Query: NC_014802:392852 Campylobacter jejuni subsp. jejuni ICDCCJ07001 chromosome, complete

Lineage: Campylobacter jejuni; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria

General Information: Gram-negative, microaerophilic, flagellate, spiral bacterium, Campylobacter species are the leading cause of food-borne gastroenteritis in developed countries. Infection with C. jejuni is the most frequent antecedent to a form of neuromuscular paralysis known as Guillain-Barre syndrome (GBS). Strain ICDCCJ07001 was isolated following a GBS outbreak in Shuangyang, a town in northern China in 2007, from a severely affected 15 year-old girl GBS patient who had been on a ventilator for 180 days. Her clinical symptoms were motor axonal neuropathy. This organism is the leading cause of bacterial food poisoning (campylobacteriosis) in the world, and is more prevalent than Salmonella enteritis (salmonellosis). Found throughout nature, it can colonize the intestines of both mammals and birds, and transmission to humans occurs via contaminated food products. This organism can invade the epithelial layer by first attaching to epithelial cells, then penetrating through them. Systemic infections can also occur causing more severe illnesses.

Subject: NC_020211:4168189 Serratia marcescens WW4, complete genome

Lineage: Serratia marcescens; Serratia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This organism was discovered in 1819 by Bizio who named the organism after the Italian physicist Serrati. It was considered a nonpathogenic organism until late in the 20th century, although pathogenicity was noted as early as 1913. Serratia marcescens is an opportunistic human pathogen that is increasingly associated with life-threatening hospital-acquired infections. It is an environmental organism that has a broad host range, and is capable of infecting vertebrates and invertebrates, as well as plants. In humans, Serratia marcescens can cause meningitis (inflammation of the membrane surrounding the brain and spinal cord), endocarditis (inflammation of heart muscle) and pyelonephritis (inflammation of the kidneys). Many strains are resistant to multiple antibiotics. Environmental isolates are noted by production of the red pigment prodigiosin.
