NOS2 and infection: Beside these common markers, some genes were modulated in animals acutely infected by specific strains: Tnf was downregulated by X10 infection, Nos2 for X10 and VFRA, Arg1 for Esm and 10R, while infection with CM17 and Sc43 strains did not lead to modulation of Tgfb1 gene expression (Table S4).
