Klebsiella pneumoniae strain EuSCAPE_IT199

Klebsiella pneumoniae strain EuSCAPE_IT199 is a Gram-negative, rod-shaped bacterium that displays mobility due to the presence of flagella. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It primarily acts as a chemoheterotroph, deriving its energy from organic compounds. The optimal growth temperature for EuSCAPE_IT199 is around 37°C, which aligns with its habitat as a host-associated organism, often found in association with various species, including Homo sapiens and other animals such as Gallus gallus and Sus scrofa. This strain is notable for its diverse biotic relationships, as it can exist in free-living states while also being pathogenic to humans, causing a range of serious health effects including bacteremia, urinary tract infections, pneumonia, and sepsis. Klebsiella pneumoniae is recognized for its role in both community-acquired and healthcare-associated infections, with implications for public health due to its ability to cause severe illnesses such as neonatal sepsis and pyogenic liver abscesses. With a single replicon and a double membrane structure, EuSCAPE_IT199 is nonsporulating, which contributes to its vulnerability in certain environments where sporulation would provide a survival advantage. The strain's broad host range across various species, including mammals and birds, emphasizes its ecological adaptability and the potential for cross-species transmission, raising concerns regarding the management of infections in both human and veterinary medicine.
