Statement on Availability and Uses of Staphylococcal Phage Typing

Staphylococci and Their Classification

“…There is evidence that phage-typing correlates with disease potential. However, phage typing is of no value in epidemiological studies (Borman, 1959). Thus, as stated by Wentworth (1963): "it appears that the ability to produce toxins and enzymes correlates much better with the clinical sources of cultures than with their phage susceptibility."…”

PHOSPHATASE ACTIVITY OF STAPHYLOCOCCUS AUREUS : CORRELATION OF ENZYME PRODUCTION WITH RESISTANCE TO PENICILLIN AND PHAGE PATTERN

“…Of 322 of the 595 staphylococcal isolates in the present series that were found to pho-sphatae be resistant to a 2-unit or a 10-unit penicillin d (0.05 M)-disc, only 38 % had a phosphatase activity of 400 f4.0 through or over. These strains are tabulated in Table 1 inomethane-according to phage groups, the number in each 7.08 through category that were resistant to penicillin, and the number of resistant strains that had a high phos- The proportions of high phosphataseand low phosphatase-producing staphylococci in the three main phage groups (Borman et al, 1959) and among various strains not belonging to these groups are shown in Fig. 4.…”
