Tonsillar Crypts and Bacterial Invasion of Tonsils: A Pilot Study
نویسنده
چکیده
Objective: To investigate histologically if a lack of protection of the deep lymphoid tissue in tonsillar crypts by an intact epithelial covering is an aetiological factor for tonsillitis. Method: A prospective histological study of the tonsillar crypt epithelium by immunostaining for cytokeratin in 34 consecutive patients undergoing tonsillectomy either for tonsillitis or tonsillar hypertrophy without infection (17 patients

Anatomical evidence of microbial biofilms in tonsillar tissues: a possible mechanism to explain chronicity.
CONTEXT Bacteria within biofilms are resistant to host defenses and antibiotics. The presence of bacterial biofilms within the tissue and crypts of inflamed tonsils may explain the chronicity and recurrent characteristics of some forms of tonsillitis. OBJECTIVE To determine if microbial biofilms occur within clinically abnormal tonsils. DESIGN In this study, we evaluated the histomorphologi...
متن کاملActinomyces denticolens colonisation identified in equine tonsillar crypts
Recently, submandibular abscesses associated with Actinomyces denticolens have been reported in horses. The actinomycotic clumps have been observed in the tonsillar crypts. The aim of this study was to demonstrate colonisation of A denticolens in equine tonsils. Twelve equine tonsils obtained from a slaughterhouse were divided into two parts for histopathological examination and for isolation o...
متن کاملSelection of indicators for tonsillectomy in adults with recurrent tonsillitis
BACKGROUND We aimed to find some new indicators for tonsillectomy (TE) in adults with recurrent tonsillitis (RT) by exploring whether the frequency of tonsillitis episodes and the length of morbidity period are associated with the macroscopic signs of sclerotic process in tonsils and microbiological data assessed by culture, molecular (PCR) and transmission electron microscopy (EM) methods. M...
متن کاملDetection of group A Streptococcus in tonsils from pediatric patients reveals high rate of asymptomatic streptococcal carriage
BACKGROUND Group A Streptococcus (GAS) causes acute tonsillopharyngitis in children, and approximately 20% of this population are chronic carriers of GAS. Antibacterial therapy has previously been shown to be insufficient at clearing GAS carriage. Bacterial biofilms are a surface-attached bacterial community that is encased in a matrix of extracellular polymeric substances. Biofilms have been s...
