Phenotype characterization of 11 181 invasive Neisseria meningitidis isolates collected in Brazil from 1990 to 2001 was performed. Based on laboratory data, there were 7436 (67 %) serogroup B isolates, 3391 (30 %) C, 236 W135, 51 Y, four 29E, three X, one Z, and 59 of unknown serogroup. Phenotype B : 4,7 : P1.19,15 (54 %) remained the most common during the whole of the 12-year period. Two waves were observed within the serogroup C population: the most frequent phenotype C : 2b : P1.3 (47 %) was replaced after 1998 by non-typable isolates (C : NT : NST) (16 %).
对1990年至2001年在巴西收集的11181株侵袭性脑膜炎奈瑟菌分离株进行了表型特征分析。根据实验室数据，有7436株（67%）B血清群分离株、3391株（30%）C血清群、236株W135血清群、51株Y血清群、4株29E血清群、3株X血清群、1株Z血清群以及59株血清群不明。在整个12年期间，B:4,7:P1.19,15（54%）表型仍然是最常见的。在C血清群中观察到两个波峰：最常见的C:2b:P1.3（47%）表型在1998年后被不可分型分离株（C:NT:NST）（16%）取代。
