Staphylococcus succinus sp. nov., isolated from Dominican amber

Int J Syst Bacteriol. 1998 Apr;48 Pt 2:511-8. doi: 10.1099/00207713-48-2-511.


Two bacterial isolates, designated AMG-D1T and AMG-D2, were recovered from 25-35-million-year-old Dominican amber. AMG-D1T and AMG-D2 biochemically most closely resemble Staphylococcus xylosus; they differ physiologically from other staphylococci. Fatty acid analysis and comparisons with extensive databases were unable to show relatedness to any specific taxon. Moreover, AMG-D1T and AMG-D2 contain tuberculostearic acid and meso-diaminopimelic acid, characteristic of the G + C-rich coryneform bacteria, as opposed to L-lysine characteristic of staphylococci. AMG-D1T and AMG-D2 have a G + C ratio of 35 mol%. Phylogenetic analysis with the 16S rRNA gene indicated that AMG-D1T and AMG-D2 were most closely related to Staphylococcus equorum, S. xylosus, Staphylococcus saprophyticus and other novobiocin-resistant staphylococci. Stringent DNA-DNA hybridization studies with AMG-D1T revealed similarities of 38% with S. equorum, 23% with S. xylosus and 6% with S. saprophyticus. The results indicate that AMG-D1T and AMG-D2 represent a novel species, which was named Staphylococcus succinus sp. nov. The type strain of the new species is AMG-D1 (ATCC 700337).
