| Description | Citrobacter amalonaticus is a Gram-negative, rod-shaped bacterium that thrives in moderate temperatures, classified as a mesophilic organism. As a chemoheterotroph, it derives energy and carbon from organic compounds, which it metabolizes in various environments. This microbe is typically found in the gastrointestinal tracts of humans and animals, as well as in soil and water, indicating its widespread presence in the ecosystem. The Gram-negative characteristic of C. amalonaticus signifies that it possesses a thin peptidoglycan layer surrounded by an outer membrane, which contains lipopolysaccharides that contribute to its pathogenic potential and immune evasion. Its rod shape allows for efficient movement and colonization in diverse environments, enhancing its survival abilities. As a mesophile, C. amalonaticus prefers moderate temperatures, typically between 20°C and 45°C, making it well-suited for life in warm-blooded hosts. Being a chemoheterotroph, C. amalonaticus relies on organic compounds for both energy and carbon, allowing it to thrive in nutrient-rich environments such as the intestinal flora. This microbe is classified as a facultative anaerobe, which means it can grow in both the presence and absence of oxygen. This adaptability is crucial for its survival in the host gut, where oxygen levels may vary significantly. Citrobacter amalonaticus is also recognized for its potential pathogenicity, as it can be associated with urinary tract infections and other opportunistic infections, particularly in immunocompromised individuals. Its ability to produce certain enzymes, such as urease, contributes to its pathogenic profile. Furthermore, the microbe plays a role in biogeochemical cycling, particularly in nitrogen transformations, highlighting its ecological significance beyond human health. |
