Query: NC_017501:147933 Neisseria meningitidis 8013, complete genome

Lineage: Neisseria meningitidis; Neisseria; Neisseriaceae; Neisseriales; Proteobacteria; Bacteria

General Information: The second of two pathogenic Neisseria, this organism causes septicemia and is the leading cause of life-threatening meningitis (inflammation of the meninges, the membrane surrounding the brain and spinal cord) in children. This organism typically residies in the nasopharynx cavity but can invade the respiratory epthelial barrier, cross into the bloodstream and the blood brain barrier, and cause inflammation of the meninges. Pathogenicity factors include the surface proteins (porins and opacity proteins), and the type IV pilus (which is also found in Neisseria gonorrhoeae). This organism, like Neisseria gonorrhoeae, is naturally competent, and protein complexes at the cell surface recognize the uptake signal sequence in extracellular DNA, an 8mer that is found at high frequency in Neisseria chromosomal DNA.

Subject: NC_010645:3720501 Bordetella avium 197N, complete genome

Lineage: Bordetella avium; Bordetella; Alcaligenaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: This strain is a spontaneous nalidixic acid-resistant derivative of virulent strain 197. This group of organisms is capable of invading the respiratory tract of animals and causing severe diseases. They express a number of virulence factors in order to do this including filamentous hemagglutins for attachment, cytotoxins, and proteins that form a type III secretion system for transport of effector molecules into host cells. This organism infects the respiratory tract of birds, and causes bordetellosis in commercially important animals such as turkeys, resulting in devastating losses every year due to secondary infections.
