Figure 3From: Both flagella and F4 fimbriae from F4ac+ enterotoxigenic Escherichia coli contribute to attachment to IPEC-J2 cells in vitroExpression level of flagella and fimbriae genes in different isogenic mutants compared with WT C83902. GapA was used as the normalizing internal standard. The transcriptional expression of the detected genes was measured by qRT-PCR. *Indicates statistically significant difference when compared to the WT C83902 strain (P < 0.05). WT, wild-type.Back to article page
