[Phage relationships of coagulase-positive staphylococci isolated from raw and pasteurized cow's milk].
Studied is the behaviour to phages of 136 strains of coagulase positive cstaphylococci, isolated from raw (82), pasteurized milk stored in tanks (30) and pasteurized milk in bottles (24). The Staphylococcus aureus strains investigated are sensitive to bovine phages and, above all, to those of the 4th group (102, 107, 117 and 42D) or in combination with them. No lyses are established in the 1st and 3rd phage groups. The 107/117 and 107/117/42D are the phage types most frequently identified. The same phage types are found in both raw and pasteurized cow milk. It is established that 82 per cent of the Staphylococcus aureus strains studied with the rystal-violet test belong to types A and B after Meyer.
