“…Sorensen et al [20] studied [20]. The microbiological findings were similar to those from previous reports on peritonsillar abscess [3,6,8,9]. The antibiotic regimen most commonly prescribed (third-generation cephalosporin plus clindamycin) was active against all cultured microorganisms.…”

A total of 112 patients were studied, with a mean age of 24 years. There were no events of sepsis, and there were only four cases (3.6%) of postoperative bleeding, two of which resolved spontaneously. Only 29% of the patients required morphine pump-based analgesia in the postoperative period. The mean length of hospital stay was 3.4 days. Among the 28 unilateral tonsillectomies, 4 (14.2%) developed streptococcal tonsillitis and 2 (7.1%) were readmitted with a contralateral peritonsillitis: one cellulitis and one abscess that required drainage and tonsillectomy. The most frequently isolated microorganisms were gram-positive bacteria (Streptococcus pyogenes and other streptococci) and anaerobic bacteria (mainly Bacteroides spp. and Fusobacterium nucleatum).

“…Patients usually present with severe throat pain, fever, drooling, foul breath, trismus, neck swelling, and altered voice resonance. Microbiological findings for peritonsillar abscesses include both aerobic and anaerobic components [3,[5][6][7][8]. The aerobic bacterium Streptococcus pyogenes is isolated in nearly a third of cases [1].…”

“…However, in the work carried out by Snow et al [15], 72.3 % of patients proved to have monomicrobial infection. Also, Megalamani et al [14] identified monomicrobial growth in 65 % of their aerobic cultures. In our work, monomicrobial growth in PTA cultures predominated as well.…”

“…The majority of abscesses are polymicrobial infections, with three bacteria regarded to be key causative pathogens: Streptococcus pyogenes , Fusobacterium necrophorum and Streptococcus milleri group [1, 4, 7, 10–13]. Monomicrobial infections, however, have been reported as well [14, 15]. Management protocols are lacking, and treatment methods include needle aspiration, surgical drainage or quinsy tonsillectomy combined with antimicrobial therapy [5, 16, 17].…”

The purpose of this investigation was to explore the epidemiology, clinical history and microbiology of peritonsillar abscess (PTA). A retrospective review of PTA cases treated at the Department of Otolaryngology, Regional Specialist Hospital in Radom, Poland between 1st October 2003 and 30th September 2013 was undertaken. A total of 111 PTA patients were admitted. The study population consisted of 57.7 % males and 42.3 % females, with an average age of 31.0 (range 5–78) years. Smokers comprised 22.0 % of the study group. The seasonal variation of PTA was statistically insignificant (p = 0.45). Recurrent tonsillitis occurred in 35.5 % of patients. In comparison with the rest of the study population, patients with a history of recurrent pharyngotonsillitis had higher incidence of previous PTA episodes [odds ratio (OR) 17.8, 95 % confidence interval (CI) 2.1–148.7, p = 0.001]. Also, they were more frequently treated with antibiotics prior to hospitalisation (OR 4.6, 95 % CI 2.0–10.9, p = 0.0005) and had significantly longer hospital stay (p = 0.03). Bacterial cultures of abscess aspirates were performed in 40.5 % of patients. Monomicrobial growth was detected in 77.8 % of aerobic cultures. Streptococcus pyogenes, growing most frequently in monoculture, was found in 28.9 % of aerobic cultures. PTA patients with and without recurrent pharyngotonsillitis differed with regard to clinical history and course of disease. The percentage of smokers among PTA patients was lower than that described in the literature. Monomicrobial growth predominated in PTA aspirate cultures. S. pyogenes proved to be the most frequent pathogen.

“…We think that our relatively low rates of anaerobes cultures may be due to inappropriate sampling (by swabs for example). Considering the high percentage of anaerobes and the fact that recurrent peritonsillar abscess is more common in patients infected with anaerobes we therefore strongly recommend the use of antibiotics effective both against aerobic and anaerobic bacteria in the pediatric population [18].…”
