Growth on media containing 1.5% NaCl is one of the criteria for phenotypical differentiation of Campylobacter laridis from other thermophilic Campylobacter spp. Campylobacter isolates from birds and Campylobacter type strains could be adapted to growth at 3% NaCl within 19 to 72 subsequent passages on nutrient agar with increasing salt contents. The acquisition of salt-tolerance was stable after ten passages on media without salt and did not induce changes in other phenotypical characteristics. The results of slide agglutination demonstrate changes in the antigenic pattern of the Campylobacter strains after growth in salt. Heat-labile and heat-stable antigens of the salt-tolerant variants of Campylobacter type strains differed from those of the parent strains.
在含有1.5%氯化钠的培养基上生长是从其他嗜热弯曲菌属中表型区分拉氏弯曲菌的标准之一。从鸟类分离出的弯曲菌菌株和弯曲菌模式菌株在营养琼脂上随着盐含量增加进行19至72次传代后，能够适应在3%氯化钠条件下生长。在不含盐的培养基上传代十次后，耐盐性的获得是稳定的，并且没有引起其他表型特征的变化。玻片凝集试验结果表明，弯曲菌菌株在盐中生长后抗原模式发生了变化。弯曲菌模式菌株的耐盐变体的热不稳定和热稳定抗原与亲本菌株不同。
