Antimicrobial susceptibilities of 23 strains of Desulfovibrio spp. were tested by Etest. Generally, Desulfovibrio spp. were highly susceptible to sulbactam-ampicillin, meropenem, clindamycin, metronidazole, and chloramphenicol: MIC(90)s of 6, 4, 0.19, 0.25, and 8 microg/ml, respectively. In addition, these strains generally showed high MICs to piperacillin and piperacillin-tazobactam. Desulfovi...

Desulfovibrio spp. are gram-negative, sulfate-reducing, and anaerobic bacteria found in the digestive tract of humans. Because Desulfovibrio spp. are infrequent causative agents of infectious diseases and are difficult to isolate and to identify from clinical specimens, the appropriate antibiotic therapy to infection with Desulfovibrio spp. has not been determined. We report the first case of l...

Two moderately halophilic sulfate-reducing bacteria were isolated from an African oil pipeline and designated strains SEBR 3640 and SEBR 2840T (T = type strain). Both of these strains possess traits that define the genus Desulfovibrio. The cells of both isolates were motile curved rods that had a single polar flagellum and contained desulfoviridin, and both isolates utilized lactate, pyruvate, ...

The genetic diversity of Desulfovibrio species in environmental samples was determined by denaturing gradient gel electrophoresis (DGGE) of PCR-amplified [NiFe] hydrogenase gene fragments. Five different PCR primers were designed after comparative analysis of [NiFe] hydrogenase gene sequences from three Desulfovibrio species. These primers were tested in different combinations on the genomic DN...

The complete genome sequence of Desulfovibrio piger FI11049 was determined. The genome consists of a single circular chromosome of 2,807,531 bp encoding seven rRNA operons, 76 tRNA genes, and 2,535 coding genes.

Desulfovibrio aespoeensis Aspo-2, DSM 10631(T), is a mesophilic, hydrogenotrophic sulfate-reducing bacterium sampled from a 600-m-deep subsurface aquifer in hard rock under the island of Äspö in southeastern Sweden. We report the genome sequence of this bacterium, which is a 3,629,109-bp chromosome; plasmids were not found.

Microbial sulfate reduction exhibits a normal isotope effect, leaving unreacted sulfate enriched in S and producing sulfide that is depleted in S. However, the magnitude of sulfur isotope fractionation is quite variable. The resulting changes in sulfur isotope abundance have been used to trace microbial sulfate reduction in modern and ancient ecosystems, but the intracellular mechanism(s) under...

Plasmid pJRDC800-1, containing the cyc gene encoding cytochrome c3 from Desulfovibrio vulgaris subsp. vulgaris Hildenborough, was transferred by conjugation from Escherichia coli DH5 alpha to Desulfovibrio desulfuricans G200. The G200 strain produced an acidic cytochrome c3 (pI = 5.8), which could be readily separated from the Hildenborough cytochrome c3 (pI = 10.5). The latter was indistinguis...

Streptomyces lunalinharesii strain 235 produces an antimicrobial substance that is active against sulfate reducing bacteria, the major bacterial group responsible for biofilm formation and biocorrosion in petroleum reservoirs. The use of this antimicrobial substance for sulfate reducing bacteria control is therefore a promising alternative to chemical biocides. In this study the antimicrobial s...

BACKGROUND Akkermansia muciniphila and Desulfovibrio spp. are commensal microbes colonising the mucus gel layer of the colon. Both species have the capacity to utilise colonic mucin as a substrate. A. muciniphila degrades colonic mucin, while Desulfovibrio spp. metabolise the sulfate moiety of sulfated mucins. Altered abundances of these microorganisms have been reported in ulcerative colitis (...
