Figure 4From: Transcriptional profiling of Actinobacillus pleuropneumoniae during the acute phase of a natural infection in pigsValidation of microarray results by qRT-PCR. Results from five up-regulated and six down-regulated genes are presented. Mean log2 ratios obtained during qRT-PCR experiments are plotted against the mean log2 ratios obtained with the microarrays. Numbers on the graph refer to the gene numbers in Additional file 2.Back to article page
