Rochalimaea elizabethae sp. nov. isolated from a patient with endocarditis.

摘要: A Rochalimaea-like organism (strain F9251) was isolated from a patient with endocarditis after blood drawn for culture before antimicrobial therapy subcultured onto and chocolate agars incubated 2 weeks in 5% CO2. The strain phenotypically similar to known Rochalimaea species. cellular fatty acid composition of F9251 close but distinct those the three species most that R. vinsonii. Labeled DNA 59 67% related DNAs type strains described species, its 16S rRNA gene sequence 98.9% or more homologous their sequences. These findings support classification as new which name elizabethae sp. nov. is proposed. infected had large bacterial vegetations on his aortic valve cured antibiotics valve-replacement surgery. Recognition procedures required identify this other suggests clinical laboratories should prolong incubation times cultures tissue patients suspected endocarditis, fever unknown origin, immunocompromised so full spectrum disease caused by these organisms can be recognized.
