A total of 102 Hafnia alvei clinical strains isolated from different patients with diarrhea has been tested, using polymerase chain reaction and dot-blot hybridization, for the enteropathogenic Escherichia coli attaching and effacing A (eaeA) gene to establish their role as a causative agent of diarrhea in our environment. None of them was positive for the eaeA gene. We cannot consider the eaeA gene as the virulence-associated factor implicated in the H. alvei strains isolated from diarrheal feces in our region.

在西班牙阿拉贡的腹泻患者中，Hafnia alvei中未发现eaeA基因。

已经使用聚合酶链反应和斑点杂交对从不同腹泻患者中分离出的102 株Hafnia肺炎临床菌株进行了测试，以证明其与肠道致病性大肠埃希氏菌的结合和消灭A（eaeA）基因的作用，从而确定其作为甲型肝炎的病原体的作用。我们环境中的腹泻。他们都没有对eaeA基因呈阳性。我们不能认为eaeA基因是与我们地区腹泻粪便分离出的H. alvei菌株有关的毒力相关因子。
