Klebsiella pneumoniae strain EuSCAPE_TR274

Klebsiella pneumoniae strain EuSCAPE_TR274 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, functioning as a chemoheterotroph. This strain is known for its mobility, facilitated by the presence of flagella, and it typically forms chains, pairs, or single cells. The optimal growth temperature for this mesophilic organism is 37°C, which aligns with the typical human body temperature, emphasizing its adaptation to host-associated environments. EuSCAPE_TR274 has been identified as a pathogen in various hosts, including Homo sapiens, Gallus gallus, and multiple other metazoans, highlighting its versatility and potential zoonotic implications. The strain is associated with a wide range of health effects in humans, including bacteremia, urinary tract infections, pneumonia, and more severe conditions such as sepsis and meningitis. These infections underscore the clinical significance of Klebsiella pneumoniae as a major opportunistic pathogen, particularly in immunocompromised individuals. The ecological insight provided by the biotic relationship of EuSCAPE_TR274 as free-living suggests that it may thrive in diverse environments beyond immediate hosts, potentially contributing to its pathogenicity. The ability to inhabit various hosts and the broad spectrum of infections associated with this strain underscore the importance of monitoring Klebsiella pneumoniae in both clinical and environmental settings to understand its epidemiology and impact on public health.
