title: Stability of immune potency of tylosin 1-killed, broth-propagated Hemophilus gallinarum bacterin.
abstract: Immunizing potency of broth-propagated Hemophilus gallinarum (HG)bacterin was compared with tylosin and thimerosal treatment as the HG-inactivation agent and preservative. The immunizing potency of a tylosin-treated HG bacterin was as stable as a thimerosal-treated bacterin after 53 months storage at 2 to 5 degrees C.
