| Description | Gemella is a gram-positive, cocci-shaped microbe that thrives in mesophilic temperatures, categorized as a chemoheterotroph, and can be found in all body sites of various species, including the respiratory, gastrointestinal, and genitourinary tracts, and is typically an obligate anaerobe. The gram-positive characteristic indicates that the microbe's cell wall contains a thick peptidoglycan layer, which retains the crystal violet stain during the gram staining process. The cocci shape allows Gemella to maintain a stable structure and withstand various environmental pressures. As a mesophile, Gemella grows best in moderate temperatures, between 20-45°C, which is suitable for its habitat in the human body.As a chemoheterotroph, Gemella relies on chemical reactions to obtain energy and organic compounds from its environment, rather than producing its own through photosynthesis or other means. This characteristic is essential for its survival in the human body, where it can feed on various nutrients and waste products. The presence of Gemella in all body sites of various species suggests that it is a highly adaptable microbe, capable of colonizing diverse environments. Its obligate anaerobic nature means that it requires the absence of oxygen to grow and thrive, which is often the case in the deep tissues and organs of the human body. Gemella plays a significant role in the human microbiome, particularly in the oral cavity, where it contributes to the formation of dental plaque and the development of periodontal diseases. Its presence has also been linked to various infections, including endocarditis and bacteremia. The ability of Gemella to form biofilms and adhere to surfaces makes it a challenging microbe to eradicate, and its resistance to certain antibiotics has raised concerns about its potential impact on human health. |
