Abstract:In this paper,the detection of helicobacter pylori infection was performed on gastric mucosa obstained from biopsies of 95 patients undergoing endscopy for various upper gastrointestinal diseases.Helicobacter pylori infection was detected by methods including bacteria culture,urease test,direct smear,hematoxylin and eosin staining,Giemsa staining and modified Warthin-Starry staining,The positive valuse of the above methods was 63.2%,69.5%,60.1%,58.9%,71.6%,74.7%,respectively.The results showed that the modified Warthin-Starry stain was the most sensitive among the above methods,while hematoxylin and eossin staining showed the lowest positive value (P<0.05).Sensitivity and specificity of the urease test and Giemsa staining was the higher (P>0.05).Urease test combined with direct smear has an advatage in ease,lower cost,rapidity,sensitivity and sepcificity for the detection of Helicobacter pylori.
