本研究的目的是确定婴幼儿链球菌菌群中不同链球菌种类的患病率和比例。本文对18例婴幼儿在出牙前和出牙后的口腔粘膜和牙槽嵴进行口腔拭子采集60份口腔样本。主要根据Kilian等人最近修订的生化标准，在唾液链球菌琼脂上发现了549株菌株。无论是在流行率（89%）还是在每个样本中回收的口腔链球菌比例（中位数= 87%的链球菌菌群）上，1型链球菌都占主导地位。唾液链球菌也很常见（94%），但通常只占总链球菌菌群的一小部分（中位数= 3%）。口腔链球菌和血管链球菌在大约三分之一的有牙状和有牙状的婴儿中被检测到。出牙前未检出血链球菌，但在7/14的患儿中检出血链球菌。因此,S。有丝分裂体是幼小婴儿最初定植的链球菌菌群的主要组成部分。
The objective of this study was to determine the prevalence and proportions of different streptococcal species among the streptococcal flora during infancy. A total of 60 oral samples were collected by oral swabbing of the buccal mucosa and alveolar ridges of 18 infants before tooth eruption and from buccal and lingual surfaces of teeth after tooth eruption. A total of 549 isolates on mitis salivarius agar were speciated, principally by recently revised biochemical criteria of Kilian et al.Streptococcus mitisbiovar 1 predominated, both in prevalence (89%) and proportion of oral streptococci recovered in each sample (median = 87% of streptococcal flora).Streptococcus salivariuswas also prevalent (94%) but generally represented a small percentage of the total streptococcal flora (median = 3%).Streptococcus oralisandStreptococcus anginosusstrains were detected in approximately one third of predentate and dentate infants in the first year of life.Streptococcus sanguisstrains were not detected before tooth eruption, but could be detected in 7/14 of the infants with teeth. Thus,S. mitisconstitutes the major component of the initially colonizing streptococcal microbiota of the young infant.
