Two nonstaining tests for the Gram reaction, the KOH and vancomycin disk (5 micrograms) tests, were employed on 488 strains of aerobic gram-negative and gram-positive rods. Since each test may yield false results with certain species, the use of a combination is suggested.
对488株需氧革兰氏阴性菌和革兰氏阳性杆菌进行了两种用于革兰氏反应的非染色试验,即氢氧化钾(KOH)试验和万古霉素纸片(5微克)试验。由于每种试验对某些菌种可能产生假结果,因此建议联合使用。
