1. A series of 110 patients with staphylococcal infections has been investigated. From 43 patients a penicillin-resistant staphylococcus was isolated: in cultures from 38 patients all staphylococcal colonies tested were penicillin resistant and in five both sensitive and resistant strains were isolated. Seven patients yielded a streptomycin-resistant staphylococcus.

2. Of the 84 strains of staphylococci which could be phage typed, 33 belonged to the group of phages 6/7/47 and 32 were of type 52 A. Of the 32 typable penicillin- resistant strains 18 belonged to the group of phages 6/7/47, and 13 were type 52 A.

3. Of the 115 strains isolated 110 were α-lysinogenic.

4. These results are compared with those found a year previously and the significant changes are discussed.
