The study of the immunological structure of the population in respect of intestinal yersiniosis at territories with different hydrothermal conditions has revealed the presence of a greater immune stratum (23.9% with the average agglutination titer being 1.8 +/- 0.09 log D) in humid areas, such as the region of the Upper Volga, in comparison with dry areas, such as the region of the Middle Volga, where the level of the immune stratum has proved to be twice as low (10.6% with the average agglutination titer being 0.8 +/- 0.1 log D). At both territories no essential differences in the risk of infection between the inhabitants of rural and urban areas, as well as between different professional and age groups have been revealed, with the exception of persons over 51 years of age, among whom the occurrence of seroconversions has proved to be lower.
对不同水热条件地区人群肠道耶尔森菌病免疫结构的研究表明，与干旱地区（如伏尔加河中游地区，免疫层水平低两倍，为10.6%，平均凝集效价为0.8 +/- 0.1 log D）相比，湿润地区（如伏尔加河上游地区）存在更大的免疫层（23.9%，平均凝集效价为1.8 +/- 0.09 log D）。在这两个地区，除51岁以上人群（其血清转化发生率较低）外，城乡居民以及不同职业和年龄组之间的感染风险没有本质差异。
