Fig. 4From: Oral vaccination with recombinant Lactobacillus casei expressing Aha1 fused with CTB as an adjuvant against Aeromonas veronii in common carp (Cyprinus carpio)Detection of the genetic stability of recombinant L. casei strains. Bands indicated by blue (1038 bp) or yellow (1449 bp): The PCR analysis of recombinant pPG-Aha1/Lc CC16 plasmid or recombinant pPG-Aha1-CTB/Lc CC16 plasmid, respectively. M: DNA marker; Lanes 1–10: PCR amplification results of the 1 th to the 50 th generation of pPG-Aha1/Lc CC16 or pPG-Aha1-CTB/Lc CC16, respectivelyBack to article page
