438 strains of coagula.se positive staphylococci was classified by their resistance to antibiotics and phage groups and the, results are as follows.
1. The percentage of strains resistant to respective antibiotic was highest in Group I and next in order of frequency was Miscellaneous Group including Mixed groups and Group III, with some exception.. Group 11 and non-typable were last.
2. The rate of resistant strains in respective phage group was higher among thos from healthy than sick individuals. _With,,vfry . few exceptions, but the distribution between children and adults vary according to phage groups and antibiotics.
3. Miscellaneous group including Afiieed group were predominant (41.8 per , ..cent) among strains resistant to antibiotics and next in order of frequency was Group´ I´ll-(31.5 percent), Non-typable (12.8 percent) and then Group 11 (11.4 per cent),. but Group III was predominant when Mixed groups were excluded from Miscellaneous Group. Strains belonging to Group I (2.5 per cent) were very small.
4. The antibiotic-resistant non-typable strains were much more among those from children than adults in both sick and healthy groups, and were highest with 37.0 per cent to 46.5 per cent in healthy infants.
5. The rate of Miscellaneous Group in cluding mixed and Group III was highot anmg resistant strains f ro;n suck individuals than healthy, while that, of Groups I, II 2nd.nou-typable was higher arnomg those rolthy than sick. The distribution of all these Qroups shows no marked difference between .,children and adults, except non-typ
able group.
6. 7 Out of 11 antibiotic-resitant strains belonging to Group I were isolated from healthy adults and were resistant to the antibiotics tested other than chloramphenicol and ery-
thromycin.
7. The distribution of resistant strains in Miscellaneous Group including mixed groups was predominant in Miscellaneous Group and next in order of percentage was II/III, I/III, I/Misc., I/II and I/II/III, and the other combination of groups were very small.
8. Some phage patterns showing characteristic resistant patterns to antibiotics were described.
