Characterization of a Pasteurella multocida bacteriophage.

The Pasteurella multocida bacteriophage B939a produces turbid plaques, which suggests infection with a temperate phage. Attempts to induce production of lytic phage by UV irradiation were unsuccessful, however, Bateriophage B932a is highly stable at 4 C and relatively stable at room temperature. It tolerates moist heat at 60 C, but is inactivated at 70 C in 10 minutes. Morphologically, it is a tailed phage with a hexagonal head.
