Infants and toddlers attending ten day-care facilities in closed communities in southern Israel were tested monthly for pharyngeal carriage of Streptococcus pyogenes and associated respiratory morbidity. Overall, the prevalence of Streptococcus pyogenes was 2.7% in infants and 8.4% in toddlers, reaching 8.5% and 17.8% in the two groups, respectively by midwinter. In 4 of 61 (6.6%) infants and 15 of 67 (22.4%) toddlers, the organism was recovered in more than one month (range 2 to 5 months). Streptococcus pyogenes in the pharynx was only associated with rhinitis during the spring and summer but not with other respiratory symptoms. During the study period, a mean of 0.9 strains were isolated in day-care facilities attended by infants, while a mean of 2.1 strains were found in toddlers. Young children attending day-care facilities show early acquisition of Streptococcus pyogenes in the pharynx.
对以色列南部封闭社区中10所日托机构的婴幼儿每月进行一次检测，以检查其咽部A组链球菌携带情况及相关呼吸道疾病发病率。总体而言，婴幼儿咽部A组链球菌携带率分别为2.7%和8.4%，到冬季中期，两组携带率分别升至8.5%和17.8%。61名婴儿中有4名（6.6%）、67名幼儿中有15名（22.4%）在超过1个月的时间里（2至5个月）检测到该病菌。咽部A组链球菌仅在春季和夏季与鼻炎有关，与其他呼吸道症状无关。在研究期间，婴儿所在日托机构平均分离出0.9株病菌，幼儿所在机构平均分离出2.1株病菌。在日托机构的幼儿咽部较早出现A组链球菌。
