The presence of integrons in 85 multiresistant German isolates of the predominating Salmonella enterica subsp. enterica serovar Paratyphi B dT(+) clone was investigated. All isolates possessed a chromosomally located Tn7-like class 2 integron carrying the same dfrA1-sat1-aadA1 array of gene cassettes. Only four isolates (4.7%) revealed an additional class 1 integron with two strains each containing the aadA1 or dfrA1-aadA1 gene cassettes.
对85株来自德国的多重耐药性肠炎沙门氏菌亚种肠炎血清型副伤寒B dT(+)克隆的分离株进行了整合子检测。所有分离株均含有一个位于染色体上的Tn7样2类整合子,携带相同的dfrA1-sat1-aadA1基因盒阵列。只有4株分离株(4.7%)显示存在另外一个1类整合子,其中两株各含有aadA1或dfrA1-aadA1基因盒。
