Klebsiella pneumoniae strain EuSCAPE_AT023

Klebsiella pneumoniae strain EuSCAPE_AT023 is a significant pathogen characterized primarily by its negative Gram stain and rod shape. This strain is a chemoheterotroph, deriving energy from organic compounds, and is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It typically exists in chains, pairs, or as single cells, and possesses flagella, which contribute to its mobility. The strain is mesophilic, with an optimal growth temperature of 37°C, making it well-suited to the human body, where it is commonly found as a host-associated organism. Its biotic relationship is classified as free-living, indicating that it can survive independently while still being capable of causing a range of health issues in various hosts, including humans and several animal species such as Gallus gallus (chickens), Danio rerio (zebrafish), and Canis lupus familiaris (domestic dogs). Klebsiella pneumoniae strain EuSCAPE_AT023 is linked to numerous health complications, including bacteremia, urinary tract infections, pneumonia, and a range of intra-abdominal infections. Its pathogenicity is particularly concerning in human health, as it is responsible for severe conditions such as sepsis and neonatal sepsis. The strain's diverse host range highlights its ecological adaptability and potential for zoonotic transmission, emphasizing the need for ongoing surveillance and research to understand its impact on both human and animal health.
