| Description | Dialister invisus is a Gram-negative, curved rod-shaped microbe that thrives in mesophilic temperatures, classified as a Chemoheterotroph, and can be found in various body sites including the gastrointestinal tract, respiratory tract, and genitourinary tract of humans and animals, and is an Obligate Anaerobe. The Gram-negative characteristic indicates that the microbe's cell wall is composed of a thin peptidoglycan layer, which is responsible for its negative staining property. The curved rod shape of D. invisus allows it to navigate through tight spaces and adhere to host cells. As a mesophile, D. invisus grows best in moderate temperatures, typically between 20-40°C, which is consistent with its presence in the human body. As a Chemoheterotroph, D. invisus relies on external sources of energy and organic compounds for growth and survival, breaking down complex molecules into simpler ones to sustain its metabolic processes. The microbe's presence in various body sites suggests its ability to adapt to different environments and exploit available nutrients. The Obligate Anaerobe nature of D. invisus means that it requires the absence of oxygen to grow, which is consistent with its habitat in the human gut and other low-oxygen environments. Dialister invisus plays a significant role in the human microbiome, particularly in the gut, where it contributes to the fermentation of complex carbohydrates and the production of short-chain fatty acids, which are essential for maintaining a healthy gut epithelium. Its presence has also been linked to various diseases, including periodontal disease and bacterial vaginosis, highlighting the complex relationship between the microbe and its host. Recent studies have also explored the potential of D. invisus as a biomarker for certain diseases, due to its unique metabolic profile and ability to thrive in specific environments. |
