Query: NC_014751:225477 Mycoplasma leachii PG50 chromosome, complete genome
Lineage: Mycoplasma leachii; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: Mycoplasma leachii, formerly Mycoplasma sp. 'bovine group 7', was originally isolated from cattle suffering from arthritis and mastitis in Australia. Mycoplasma leachii is part of the mycoides cluster like Mycoplasma mycoides SC and Mycoplasma capricolum, but it can infect both bovine and caprine hosts.
Subject: NC_019771:2816732 Anabaena cylindrica PCC 7122, complete genome
Lineage: Anabaena cylindrica; Anabaena; Nostocaceae; Nostocales; Cyanobacteria; Bacteria
General Information: Country: United Kingdom; Environment: Ponds; Isolation: Water, most likely pond, Cambridge, UK, 1939; Temp: Mesophile. They form long filaments and can be found worldwide in various aquatic environments as well as some terrestrial ones. These bacteria can form a variety of differentiated cell types, including spore-like cells (akinetes), small motile filaments (hormongia) and most importantly, heterocysts that are nitrogen-producing cells. The heterocyst produces multiple layers outside of its cell wall, shuts down photosystem II in order to inhibit oxygenic photosynthesis and ramps up metabolism in order to use up the oxygen present. Heterocysts donate fixed nitrogen compounds as amino acids to neighboring cells and in return receive a photosynthetically produced carbon source such as sucrose. These organisms produce toxic blooms in aquatic environments that are harmful or fatal to animals and humans due to the various cyanotoxins they produce.
