Gardnerella vaginalis ATCC 14019

Gardnerella vaginalis ATCC 14019 is a Gram-positive, rod-shaped bacterium that is classified as a chemoheterotroph, deriving its energy from organic compounds. This organism thrives in anaerobic conditions, making it well-suited for its habitat in the human host, particularly within the vaginal microbiome. It has a mesophilic temperature range, with an optimal growth temperature of 37°C, indicative of its adaptation to human body temperature. G. vaginalis is non-motile and does not possess flagella, which suggests that it relies on other mechanisms for its dispersal within the host environment. It contains a single membrane and one replicon, indicating a relatively simple cellular structure that aligns with its free-living biotic relationship. The pathogenicity of G. vaginalis is notable, as it is associated with bacterial vaginosis, a condition that can lead to various reproductive health issues. Despite being a part of the normal vaginal flora in some individuals, its overgrowth can disrupt the ecological balance, leading to adverse health effects. Understanding the ecological role of G. vaginalis is essential, as it highlights the complex interactions within the vaginal microbiome. Its capacity to thrive in anaerobic conditions while causing pathogenic effects under certain circumstances illustrates the delicate balance that exists between beneficial and harmful microorganisms in host-associated habitats. The accession number for further genomic insights is NC_014644.1.
