Previously found DNA sequence (iam), correlated with the invasiveness of Campylobacter strains, became a starting point for present investigation. Main goal of this study was to isolate number of Campylobacter strains from chicken carcasses, to determine their taxonomic position and to establish the presence of iam sequence in their genoms. It was found, that invasion associated marker is present in all Campylobacter coli strains and in majority but not all Campylobacter jejuni. This may confirm the idea that the marker is not only responsible for diarrhea in humans but also may be important in the colonization of chicken guts.
先前发现的与弯曲杆菌菌株侵袭性相关的DNA序列（iam），成为了当前研究的起点。本研究的主要目标是从鸡 carcasses 中分离出多个弯曲杆菌菌株，确定它们的分类地位，并确定其基因组中iam序列的存在情况。研究发现，侵袭相关标记存在于所有空肠弯曲杆菌菌株以及大多数（但并非全部）结肠弯曲杆菌中。这可能证实了这样一种观点，即该标记不仅与人类腹泻有关，而且在鸡肠道定植中可能也很重要。
