Desulfovibrio spp. are gram negative, obligate anaerobes capable of reducing sulfate. They have caused infections in humans, but very rarely. They are slow growers and difficult to identify. Hence, they are often overlooked and their actual presence goes unnoticed. Here, we describe a case of a 15- year old boy who was involved in a road traffic accident and he presented with seropurulent discharge from a depressed fracture wound on the forehead. Desulfovibrio vulgaris (D.vulgaris), was isolated from the pus discharge, the first to be reported. The characteristic desulfoviridin pigment production in the organism aided in the identification. The infection was successfully managed with pain reliever and course of amoxicillin - clavulanic acid and linezolid.

Unlabelled: Ubiquitous in nature, biofilms provide stability in a fluctuating environment and provide protection from stressors. Biofilms formed in industrial processes are exceedingly problematic and costly. While biofilms of sulfate-reducing bacteria in the environment are often beneficial because of their capacity to remove toxic metals from water, in industrial pipelines, these biofilms cause a major economic impact due to their involvement in metal and concrete corrosion.

The initiation and progression of colorectal cancer (CRC) are intimately associated with genetic, environmental and biological factors. (DSV), a sulfate-reducing bacterium, has been found excessive growth in CRC patients, suggesting a potential role in carcinogenesis. However, the precise mechanisms underlying this association remain incompletely understood.

Understanding the extracellular electron transfer mechanisms of electroactive bacteria could help determine their potential in microbial fuel cells (MFCs) and their microbial syntrophy with redox-active minerals in natural environments. However, the mechanisms of extracellular electron transfer to electrodes by sulfate-reducing bacteria (SRB) remain underexplored. Here, we utilized double-chamber MFCs with carbon cloth electrodes to investigate the extracellular electron transfer mechanisms of Hildenborough (H), a model SRB, under varying lactate and sulfate concentrations using different H mutants.

This research examined the varying susceptibility of pure copper (Cu), 90/10 copper-nickel (Cu-Ni) alloy, 70/30 Cu-Ni alloy, and pure nickel (Ni) to microbiologically influenced corrosion (MIC) induced by Desulfovibrio vulgaris, with a focus on the elemental composition of the materials. The results revealed a progressive shift in MIC behavior across these metals and alloys, with increased corrosion severity observed as Ni content decreased. Element Ni improved the corrosion resistance of the alloy while also preventing the growth of microorganisms.

, resident gut sulfate-reducing bacteria (SRB), are found to overgrow in diseases such as inflammatory bowel disease and Parkinson's disease. They activate a pro-inflammatory response, suggesting that may play a causal role in inflammation. Class I phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway regulates key events in the inflammatory response to infection.
