General Information: Isolation: water fern Azolla; Temp: Mesophile; Habitat: Host. Nostoc azollae, formerly Anabaena azollae, is a cyanobacterial symbiont of the water fern Azolla, commonly known as 'duckweed'. Nostoc azollae is a nitrogen-fixer and provides nitrogen to the host plant.
Subject: NC_007946:3683371 Escherichia coli UTI89, complete genome
Lineage: Escherichia coli; Escherichia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain (UTI89) is a uropathogenic strain isolated from a woman with uncomplicated cystitis (bladder inflammation) that has been demonstrated to cause cystitis in a murine urinary tract infection model. This organism was named for its discoverer, Theodore Escherich, and is one of the premier model organisms used in the study of bacterial genetics, physiology, and biochemistry. This enteric organism is typically present in the lower intestine of humans, where it is the dominant facultative anaerobe present, but it is only one minor constituent of the complete intestinal microflora. E. coli, is capable of causing various diseases in its host, especially when they acquire virulence traits. E. coli can cause urinary tract infections, neonatal meningitis, and many different intestinal diseases, usually by attaching to the host cell and introducing toxins that disrupt normal cellular processes.
