ABSTRACT

Helicobacter pylori infection has been studied in 60 patients who were suffering from either a peptic ulcer disease or a gastritis complaint. Helicobacter pylori was searched in antral biopsy specimens using standard bacteriological methods (Gram-staining urea-test, culture) and histological staining techniques (hematoxylin-eosin-saffron, undifferentiated Giemsa). The culture was successful in 40 cases. The antibacterial activity of 13 malagasy medicinal plants has been tested versus Helicobacter pylori using disc method on agar culture. For five extracts, we observed an anti-Helicobacter pylori activity which would deserve further investigations.
