Query: NC_012985:1 Candidatus Liberibacter asiaticus str. psy62, complete genome
Lineage: Liberibacter asiaticus; Liberibacter; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Candidatus Liberibacter asiaticus causes Huanglongbing (also called citrus greening disease) in citrus in Asia. This organism causes a lethal infection to the tree and is transmitted from tree to tree by the sap-sucking Asian citrus psyllid, Diaphorina citri. Once infected the citrus tree turns yellow (huanglongbing means yellow dragon disease) and the fruit remains green.
Subject: NC_012225:2611680 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.
