Figure 6From: Mycoplasma synoviae induces upregulation of apoptotic genes, secretion of nitric oxide and appearance of an apoptotic phenotype in infected chicken chondrocytesConcentration of NO in culture media of CCH infected with M. synoviae for 24, 48 and 72 h. NO concentration was determined by the Griess assay. The results are presented as mean concentrations ± standard error for two independent experiments with three replicates each. Different letters above columns indicate significant differences between NO concentrations (Student t-test, p ≤ 0.01).Back to article page
