Query: NC_015433:1998427 Streptococcus suis ST3 chromosome, complete genome
Lineage: Streptococcus suis; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. This organism is a pathogen of pigs and is responsible for a variety of diseases including meningitis, arthritis and pneumonia. Occasionally this organism can infect humans causing septicemia, meningitis and endocarditis
Subject: NC_010556:6612 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.
