Fig. 2From: Oral vaccination with recombinant Lactobacillus casei expressing Aha1 fused with CTB as an adjuvant against Aeromonas veronii in common carp (Cyprinus carpio)The identification of recombinant strains. Bands indicated by blue (1038 bp) or yellow (1449 bp) were analyzed by DNA sequencing and were consistent with the putative sequences, respectively. A The PCR amplification product of recombinant strains: M: DNA ladder (bp); Lane 1–5: PCR product of Cm-resistant clones.
