Streptococcal diseases, namely, acute glomerulonephritis and acute rheumatic fever, are common features in the aboriginal population of the Northern Territory of Australia. We examined the group A streptococcal M types identified during various surveys conducted since 1987. Streptococci were predominantly isolated from skin infections. A high proportion of the isolates could not be serotyped by conventional means and were designated M nontypeable (MNT). M-specific DNA sequences from the MNT isolates were examined, and sequence types were proposed for the classification of MNTs. This allowed a more precise estimate of the M types present in a population study.
链球菌疾病，即急性肾小球肾炎和急性风湿热，是澳大利亚北领地原住民的常见病症。我们研究了自1987年以来在各项调查中鉴定出的A组链球菌M型。链球菌主要从皮肤感染中分离出来。很大一部分分离株无法通过传统方法进行血清分型，被指定为M非型（MNT）。对MNT分离株的M特异性DNA序列进行了检测，并提出了序列类型用于MNT的分类。这使得在人群研究中能够更精确地估计存在的M型。
