Forty-eight isolates of and 4 isolates of were found by disc diffusion to be sensitive to colistin sulphomethate. The minimum inhibitory concentration (MIC) of colistin sulphomethate of the isolates ranged from 3·125-200 μg. per ml. The MIC was lower with a smaller inoculum, and for most strains the MIC in agar was lower than the MIC in broth. On first isolation only 48 per cent of the colistin-sensitive strains exhibited swarming at 37°, and after passage through semi-solid agar 25 per cent of the strains still did not swarm. None of the strains produced indole.
通过纸片扩散法发现，48株[具体细菌名称1]和4株[具体细菌名称2]对硫酸多粘菌素敏感。这些分离株的硫酸多粘菌素最低抑菌浓度（MIC）范围为每毫升3.125 - 200微克。接种量较小时MIC较低，并且对于大多数菌株，琼脂中的MIC低于肉汤中的MIC。初次分离时，仅48%对多粘菌素敏感的[具体细菌名称1]菌株在37°时表现出群游现象，经半固体琼脂传代后，仍有25%的菌株不群游。所有[具体细菌名称2]菌株均不产生吲哚。
