Provided are a recombinant protein for producing a swine Mycoplasma infection-preventing vaccine composition, and a swine Mycoplasma hyopneumoniae and Mycoplasma hyorhinis infection-preventing vaccine composition including the recombinant protein. When the recombinant proteins for the vaccine production in accordance with the present disclosure are added to the swine Mycoplasma infection-preventing vaccine composition, the immune response to the swine Mycoplasma hyopneumoniae and swine Mycoplasma hyorhinis strain and the immune response to the P97 protein are increased. As a result, the present vaccine exhibits a defensive effect superior to an existing commercially available vaccine. Therefore, the recombinant proteins for the vaccine production according to the present disclosure and the vaccine compositions using the recombinant proteins may effectively prevent diseases caused by the Mycoplasma hyopneumoniae and Mycoplasma hyorhinis infection, especially, swine Mycoplasma-derived pneumonia and swine Mycoplasma-derived arthritis.

This invention provides a protein-A or protein-G treated Mycoplasma hyopneumoniae (M.hyo) antigen that is compatible with antigens from other swine pathogens, wherein the M.hyo antigen is an M.hyo culture supernatant.

This invention relates to methods and compositions for binding antibodies. The methods may be used to isolate antibodies, treat disorders related to excess antibodies, acutely block antibodies to stop an autoimmune or inflammatory response, and inhibit neutralizing antibodies. In embodiments, the invention relates to methods of inhibiting neutralizing antibodies against a heterologous agent when the heterologous agent is administered to a subject, comprising administering to the subject an effective amount of Mycoplasma protein M or a functional fragment or derivative thereof, thereby inhibiting neutralization of the heterologous agent. The invention further relates to modified Mycoplasma protein M or functional fragments thereof having increased thermostability relative to wild-type protein M and their use in the methods of the invention.

The present invention provides proteins that are suitable to be used as the active ingredient in subunit vaccine against Mycoplasma spp. The present invention also provides a subunit vaccine made therefrom. Said proteins have been experimentally proved to have the capability of inducing sufficient immune response to avoid pigs from Mycoplasma spp. infection. Said vaccine may have one of said proteins as active ingredient; or may have two or more of said proteins and is formulated as a cocktail vaccine. The present vaccine not only is safer than the conventional vaccines but also has equal or even better immune efficiency than the conventional ones. Furthermore, fusion partners suitable for producing said proteins of high solubility are also proved, which can significantly reduce production cost.
