1. 866 strains of staphylococci which had been isolated ten years ago and stocked without transplan-tation, were inoculated in Brainheart infusion broth. There were 187 strains of coagulase positive and 133 coagulase negative still surviving. The 187 coagulase positive strains were compared with the 100 strains isolated from suppurative lesions, in 1961 in regard to phage group and drug resistance. As the results of phage typing of 187 strains, the strains belonging to phage group I were less in number than phage group III or untypable group. We had observed no change in each phage pattern. Of the strains in 1961, there were considerably numerous strains having multiple resistance to antibiotics, (PC, SM, TC, EM, CP, KM.). It was observed that the type 80/81 was agreed with the drug resistance at the limit of 107./ml of HgC12. The staphylococcus strains stocked for 10 years had less drug resistance and did not show so clear relation to the type 80/81. 2. We have examined the resistance against desication of the representative 3 strains in each phage, groups through 4 seasons. group I was more resistant than any other group in every seasons.
