BACTERIA CLOSELY RESEMBLING HELICOBACTER-PYLORI DETECTED IMMUNOHISTOLOGICALLY AND GENETICALLY IN RESECTED GALLBLADDER MUCOSA

A microorganism with close immunohistological and gene tic resemblance to Helicobacter pylori was found in the resected gallbladder mucosa o f a 41-year-old woman. The woman was admitted to hospital complaining of fever and right hypochondrial pain. Cholecystectomy was carried out under the diagnosis of gallstones and cholecystitis. A microorganism resembling H. pylori (stained with H&E, Giemsa, and Wartin-Starry) was detected incidentally on pathological examination. The microorganism was also positive for immunohistochemical staining. An amplification r eaction was seen on genetic examination by the polymerase chain reacti on (PCR) method (urease beta-genes). Our findings suggest that H. pylo ri may be present in tissues other than gastric mucosa.
