Percentages of antimicrobical resistance of potentially pathogenic bacterial species with more frequent isolation, in the years 1973-1976, in specimens of the respiratory tract show some statistically significant variations. From the study of these variations of resistance in the years examined it follows that too near periods should not be compared as often has been noted from one year to the next a change of their direction. In a bacterial genus or in genera often considered akin for their antimicrobical susceptibility, differences that for some drugs resulted remarkable have been emphasised.
1973 - 1976年间，呼吸道标本中分离频率较高的潜在致病细菌物种的抗菌耐药百分比呈现出一些具有统计学意义的变化。从对这些在所研究年份中的耐药性变化的研究可以看出，不应比较过于接近的时期，因为常常可以注意到从一年到下一年其变化方向会发生改变。在一个细菌属或通常因其抗菌敏感性而被认为相近的属中，已经强调了某些药物所导致的显著差异。
