Abstract
Lysogenicity in chicken coagulase-positive staphylococci was tested by incubating the strains in the presence of mitomycin C. Of 88 strains tested, 84 (95.5%) were phage carriers and 81 were susceptible to any of the phages. The lysogenic strains were detected with almost equal frequency from typable and untypable strains by the international phages. Sixteen phages (CH phages) were isolated from chicken lysogenic strains, and their usefulness for the typing of chicken staphylococci was evaluated. Of 122 strains examined, 101 (82.8%) were typable with the CH phages at a routine test dilution (RTD). About 82% of strains untypable by the phages of the international series were lysed by 1 or more of the CH phages. The phages seemed to be highly specific to chicken staphylococci, because they lysed only a few strains of animal origin other than chicken. Thus, the 16 phages newly established had significant advantages in typing chicken strains.
