Query: NC_014751:449001 Mycoplasma leachii PG50 chromosome, complete genome
Lineage: Mycoplasma leachii; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: Mycoplasma leachii, formerly Mycoplasma sp. 'bovine group 7', was originally isolated from cattle suffering from arthritis and mastitis in Australia. Mycoplasma leachii is part of the mycoides cluster like Mycoplasma mycoides SC and Mycoplasma capricolum, but it can infect both bovine and caprine hosts.
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.
