| Summary: | A recombinant Listeria monocyogenes mutant expressing green fluorescent protein (GFP) gene was constructed by homologous recombination. The target gene gfp was fused to the actA gene fragment downstream of its promoter and signal sequence. PCR amplification and restriction digestion of the PCR product confirmed the insertional fusion. The reporter gene was expressed as shown by fluorescent microscopy and SDS-PAGE/western blotting. The recombinant strain exhibited reduced invasiveness to the in vitro cultured cells as well as decreased virulence to the chicken embryos and mice. The strain has potential applications in microbe-host interaction studies in the medical or veterinary medical fields and in food microbiological studies. |
