The comparison between the bacteria flora in tonsil's surface and center in patients undergone tonsillectomy

ntroduction: Chronic adenotonsillar hypertrophy is known as subclinical infection of the tonsil’s parenchyma and has various clinical presentations. The absolute cure is tonsillectomy. Since the microorganisms indwelling the central part of tonsils play an important role in chronic tonsillitis, getting to know these germs is of essential importance. This study was performed on fifty four (29 boys and 25 girls, 3-15 years old) candidates for tonsillectomy or adenotonsillectomy, referring to Ghaem Hospital through 2007-2008. The aerobes and anaerobes of the tonsil's surface and center were analyzed by smears and appropriate cultures. The most common aerobe on either the surface or centre of tonsils was Streptococus. viridans, and the next common one was Staphilococus aureous. No significant difference was observed between cultured organisms in tonsil's surface and center. Among the anaerobes gram negative cocci, (Villonella) and gram positive cocci, (Peptostreptococcus) were respectively the most common. Using appropriate techniques, we can specify much more easily the microorganisms of tonsil's center by surface sampling.
