravenous catheter; in the second, a patient with acute granulocytic leukemia, via platelet-rich transfusion.
