Nosocomial bacteremia caused byBacillus species

Abstract
During a six year period, 11 cases of bacteremia caused byBacillus spp. were observed corresponding to 1 % of all bacteremic episodes in our hospital. Most patients had cancer as underlying disease. All cases of positive blood cultures were associated with a clinical syndrome compatible with sepsis including high fever. None of the subsequent deaths could be related to the bacteremia caused byBacillus spp. Four of eight cases ofBacillus subtilis bacteremia were associated with the absorption of an oral preparation containingBacillus subtilis spores, which was administered empirically in some units of the hospital to reduce what was considered to be tubefeeding related diarrhea.
