Bacteriophages in Helicobacter (Campylobacter) pylori

Abstract
Bacteriophages in different stages of maturation were found in thin sections of a clinical isolated of Helicobacter (Campylobacter) pylori. Mature phage heads measured 70 .times. 60 nm and the tail at least 120 nm. Lysogeny was maintained during subculture on blood agar for more than 3 months after isolation from a gastric biopsy.
