| Description | Veillonella dispar is a Gram-negative, non-motile, non-sporulating coccus that thrives in the temperature range of mesophily, between 25-40°C. This microbe is a heterotroph, relying on organic compounds for energy and carbon, as it lacks the ability to produce its own food through photosynthesis or chemosynthesis. Veillonella dispar derives energy through the breakdown of complex organic molecules, releasing energy in the form of ATP. As a part of the normal flora, Veillonella dispar can be found in various body sites across different species, including the oral cavity, skin, respiratory tract, and gastrointestinal tract. In fact, it is a common resident of the human oral cavity, where it plays a role in the development of dental caries. Veillonella dispar is an anaerobe, preferring to thrive in environments where oxygen is limited or absent. It is classified as an obligate anaerobe, meaning that it is unable to survive in the presence of oxygen and would be inhibited or killed off by exposure to high levels of oxygen. In terms of its oxygen preference, Veillonella dispar is an obligate anaerobe, requiring a low-oxygen environment to carry out its metabolic processes. It is unable to tolerate even small amounts of oxygen and would be suppressed or eliminated by the introduction of oxygen into its environment. Veillonella dispar has been linked to various diseases, including dental caries, periodontitis, and possibly even respiratory infections. Despite its role in disease, this microbe plays a crucial part in the ecosystem of the human body, serving as a food source for other microorganisms and helping to break down complex organic molecules. Its ability to thrive in low-oxygen environments makes it an important component of the anaerobic microbiome, highlighting the importance of understanding the complexities of microbial communities within the human body. |
