Patent ID: 8852613

Claim:
A method of preparing a one phase aqueous composition comprising a Mycoplasma hyopneumoniae bacterin, an acrylic acid polymer in a concentration range between 0.8 and 1.2 mg/ml, a pharmaceutically acceptable carrier, and substantially no oil; comprising: a. cultivating a M. hyopneumoniae whole cell culture such that the Mycoplasma hyopneumoniae bacterin has an antigen amount of at least 3 log 10 per ml; b. inactivating the M. hyopneumoniae whole cell culture; c. isolating an immunizing amount of a Mycoplasma hyopneumoniae bacterin; d. admixing an acrylic acid polymer in the concentration range between 0.8 and 1.2 mg/ml; and e. admixing a pharmaceutically acceptable carrier.
