Phage DNA isolated from temperate bacteriophages of P. multocida. Varying amounts of DNA were recovered from different isolates (PM122 and PM336) and, in some cases (PM86), two DNA bands were present. Two bands of DNA were isolated from five P. multocida isolates (PM86, PM172, PM486, PM934 and PM954) and suggested the presence of more than one phage type
