Fig. 1From: The virulence factor ychO has a pleiotropic action in an Avian Pathogenic Escherichia coli (APEC) strainRelative fold expression levels of ychO verified using quantitative Real Time-PCR (qRT-PCR). (a) Expression of ychO in SEPT362 in the spleen and lungs after 24 and 48 h post infection compared to expression in vitro using LB media. (b) In vitro analysis of ychO expression in the SEPT362, ΔychO and complemented strains grown in DMEM mediumBack to article page
