Mycoplasma agalactiae PG2

Names Mycoplasma agalactiae PG2
Accession numbers NC_009497, NC_013948
Background Mycoplasmas contain the smallest known genomes of any independently viable bacterial species. They have no cell wall and evolved from Firmicutes via massive genome reduction.They occur mainly as external parasites, although some can invade their host cells. Little evidence for horizontal gene transfer has been found thus far in Mycoplasma. M.agalactiae is responsible for contagious agalactia in sheep and goat, a syndrome that includes mastitis, pneumonia, and arthritis and that is also caused by some members of the mycoides cluster. In M.agalactiae about 18% of the genes have been horizontally transferred to or acquired from mycoplasmas of the mycoides cluster that are phylogenetically distant while sharing common ruminant hosts.
