Distribution of oxytetracycline resistance plasmids between aeromonads in hospital and aquaculture environments: implication of Tn1721 in dissemination of the tetracycline resistance determinant Tet A

Article Abstract:

Results demonstrate dissemination of tetracycline resistance-encoding plasmids between aeromonads and Escherichia coli and between human and aquaculture environments. Oxytetracycline mesophilic aeromonads collected from hospital effluents and from a fish farm served as models.

Prevalence and molecular characterization of tetracycline resistance in Enterococcus isolates from food

Article Abstract:

A study of the phenotypic and genotypic assessment of tetracycline (TC) resistance in a collection of 187 Enterococcus food isolates mainly originating from European cheeses is presented. In addition, a subset of tet genes belonging to the tet(M) group, transferred by in vitro filter conjugation to E.faecalis recipient strain JH2-2 are further characterized by partial sequencing to examine the degree of nucleotide polymorphism and their sequence similarities to previously determined tet(M) genes.

Complete nucleotide sequence of the conjugative teteracycline resistance plasmid pFBAOT6, a member of a group of IncU plasmids with global ubiquity

Article Abstract:

The first complete nucleotide sequence of an IncU plasmid, pRFBAOT6 that is isolated from a strain of Aeromonas caviae from Westmorland General hospital effluent is presented. Putative replication, maintenance and transfer functions are identified and are located in a region in the first 31kb of the plasmid.
