Query: NC_010163:145808 Acholeplasma laidlawii PG-8A chromosome, complete genome
Lineage: Acholeplasma laidlawii; Acholeplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria
General Information: Acholeplasma species are widely distributed in the nature and can be detected and isolated from different plant, avian, and mammalian sources. Acholeplasma laidlawii is found in soil, compost, wastewaters, cell cultures as well as in human tissues and in many animal species (birds, bovine, goat, equine, ovine, porcine, feline, rodent, primates). Acholeplasma laidlawii is capable of synthesizing glucose using a pyrophosphate-dependent 6-phosphofructokinase which has also been detected in other acholeplasmas (a good example of flexible metabolism). Additionally, Acholeplasma laidlawii and phytoplasmas are the only mollicutes known to use the universal genetic code, in which UGA is a stop codon.
Subject: NC_007296:35661 Streptococcus pyogenes MGAS6180, complete genome
Lineage: Streptococcus pyogenes; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain was isolated from an invasive disease in Texas, USA in 1998. Causes tonsilitis. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. 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 member of the normal human nasopharyngeal flora. S. pyogenes is a group A streptococcus and is the leading cause of uncomplicated bacterial pharyngitis and tonsillitis. This organism is commonly referred to by the lay press as "flesh eating bacteria".
