Query: NC_003869:74836 Thermoanaerobacter tengcongensis MB4, complete genome
Lineage: Caldanaerobacter subterraneus; Caldanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: This organism was originally isolated from a hot spring in Tengcong, China, and is the type strain for the species. Genomic analysis indicates it is similar to Bacillus halodurans and that it has one of the most biased leading strand distribution of genes. Although the organism has not been observed to be motile or to sporulate, it does contain genes for both functions. The bacterium produces acetate and ethanol from glucose and cannot degrade xylan and cellulose.
Subject: 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.
