| Description | Prevotella amnii is a gram-negative, rod-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, across different species, and is an obligate anaerobe. As a gram-negative bacterium, P. amnii has a unique cell wall structure, which contributes to its resistance to certain antibiotics. Its rod shape allows it to inhabit and interact with various environments and hosts. The mesophilic temperature preference of P. amnii indicates that it grows best in moderate temperatures, typically between 20-45°C, which is consistent with the temperatures found in the human body. As a chemoheterotroph, P. amnii relies on organic compounds for energy and carbon, breaking down complex molecules into simpler ones to sustain its growth and survival. This metabolic ability enables P. amnii to inhabit diverse body sites, where it can exploit available nutrients. The presence of P. amnii in different body sites across various species suggests its adaptability and ability to form symbiotic relationships with its hosts. As an obligate anaerobe, P. amnii requires the absence of oxygen to grow and multiply, which is why it is often found in areas with low oxygen levels, such as the gut and oral cavity. P. amnii plays a significant role in the human microbiome, particularly in the context of pregnancy, where it has been implicated in preterm labor and other adverse outcomes. Research has shown that P. amnii can invade the amniotic cavity and trigger an inflammatory response, leading to premature birth. Further studies on P. amnii may provide valuable insights into the mechanisms of preterm labor and the development of strategies for prevention and treatment. |
