Klebsiella pneumoniae strain KP3CR KP3CR_84

Klebsiella pneumoniae strain KP3CR (accession SETY00000000.1) is a gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, primarily functioning as a chemoheterotroph. This strain is associated with various hosts, including humans (Homo sapiens), birds (Gallus gallus, Phasianidae, Aves), and several other vertebrates and invertebrates such as Danio rerio and Sus scrofa. The organism is characterized by its mobility, facilitated by the presence of flagella, and typically exists in chains, pairs, or as single cells. With an optimal growth temperature of 37°C, KP3CR is classified as mesophilic, thriving in moderate temperature environments. It possesses a single replicon and is enclosed by a double membrane, which is typical for gram-negative bacteria. Klebsiella pneumoniae KP3CR is notable for its pathogenicity in humans, being implicated in a wide range of health complications. These include bacteremia, urinary tract infections, pneumonia, and more severe conditions such as sepsis and meningitis. The organism's ability to cause infections extends to various anatomical sites, leading to conditions like liver abscesses and pyogenic liver abscesses. In terms of ecological roles, KP3CR is classified as free-living, indicating its capacity to thrive independently in various environments. Its diverse host range and pathogenic potential underscore its significance in both clinical and environmental microbiology, highlighting the complex interactions between pathogens and their hosts in different ecological contexts.
