We conducted a prospective study to determine the correlation between the presence or absence of Helicobacter pylori on the tonsillar surface and in the tonsillar core as determined by the Campylobacter-like organism (CLO) rapid urease enzyme test. Our study population was made up of 55 patients who underwent adenoidectomy, tonsillectomy, or both from December 2002 through April 2003 at Khalili Hospital in Shiraz, Iran. Of these 55 patients, 45 (82%) were positive and 10 (18%) were negative for H pylori colonization as determined by CLO testing. Analysis of samples obtained from individual patients revealed differences in H pylori colonization between tonsillar surface samples and the core tissue samples. Of 106 tonsils obtained from 53 patients who underwent adenotonsillectomy or tonsillectomy, H pylori was found on 56 tonsillar surface samples (53%) and 24 tonsillar core samples (23%); only 13 tonsils (12%) contained H pylori both on the surface and in the core. We conclude that a surface swab is neither specific nor sensitive as an indicator of the presence or absence of H pylori colonization in tonsillar core tissue.
