Query: NC_004545:15650 Buchnera aphidicola str. Bp (Baizongia pistaciae), complete genome

Lineage: Buchnera aphidicola; Buchnera; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This organism is found in the aphid Baizongia pistaciae. Aphid endosymbiont. It is believed that the Buchnera provide the essential nutrients the host lacks. Besides a nutritional co-dependence, due to a co-existence of millions of years, Buchnera have lost the ability to produce cell surface components such as lipopolysaccharides. This makes for an obligate endosymbiont relationship between host and Buchnera. Buchnera are prokaryotic cells which belong to the gamma-Proteobacteria, closely related to the Enterobacteriaceae family. Phylogenetic studies using 16S rRNA indicate that the symbiotic relationship was established around 200-250 million years ago. Since Buchnera are closely related to Escherichia coli and Haemophilus influenzae, comparative genomic studies can shed light on the evolutionary mechanisms of intracellular endosymbiosis as well as the different underlying molecular basis between organisms with parasitic behavior and symbionts.

Subject: NC_004461:277291 Staphylococcus epidermidis ATCC 12228, complete genome

Lineage: Staphylococcus epidermidis; Staphylococcus; Staphylococcaceae; Bacillales; Firmicutes; Bacteria

General Information: This strain is a non-biofilm-forming, non-infection associated strain used for detection of residual antibiotics in food products. Common skin bacterium. Staphylcocci are generally found inhabiting the skin and mucous membranes of mammals and birds. Some members of this genus can be found as human commensals and these are generally believed to have the greatest pathogenic potential in opportunistic infections. This organism is the most prevalent and persistent Staphylococcus species on human skin. Has emerged as a common cause of nosocomial (hospital-acquired) infections, including catheter-associated infections and septicemia, particularly in immunocompromised patients. Resistant to many antibiotics including penicillins and cephalosporins.
