W. Tee et al., PROBABLE NEW SPECIES OF DESULFOVIBRIO ISOLATED FROM A PYOGENIC LIVER-ABSCESS, Journal of clinical microbiology, 34(7), 1996, pp. 1760-1764
A fastidious, slowly growing, spiral gram-negative bacterium was isola
ted from the liver abscess of an 82-year-old man with a 3-week history
of febrile illness. The organism was an obligate anaerobe that grew a
t 37 and 42 degrees C but not at 25 degrees C. Its vibrioid or spiral
morphology on Gram staining, rapid progressive motility, electron micr
ograph features, and biochemical tests were all consistent with the or
ganism belonging to the genus Desulfovibrio. 16S rRNA gene sequencing
of this organism demonstrated a 97% similarity to Desulfovibrio desulf
uricans with 45 nucleotide differences, suggesting that it is a new sp
ecies of Desulfovibrio.
