Query: NC_009707:1685381 Campylobacter jejuni subsp. doylei 269.97 chromosome, complete
Lineage: Campylobacter jejuni; Campylobacter; Campylobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: Isolated from a blood sample of human bacteremia in South Africa. Causes food poisoning. 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_012225:2247796 Brachyspira hyodysenteriae WA1, complete genome
Lineage: Brachyspira hyodysenteriae; Brachyspira; Brachyspiraceae; Spirochaetales; Spirochaetes; Bacteria
General Information: Brachyspira hyodysenteriae is the causative agent of swine dysentery, which is a severe mucohemorrhagic diarrheal disease of pigs that has economic significance for pork-producing countries. The bacterium can survive for several weeks in cold moist conditions but not under warm dry conditions. It spreads slowly, building up in numbers as the dose rate of the causal agent builds up in the environment. Pigs that recover develop a low immunity and rarely suffer from the disease again. It can be spread by other organisms (flies, mice, birds and dogs) or external mechanical factors; its main habitat is the porcine cecum and colon. It is chemotactically attracted to mucin which it penetrates with a corkscrew-like motility.
