Identification and Characterization of Cefotaxime Resistant Bacteria in Beef Cattle
Fig 4
Caption:Phylogenetic analysis of the resistance genes.
(A and B) Neighbor-joining trees from the phylogenetic analysis of the 23 isolates that contained the β-lactamase genes. bla TEM (A) and bla CTX-M (B) demonstrate the similarity of the β-lactamase genes to clinical isolates from human infections. (C) The sequences of the 16S ribosomal RNA from the same isolates were used to identify the genus and species of the cefotaxime resistant bacteria and show their sequence similarity. Asterisks indicate a human clinical isolate KCJ1409.
