Klebsiella pneumoniae strain EuSCAPE_GR139

Klebsiella pneumoniae strain EuSCAPE_GR139 is a Gram-negative, rod-shaped bacterium classified as a facultative anaerobe and a chemoheterotroph. It exhibits a diverse cell arrangement, often found in chains, pairs, or as singles. This strain is notable for its mobility, attributed to the presence of flagella. It thrives optimally at 37°C and falls within the mesophilic temperature range. The ecological niche of EuSCAPE_GR139 is primarily host-associated, where it engages in a free-living biotic relationship. It has a wide range of host organisms, including Homo sapiens, various species of birds (Phasianidae, Aves), mammals (Canis lupus familiaris, Sus scrofa, Equidae), and aquatic species such as Danio rerio. This broad host range highlights its adaptability and potential for transmission across different environments and species. EuSCAPE_GR139 is associated with a variety of serious health effects, including bacteremia, urinary tract infections, pneumonia, and more severe conditions such as sepsis and meningitis. Its pathogenicity in humans is of particular concern, given its role in various infections that can lead to severe clinical outcomes. The presence of a single replicon and two membranes indicates its structural complexity, typical of many Gram-negative bacteria. Understanding the traits of Klebsiella pneumoniae strain EuSCAPE_GR139 enhances our knowledge of its ecological and pathogenic roles, particularly in human health contexts, emphasizing the importance of monitoring and controlling its spread among diverse hosts.
