Query: NC_009778:259241 Enterobacter sakazakii ATCC BAA-894, complete genome
Lineage: Cronobacter sakazakii; Cronobacter; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Causes septicemia and enterocolitis in infants. Cronobacter sakazakii formerly Enterobacter sakazakii, is associated with infant septicemia, meningitis, and necrotizing enterocolitis. Originally isolated from powdered formula, it has also been shown to compartmentalize cerebral ventricles and cause brain abcesses in neonates. This species produces a yellow pigment when grown at 30 degrees C, but this fades at 37 degrees C.
Subject: NC_010556:691498 Exiguobacterium sibiricum 255-15, complete genome
Lineage: Exiguobacterium sibiricum; Exiguobacterium; Bacillales Family XII; Bacillales; Firmicutes; Bacteria
General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
