| Popis: | We describe three cases of Anaerobiospirillum succiniciproducens bacteremia from Australia. We believe one of these cases represents the first report of A. succiniciproducens bacteremia in a human immunodeficiency virus (HIV)-infected individual. The other two patients had an underlying disorder (one patient had bleeding esophageal varices complicating alcohol liver disease and one patient had non-Hodgkin’s lymphoma). A motile, gram-negative, spiral anaerobe was isolated by culturing blood from all patients. Electron microscopy showed a curved bacterium with bipolar tufts of flagella resembling Anaerobiospirillum spp. Sequencing of the 16S rRNA genes of the isolates revealed no close relatives (organisms likely to be in the same genus) in the sequence databases, nor were any sequence data available for A. succiniciproducens . This report presents for the first time the 16S rRNA gene sequence of the type strain of A. succiniciproducens , strain ATCC 29305. Two of the three clinical isolates have sequences identical to that of the type strain, while the sequence of the other strain differs from that of the type strain at 4 nucleotides. |
