Figure 1From: Growth of Helicobacter pylori in a long spiral form does not alter expression of immunodominant proteinsAtypical and classic H. pylori morphology. Gram-stained slides were prepared from a broth culture of H. pylori ATCC 43504 (A), or a plate culture of H. pylori ATCC 43579 (B). Slides were examined and photographed with a 63× objective. Atypical long spiral forms were seen in broth culture, while organisms displaying classic H. pylori morphology were seen in cultures grown on solid media.Back to article page
