Comparison of fluorescent in situ hybridization and histological method for the diagnosis of Helicobacter pylori in gastric biopsy samples.

Abstract

FISH is a highly sensitive and specific technique for the diagnosis of H. pylori infection. It can be a method of identification when a patient is infected with coccoid forms of H. pylori. The ability of FISH for determination of clarithromycin resistance is a considerable advantage of this method over histology.
