[Biochemical, physiological, and enzymatic study of 78 strains of Helicobacter (Campylobacter) pylori isolated from gastroduodenal biopsies].
A biochemical, physiological and enzymatic study of 78 C. pylori strains isolated from gastroduodenal biopsies is reported. All strains were positive in the oxidase, catalase and urease tests. 97.4% produced SH2 in the lead acetate band and 79.4% showed beta-hemolytic activity in sheep blood agar. In the antibiotic selection tests, C. pylori was characterized to be resistant to nalidixic acid and sensitive to cefalotin . The enzymatic study demonstrated the presence of acid and alkaline phosphatases. This finding and the urease test give C. pylori a define bacteriological character which differentiate it from the remaining campylobacteria.
