title: Typing coagulase-positive staphylococci of different origin with Blouse and Meekins' phages.
abstract: Making use of four experimental Blouse and Meekins' (I) phages 06, 40, 58, and 93, derived from Staphylococcus intermedius strains of canine origin, 631 strains of three coagulase-positive staphylococcal species were typed. The typability was in a great extent dependent on the origin of the tested strains. Of 310 S. aureus strains 23 (7%) at RTD and 45 (15%) at 100 X RTD were typable, all without exception of C biotype from cows and sheep. Of 281 S. intermedius strains 208 (74%) at RTD and 14 (5%) at 100 X RTD were lyzed with the above-mentioned I phages. The typability of the isolates in the nine groups from buzzards, pigeons, rooks, dogs, wild ducks, pheasants, foxes, horses, and mink ranged from 59 to 90%. No special relationship was recorded between the origin of the strains and the phage patterns. When testing 135 S. hyicus subsp. hyicus strains nearly one fifth (19%) of them were typable, for the most part at RTD. On the contrary, all 36 S. hyicus subsp. chromogenes strains were resistant to the used phages. The usefulness of the I phages for classificatory aims was discussed.
