Klebsiella pneumoniae strain EuSCAPE_ES273

Klebsiella pneumoniae strain EuSCAPE_ES273 is a Gram-negative, rod-shaped bacterium classified as a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. This organism is chemoheterotrophic, deriving its energy from organic compounds, and typically exhibits a mesophilic temperature range, with an optimal growth temperature of 37°C. Its cell arrangement can be observed in chains, pairs, and singles, and it possesses flagella, which contribute to its mobility. EuSCAPE_ES273 is notable for its diverse biotic relationships, being free-living and associated with various hosts including Homo sapiens, Gallus gallus, and multiple other metazoans and plants. This wide host range suggests a significant ecological versatility and potential for transmission across species. Clinically, K. pneumoniae strain EuSCAPE_ES273 is linked to a multitude of health effects, including bacteremia, urinary tract infections, pneumonia, and various intra-abdominal infections. Its pathogenicity in humans underscores its role as an opportunistic pathogen, particularly in immunocompromised individuals. The strain has been implicated in severe conditions such as neonatal sepsis and pyogenic liver abscesses, highlighting its potential for causing significant morbidity. The presence of a single replicon and two membranes characterizes its cellular structure, typical of Gram-negative bacteria. Understanding the ecological role and pathogenic potential of K. pneumoniae strain EuSCAPE_ES273 is essential for developing strategies to manage infections and prevent disease spread, particularly in healthcare settings where it poses a substantial risk.
