Forty-nine patients (20 men and 29 women)
were investigated for Helicobacter pylori tinfection.
All patients had dyspeptic problems
and underwent gastroscopy at the Max Per-
Alta Hospital, Cartago. They were examibed
by histology (Warthin-Starry and Gimenez
stains) and cultivation as a reference
method. Helicobacter pylori strains could be
isolated from 71.4% of the patients. Altogether,
69.4% pattentes were shown to be infected
using a combination of both stains; the
Warthin-Stally stain showed 97% sensitivity
and 85.7°16 of specificity and the Gimenez
technique, 97.7% and 78.6% respectively.
The results confirm that both stains are sen-sitive methods for the detection of H. pylori
in gastric biopsies.
