IMMUNIZATION OF DAIRY CATTLE WITH GAPC PROTEIN AGAINST STREPTOCOCCUS INFECTION

摘要

The GapC plasmin binding protein genes of Streptococcus dysgalactiae (S. dysgalactiae), Streptococcus agalactiae (S. agalactiae), Streptococcus uberi s (S. uberis), Streptococcus parauberis (S. parauberis), and Streptococcus ini ae (S.iniae) are described, as well as the recombinant production of the GapC proteins therefrom. Also described is the use of the GapC proteins from thos e species in vaccine compositions to prevent or treat bacterial infections in general, and mastitis in particular.
