Microbe Identification
Microbe nameKlebsiella pneumoniae
NCBI Taxonomy ID573
DescriptionAcidaminococcus is a Gram-negative, cocci-shaped microbe that thrives in mesophilic temperatures, categorized as a Chemoheterotroph, and can be found in all body sites across various species, specifically being an Obligate Anaerobe. The Gram-negative staining property indicates the presence of a thin peptidoglycan layer in its cell wall, which is a characteristic shared among many pathogenic bacteria. The cocci shape allows for maximum surface area to volume ratio, enabling efficient exchange of nutrients and waste products. As a mesophilic microbe, Acidaminococcus grows best in moderate temperatures, typically between 20-45°C, making it well-suited for inhabiting various environments, including the human body. As a Chemoheterotroph, Acidaminococcus relies on chemical reactions to produce energy and cannot synthesize its own food, instead obtaining nutrients by breaking down organic matter. This metabolism allows it to thrive in a wide range of environments, from the human gut to soil and sediment. The ability to inhabit all body sites, including the skin, respiratory, gastrointestinal, and genitourinary tracts, makes Acidaminococcus a ubiquitous microbe. Its obligate anaerobic nature means it requires the absence of oxygen to grow, which is often found in deep tissue, gut, or other low-oxygen environments. Acidaminococcus plays a crucial role in the fermentation process, particularly in the breakdown of amino acids, producing short-chain fatty acids and other metabolites. This microbe has been implicated in various diseases, including periodontal disease, appendicitis, and bacteremia. The presence of Acidaminococcus in certain environments can also be used as an indicator of anaerobic conditions, making it a useful tool in environmental monitoring and forensic analysis.
