From: The spontaneously produced lysogenic prophage phi456 promotes bacterial resistance to adverse environments and enhances the colonization ability of avian pathogenic Escherichia coli strain DE456

Figure 7

Deletion of phi456 leads to decreased type I fimbriae and adhesion ability. Transmission electron microscopy images of DE456 (A) and DE456Δphi456 (B). The red arrow points to the I fimbria, while the blue arrow points to the flagella. C Quantification of genes related to type I fimbriae by qRT-PCR. The relative expression level of fimA and fimH in the DE456Δphi456 was compared to WT. The quantification of the target gene was performed by normalizing to the reference gene dnaE. D Adhesion assay. Values are the average of three independent experiments. The error bars indicate standard deviations. Student’s t-test was used to analyse the data.
