Abstract
Experiments were conducted to define the optimal constituents of culture medium and atmospheric condition for growth of Campylobacter pylori. Two clinical isolates were streaked onto various media, incubated in two different atmospheric conditions (microaerophilic condition and carbon dioxide incubator), and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. The growth obtained on Campy media, composed of GC agar base plus 1% hemoglobin, 0.2% activated charcoal, 1% IsoVitaleX, vancomycin 6mg /L nalidixic acid 20mg/L and amphotercin 2 mg/L, was used as reference. Our conclusions were as follows: Tryptic soy agar base was not acceptable for the growth of C. pylori. The organism grew in both atmospheric conditions, but generally showed a scantier growth in the carbon dioxide incubator than under the microaerophilic condition, however GC agar containing 1% hemoglobin and 0.2% activated charcoal supported well the growth of C. pylori in the carbon dioxide incubator. The authors have found that the GC agar base supplemented with 1% hemoglobin and 0.2% charcoal was the most satisfactory medium and a microaerophilic condition was optimal atmospheric condition for the growth of Campylobacter pylori in this study.
