Citrobacter braakii strain HH5 21

Citrobacter braakii strain HH5 21 is a Gram-negative bacterium characterized by its rod-shaped morphology and the presence of flagella, which enables motility. This strain has a single replicon, indicating a streamlined genetic architecture that may influence its adaptability and replication efficiency. C. braakii is known to inhabit a variety of hosts, including Homo sapiens (humans), Oncorhynchus mykiss (rainbow trout), Ictalurus punctatus (channel catfish), Xenopus laevis (African clawed frog), Kurixalus bisacculus (a species of frog), and Oophaga histrionica (a poison dart frog). This diverse range of hosts suggests that C. braakii strain HH5 21 may have a versatile ecological role, potentially serving as a commensal organism in these species or, in some instances, contributing to disease. The presence of C. braakii in both aquatic and terrestrial ecosystems, as evidenced by its association with various amphibian and fish hosts, highlights its adaptability to different environments. The strain's accession number is SJSJ00000000.1, which provides a pathway for further genomic exploration and understanding of its biological functions. In summary, C. braakii strain HH5 21 exemplifies the adaptability of bacteria to diverse hosts and environments, which may play a crucial role in ecosystem dynamics and host-microbe interactions. Further studies on this strain could shed light on its ecological significance and potential applications in biotechnology or environmental microbiology.
