Genome Sequence of Streptococcus agalactiae Strain 09mas018883, Isolated from a Swedish Cow

We announce the complete genome sequence of Streptococcus agalactiae strain 09mas018883, isolated from the milk of a cow with clinical mastitis. The availability of this genome may allow identification of candidate genes, leading to discovery of antigens that might form the basis for development of a vaccine as an alternative means of mastitis control.
