Fig. 1From: Conjunctival transcriptome profiling of Solomon Islanders with active trachoma in the absence of Chlamydia trachomatis infectiona Heat map visually representing the gene expression intensity of total differentially expressed genes, (n = 7761) in each array sample. Red indicates high expression, blue indicates low expression. b Principal components analysis of differentially expressed genes in children with and without TF and Ct infection in the Solomon Islands (n = 20). Point colour indicates the clinical phenotype whilst the size of the point is proportional to the load of Ct infection in specimens within the DI groupBack to article page
