Ecology and Pathogenesis

Sulfate reducers thrive in marine systems, owing to the high concentration of sulfate ions in seawater. They can be found in various environments such as oil field production waters, acid mine drainage waters, sewage, and soil. However the genetic structures of the sulfate-reducing bacteria differ in different environments (Verstreken et. al., 2012). This proves that Desulfovibrio desulfuricans has an excellent ability to adapt to its surroundings while maintaining an optimal cell structure for nutrient uptake and allows for the anaerobic production of methylmercury. D. desulfuricans are not known to be pathogenic, however an infection of this microbe into the human body can prove to be detrimental to one’s health. We see an example of this in the case of a 69 year old woman who had been hospitalized with complaints of stomach irritation, irregular bowel movements, diarrhea, and fever. The final diagnoses being D. desulfuricans bacteremia occurring in an immunocompromised host with CMV colitis (Voorduow et. al., 1995). Doctors then incubated the strain revealing a resistance to piperacillin-tazobactam. Desulfovibrio desulfuricans culture under anoxic conditions is more likely to form colonies in free living cells than particle associated environments (Voorduow et. al., 1995).

Current Research

Desulfovibro desulfuricans strain ND132 presents an excellent opportunity for the study of mercury methylation because while being a typical anaerobic mesophilic bacterium with wide tolerance of pH and salinity, it also grows well with fumurate as electron acceptor, which prevents sulfide inhibition of mercury methylation (Gilmour et al., 2011). Its genome sequencing allows comparative transcriptomic and proteomic study against other Desulfovibrio species (Gilmour, et al., 2011) Additional research includes the effects of large colony blooms in seawater and effects of infections in the human body by D. desulfuricans. One of the main research proposals currently being performed on D.desulfuricans is the study of how methylmercury production occurs with this organism’s cellular respiration. D.desulfuricans is the only organism in which pathways of its methylation have been somewhat defined (Gilmour et. al., 2011). This team of scientists used enriched stable mercury isotopes to show that ND132 simultaneously produces and degrades methylmercury (MeHg) during growth but does not produce elemental Hg. A large colony of strain ND132 may cause harm to someone who comes in contact with the colony as methylmercury is known to cause brain and nervous system damage. There is still much research that can be done on this organism which may prove beneficial to human society as we learn about new ways to prevent corrosion caused by ND132, or as we may be able to utilize their respiration in some wastewater treatment plants.
