Complete Genome Sequences of Two Phage-Like Plasmids Carrying the CTX-M-15 Extended-Spectrum ß-Lactamase Gene.

Two similar phage-like plasmids carrying CTX-M-15 resistance cassettes were identified from two environmental Escherichia coli isolates. They demonstrate strong nucleotide sequence identity to the phage-like plasmid pECOH89 and Salmonella bacteriophage SSU5.

AnCo3, a New Member of the Emerging Family of Phage-Like Plasmids.

A phage-like plasmid isolated from a clinical isolate of Salmonella enterica serovar Derby has strong nucleotide sequence identity to the phage-like plasmids pSTM_phi isolated from Salmonella enterica serovar Typhimurium L495, AnCo1 and AnCo2 from Escherichia coli 243 and Escherichia coli 244, and the virulent Salmonella-specific SSU5 bacteriophage.
