Peritonsillar abscess (PTA) is the most common complication of tonsillitis. Cultivation usually reveals a wide spectrum of aerobic and anaerobic microbiota. This retrospective study compared PTA incidence and the spectrum of individual microbial findings in groups of patients divided by gender, age, and season. Of the 966 samples cultivated, a positive cultivation finding was detected in 606 patients (62.73%). Cultivation findings were negative in 360 (37.27%), meaning no pathogen was present or only common microbiota was cultivated. The highest incidence of PTA was found in group I patients (19–50 years) (p ≤ 0.0001) and the most frequently cultured pathogens was Streptococcus pyogenes (36.23%). Gender seemed to have an influence on the results, with higher incidence found in males (p ≤ 0.0001). The analysis of correlation between PTA incidence and season did not yield statistically significant results (p = 0.4396) and no statistically significant differences were observed in individual pathogen frequency. PTA had a higher incidence in adult males and a slightly higher incidence in girls in childhood. The following findings are clinically significant and have implications for antibiotic treatment strategy: (1) the most frequently cultivated pathogen was Streptococcus pyogenes; (2) an increased incidence of anaerobes was proven in the oldest group (>50 years).

腹膜脓肿的流行病学和微生物学方面。

腹膜周围脓肿（PTA）是扁桃体炎最常见的并发症。耕种通常会显示出多种需氧和厌氧菌群。这项回顾性研究比较了按性别，年龄和季节划分的患者组中PTA的发生率和各个微生物发现的范围。在培养的966个样品中，有606名患者（62.73％）检测到阳性培养结果。在360处的培养结果为阴性（37.27％），这意味着不存在病原体或仅培养常见的微生物群。PTA的发生率最高组I期患者（19-50岁）（发现p ≤0.0001），最常见的病原体培养为化脓性链球菌（36.23％）。性别似乎对结果产生影响，男性发病率更高（p ≤0.0001）。PTA发病率与季节之间的相关性分析未得出统计学上显着的结果（p = 0.4396），并且在单个病原体频率上也未观察到统计学上的显着差异。儿童时期PTA的发病率较高，成年男性的发病率略高。以下发现具有临床意义，并且对抗生素治疗策略具有影响：（1）最常培养的病原体是化脓链球菌；（2）在年龄最大的年龄组（> 50岁）中，厌氧菌的发病率有所增加。
