| Description | Enterobacter hormaechei is a Gram-negative, rod-shaped bacterium that thrives as a mesophile, preferring moderate temperatures. It is classified as a chemoheterotroph, deriving energy and carbon from organic compounds, and is a facultative anaerobe, capable of surviving in both aerobic and anaerobic environments. This versatile microbe is commonly found in various body sites, including the gastrointestinal tract, respiratory system, and urinary tract, making it an important organism in both environmental and clinical settings. As a Gram-negative bacterium, Enterobacter hormaechei possesses a thin peptidoglycan layer surrounded by an outer membrane containing lipopolysaccharides, contributing to its resilience against certain antibiotics and the host's immune response. Its rod-shaped morphology allows for mobility and colonization in diverse environments, including human hosts, where it can sometimes lead to opportunistic infections. The mesophilic nature of this microbe enables it to thrive at body temperature (around 37°C), which is crucial for its survival in a host. Being a chemoheterotroph, E. hormaechei utilizes various organic substrates for growth, which facilitates its presence in environments rich in organic matter, such as fecal matter and hospital waste. Its facultative anaerobic capability allows it to adapt to different oxygen levels, enabling it to colonize various body niches effectively. E. hormaechei has gained significant attention due to its potential role in nosocomial infections, especially in immunocompromised patients. Its ability to acquire antibiotic resistance genes through horizontal gene transfer further complicates treatment options. The emergence of multidrug-resistant strains highlights the importance of monitoring this microbe in clinical microbiology and public health settings. |
