Klebsiella pneumoniae strain NUBRI-K 137

Klebsiella pneumoniae strain NUBRI-K 137 is a Gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism. This strain is classified as a chemoheterotroph, deriving energy from organic compounds, and is capable of existing in various cell arrangements, including chains, pairs, and singles. It is motile and possesses flagella, allowing for movement within its host-associated habitat. Optimal growth for NUBRI-K 137 occurs at 37°C, indicating its mesophilic nature. The bacterium has one replicon and two membranes, a typical feature of Gram-negative organisms. It exhibits a free-living biotic relationship and has a broad host range, affecting various species including humans (Homo sapiens), chickens (Gallus gallus), and other vertebrates such as zebrafish (Danio rerio) and domestic animals like dogs (Canis lupus familiaris) and pigs (Sus scrofa). Klebsiella pneumoniae is known for its pathogenicity in humans, causing a wide array of health issues. These include bacteremia, urinary tract infections, pneumonia, and more severe conditions such as sepsis and meningitis. The bacterium's ability to cause such diverse infections highlights its adaptability and potential for opportunistic pathogenicity in various environments. Ecologically, the presence of K. pneumoniae in diverse hosts suggests its role in microbial communities associated with both humans and animals. Its pathogenic potential, coupled with its ability to thrive in multiple hosts, underscores the importance of monitoring this strain in clinical and environmental contexts to understand its impact on health and disease dynamics.
