| Description | Atopobium parvulum DSM 20469 is a Gram-positive, rod-shaped bacterium that is classified as a mesophile, with a temperature preference typically around 30-37°C. It is a chemoheterotroph, meaning it derives its energy from organic compounds. This organism is primarily found in the human microbiome, particularly in the oral cavity and the urogenital tract, where it plays a role in the complex microbial communities of these regions. A notable characteristic of Atopobium parvulum is its classification as an obligate anaerobe, thriving in environments devoid of oxygen, which influences its metabolic processes and ecological interactions. The Gram-positive nature of Atopobium parvulum indicates a thick peptidoglycan layer in its cell wall, which can affect its susceptibility to certain antibiotics and its overall stability in various environments. The rod-shaped morphology allows it to adapt efficiently within the diverse habitats it resides in, while its mesophilic nature suggests it is well-suited to the warm conditions of the human body. As a chemoheterotroph, Atopobium parvulum metabolizes organic substrates, which can contribute to both symbiotic relationships with the host and the development of certain health conditions. Atopobium parvulum is considered part of normal flora but has also been linked to various health concerns, particularly in cases of bacterial vaginosis, where imbalances in the microbial community can lead to adverse effects. Its interactions with other microorganisms and the host immune system highlight its potential role in health and disease, making it a subject of study in microbiology and health sciences. |
