Ninety two strains of isolated from hospitalized patients were phage grouped and phage typed and their resistance pattern to methicillin were studied. Forty five (48.9%) strains were nontypable, followed by mixed group in 23 (25%). The phage groups I, II, III, V and miscellaneous groups were 3.3 per cent, 7.6 per cent, 8.7 per cent, 1 per cent and 3.3 per cent respectively. Majority of the strains were methicillin resistant. Out of 45 nontypable strains 33 (73.3%) were methicillin resistant whereas in mixed phage group methicillin resistance was found in 52 per cent. The inadequacy of available phages for typing, rising incidence of methicillin resistance in untypable strains and variance of phage group and phage types at various places has been highlighted.
对从住院患者中分离出的92株菌株进行了噬菌体分组、分型，并研究了它们对甲氧西林的耐药模式。45株（48.9%）菌株无法分型，其次是混合组，有23株（25%）。噬菌体I组、II组、III组、V组和其他组分别占3.3%、7.6%、8.7%、1%和3.3%。大多数菌株对甲氧西林耐药。在45株无法分型的菌株中，33株（73.3%）对甲氧西林耐药，而在混合噬菌体组中，甲氧西林耐药率为52%。突出了现有分型噬菌体的不足、无法分型菌株中甲氧西林耐药率的上升以及不同地区噬菌体组和噬菌体类型的差异。
