| Description | Parabacteroides sp. D13 is a Gram-negative, rod-shaped bacterium that thrives in anaerobic environments and is classified as a chemotroph. This microbe prefers mesophilic temperatures, typically flourishing around 30-37°C, reflecting its adaptation to the warm conditions of the mammalian gut, where it is predominantly found. Parabacteroides sp. D13 resides in various body sites, primarily the gastrointestinal tract of humans and animals, where it plays a crucial role in the digestive microbiome. The Gram-negative nature of Parabacteroides sp. D13 is indicative of its cell wall structure, characterized by a thin peptidoglycan layer and an outer membrane, which contributes to its resistance against certain antibiotics and influences its interactions within the gut environment. The rod shape is a common morphological feature among many gut bacteria, facilitating motility and biofilm formation, which are essential for establishing a robust microbial community. As a chemotroph, Parabacteroides sp. D13 derives its energy from organic compounds, primarily by fermenting carbohydrates and proteins, a metabolic trait that underscores its role in breaking down complex food materials within the gut. This process not only aids digestion but also produces short-chain fatty acids, which are beneficial for intestinal health. Parabacteroides sp. D13 is classified as an obligate anaerobe, meaning it cannot survive in the presence of oxygen. This adaptation is key to its ecological niche, as oxygen is generally scarce in the gut environment. Notably, Parabacteroides species are recognized for their potential health implications, including their involvement in the modulation of host immune responses and the synthesis of essential vitamins. Additionally, they have garnered attention in research for their potential role in the development of therapeutic strategies for metabolic disorders, highlighting their significance beyond mere commensalism in human health. |
