Microbe Identification
Microbe nameVeillonella parvula
NCBI Taxonomy ID29466
DescriptionVeillonella parvula is a Gram-negative, cocci-shaped microbe that thrives in mesophilic temperatures, categorized as a Chemoheterotroph, and can be found in various body sites, including the oral cavity, gut, and urogenital tract, of numerous species, including humans, animals, and insects, and is an Obligate Anaerobe. As a Gram-negative microbe, Veillonella parvula has a unique outer membrane containing lipopolysaccharides, which provides protection against environmental stresses. Its cocci shape allows it to maintain a large surface area, facilitating the uptake of nutrients and interaction with other microbes. The mesophilic temperature preference of Veillonella parvula enables it to grow optimally at temperatures between 20-45°C, making it well-suited to inhabit various ecosystems. As a Chemoheterotroph, Veillonella parvula relies on organic compounds for energy and carbon, breaking down lactate, pyruvate, and other substrates to sustain its growth. The presence of Veillonella parvula in diverse body sites and species highlights its adaptability and ability to form symbiotic relationships with its hosts. As an Obligate Anaerobe, Veillonella parvula requires the absence of oxygen to grow, which is reflected in its metabolic pathways and enzymatic systems. Veillonella parvula plays a significant role in the fermentation of lactate, producing propionic acid, acetate, and carbon dioxide, which can influence the pH and composition of its environment, and its ability to metabolize lactate has implications for the development of novel therapeutic strategies, particularly in the treatment of diseases associated with dysbiosis, such as periodontitis and inflammatory bowel disease.
