All exhibited a requirement for carbon dioxide, and only C jejuni strains NCTC 11168 and NCTC 11392 tolerated its absence (growth reduced), when the oxygen concentration was low. The studies indicated that atmospheres containing 5% to 10% oxygen and 1.0% to 10% carbon dioxide are suitable for growth of the various biotypes of thermophilic campylobacters.
25.6.2004 · Campylobacter jejuni is a predominant cause of food-borne bacterial gastroenteritis in the developed world. We have investigated the importance of a homologue of the periplasmic HtrA protease in C. jejuni stress tolerance. A C. jejuni htrA mutant was constructed and compared to the parental strain, and we found that growth of the mutant was severely impaired both at 44°C and …
Eighteen genes were identified bio- informatically as potential contributors to the differences in oxygen tolerance between strains. Among them, cj0203, cj0264c, cj0415, cj0425, cj0628, cj0629 and cj0864 were considered the top potential contributors. The oxygen tolerance of the four C. jejuni strains was differ- ent, and this tolerance ...

Campylobacter jejuni growth is strongly limited by the presence of oxygen. C. jejuni requires an oxygen tension of 2% to 10% for growth, and it is also sensitive to higher oxygen concentrations ...
1.10.2007 · The pathogen Campylobacter jejuni is considered a microaerophile yet has been shown to grow in vitro in atmospheres with partial oxygen tension of 21%. To achieve a better understanding of its microaerophily, the oxygen requirement and tolerance of four C. jejuni strains were investigated by measuring their growth under different conditions, by performing …
Campylobacter jejuni growth is strongly limited by the presence of oxygen. C. jejuni requires an oxygen tension of 2% to 10% for growth, and it is also ...
The oxygen tolerance of the four C. jejuni strains was differ- ent, and this tolerance positively correlated with their resistance to metronidazole. This study ...
2 Campylobacter have varying degrees of oxygen tolerance (3–5%) between species (Forsythe 2000). Most strains of Campylobacter do not grow in the presence of air, other than a few strains that may grow under slightly oxygen rich conditions. Optimal growth occurs at 5% oxygen and 2–10% carbon dioxide (Park 2002).
The pathogen Campylobacter jejuni is considered a microaerophile yet has been shown to grow in vitro in atmospheres with partial oxygen tension of 21%.
In the presence of oxygen, the numbers of C. jejuni were reduced by a minimum of 4.6 log10 CFU mL−1 over 21 days. When inoculated onto chicken fillets, the C ...
Technical Abstract: The human pathogen Campylobacter jejuni is considered a microaerophile, yet it has been shown to grow in vitro under atmospheres with ...
Abstract. Campylobacter jejuni is a fastidious organism, growing in microaerophilic conditions with a temperature range between 37 degrees and 42 degrees C. Multiple types of media can be used to cultivate it; however, Mueller Hinton broth and agar support the best C. jejuni growth. Optimum atmosphere for C. jejuni is 85% N2, 10% CO2, and 5% O2.
