From: Interactions of Streptococcus suis serotype 2 with human meningeal cells and astrocytes
Only S. suis serotype 2 ST1 strains induce CCL5 from infected human meningeal cells. CCL5 production from human meningeal cells infected with the S. suis strains belonging to different sequence types (STs). Results are expressed as mean ± SEM ng/ml obtained from three independent experiments. The use of different letters (a, b or c) indicates a significant difference between groups (p < 0.01). **Indicates a significant difference between N. meningitidis and the medium (p < 0.01)
