Beta-hemolytic streptococci (BHS) are the most common causative agents of perianal streptococcal dermatitis (PSD). This study evaluates the distribution of BHS isolates in perianal bacterial cultures. We retrospectively reviewed microbiological results for perianal BHS that were isolated in our laboratory between 2006 and 2015. We identified a total of 105 BHS isolates from rectal swabs and swabs of clinically intact perianal skin. The majority of BHS were of group A (GABHS) (73/105; 69.5%), followed by group B BHS (GBBHS) (27/105; 25.7%), and non-group A or B BHS (5/105; 4.8%). The distribution of GABHS was age-specific, with the majority of GABHS obtained from young children. All BHS isolates were susceptible to penicillin. GABHS were universally susceptible to clindamycin, whereas 1.4% were resistant to erythromycin. GBBHS were resistant to erythromycin and clindamycin in 14.8% and 7.4% of cases. In addition, we wanted to emphasize the importance of correct diagnosis of PSD. Hence, we provide a review of protocols that can decrease the time to diagnosis and treatment of PSD, reduce patients' discomfort, and prevent unnecessary diagnostic procedures.
β-溶血性链球菌（BHS）是肛周链球菌性皮炎（PSD）最常见的病原体。本研究评估了肛周细菌培养中BHS分离株的分布情况。我们回顾性分析了2006年至2015年在我们实验室分离出的肛周BHS的微生物学结果。我们从直肠拭子和临床完整的肛周皮肤拭子中总共鉴定出105株BHS分离株。大多数BHS为A组（GABHS）（73/105；69.5%），其次是B组BHS（GBBHS）（27/105；25.7%），以及非A组或B组BHS（5/105；4.8%）。GABHS的分布具有年龄特异性，大多数GABHS分离株来自幼儿。所有BHS分离株均对青霉素敏感。GABHS对克林霉素普遍敏感，而对红霉素耐药的占1.4%。GBBHS对红霉素和克林霉素的耐药率分别为14.8%和7.4%。此外，我们想强调正确诊断PSD的重要性。因此，我们提供了一份方案综述，该方案可以缩短PSD的诊断和治疗时间，减轻患者的不适，并避免不必要的诊断程序。
