Medium supplementation for growth of Campylobacter pyloridis

Medium supplementation for growth of Campylobacter pyloridis.

Experiments were conducted to define the growth requirements of Campylobacter pyloridis, a newly discovered organism associated with gastritis and peptic ulcers. Two clinical isolates were streaked onto various media, and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. The growth obtained on fresh chocolate agar, composed of GC a...

Campylobacter pyloridis, gastritis, and peptic ulceration.

Campylobacter pyloridis is a spiral bacterium which was seen by histopathologists several years before it was cultured in 1982 in Perth, Western Australia. It has unique cellular fatty acids, predominantly tetradecanoic acid and cis-11, 12 methylene octadecanoic acid. It also has a unique ultrastructure which is different from that of other campylobacters. C pyloridis possesses a powerful ureas...

Susceptibility of Campylobacter pyloridis to 20 antimicrobial agents.

The susceptibility of 50 strains of Campylobacter pyloridis, isolated from human gastric biopsies, to 20 antimicrobial agents representing the different families of antibiotics was tested. The pattern of susceptibility was similar to that of the C. jejuni-C. coli group except for ampicillin, cephalothin, and rifampin. The relative resistance to cefsulodin was also noted.

Rapid identification of Campylobacter pylori (C. pyloridis) by preformed enzymes.

Campylobacter pylori (C. pyloridis) is a fastidious organism found in the gastric mucosa associated with histological gastritis and peptic ulceration. A rapid identification scheme that detects the presence of preformed enzymes (Rosco Diagnostica, Taastrup, Denmark) was applied to clinical isolates of C. pylori. The isolates tested were a very homogeneous group. They all produced oxidase, catal...
