最近,我们从脑脊液涂片中观察到一些革兰氏阴性杆菌。用 Gilardi 标准法鉴定其为洋葱假单胞菌。只是在某些脑脊液中发现,而不是所有的脑脊液中都能检出。所以洋葱假单胞菌的检出可能是污染,因而我们培养了盛脑脊液的试管、染液、玻片和去离子水。在结晶紫溶液中发现了洋葱假单胞 Recently, we have observed some Gram-negative bacilli from cerebrospinal fluid smear. It was identified as Pseudomonas cepacia by Gilardi standard method. Only found in some cerebrospinal fluid, but not all cerebrospinal fluid can be detected. Therefore, detection of Pseudomonas cepacia may be contaminated, so we cultured tubes, dye baths, slides, and deionized water containing cerebrospinal fluid. In the crystal violet solution found in onion pseudocells
