Query: NC_016510:2426150 Flavobacterium columnare ATCC 49512 chromosome, complete genome
Lineage: Flavobacterium columnare; Flavobacterium; Flavobacteriaceae; Flavobacteriales; Bacteroidetes; Bacteria
General Information: Isolated in 1987 from a skin lesion of a brown trout fry in France. Fish pathogen. Purified genomic DNA obtained from ATCC 49512 F. columnare is considered ubiquitous in the warmwater aquatic environment, and it is the causative agent of columnaris disease in fish. Columnaris disease is common throughout the world and infects most species of freshwater fish, including aquaculture species, wild fish populations, and ornamental fish.
Subject: NC_009879:141000 Rickettsia canadensis str. McKiel, complete genome
Lineage: Rickettsia canadensis; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This organism was originally isolated from ticks in a field study on tick-transmitted diseases of small mammals in Canada. Member of the typhus group of Rickettsiales. Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Rickettsia canadensis was originally thought to be a member of the typhus group of Rickettsiales, however, it is now thought to represent a distict group with the rickettsia.
