Description and Significance

Variovorax durovernensis (V. durovernensis) is a gram-negative bacterium with a curved rod-like cellular morphology. This bacterium typically finds its habitat is soil but has been found in human infections specifically located in the aorta. V. durovernensis is significant because of its role in medicine, potential technology advancements, and ecological health such as plant growth.

Genome Structure

V. durovernensis is approximately 7,390,000 base pairs in size. V. durovernensis has a single circular chromosome. In addition, V. durovernensis has the feature to adapt to extreme environmental conditions and bioremediation. The sequence itself does not differ far from other Variovorax; however, V. durovernensis has a unique sequence that provides a stronger ability to adapt to extreme environmental changes.

Cell Structure, Metabolism and Life Cycle

V. durovernensis is a gram-negative bacterium that has a rod-like cellular morphology. V. durovernensis typically receives energy through the process of aerobic respiration. V. durovernensis contributes to life through degradation of environmental pollutants.

Ecology and Pathogenesis

V. durovernensis is typically found in an environment that is soil-based. The bacterium itself shares a symbiotic relationship with the surrounding plants within the soil habitat. V. durovernensis promotes growth and uptake of nutrients. Regarding biogeochemical significance, V. durovernensis performs bioremediation and allows the Recyling of the environment's natural pollutants.

Although V. durovernensis has been recently discovered to influence disease and overall virulence, V. durovernensis targets immunocompromised humans. V. durovernensis remains to have only been discovered in humans aortas and has only been known to cause fevers. V. durovernensis has a presentation of infection-like features.
