Supplementary Figure 1. Blood T (CD3+; A), T CD4+ (B) T CD8+ (D) and B (CD21+, D) lymphocytes proliferation (median with interquartile range) after incubation of peripheral blood mononuclear cells with medium only (unstimulated basal), the mitogens Concanavalin A (Con-A) and Phytohemagglutinin M-form (PHA-M) and distinct Staphylococcal and Mammaliicoccal strains, and the interleukin-17A (IL-17A; E) and interferon (IFN)-γ (F) (median with interquartile range) of the supernatant of peripheral blood mononuclear cells after incubation with medium only (unstimulated basal) and the distinct staphylococci species and strains in 18 dairy cows. SA IMI: Staphylococcus aureus isolated from a persistent intramammary infection; SA nose: Staphylococcus aureus isolated from a nose; SC “IM”: Staphylococcus chromogenes isolated from a persistent intramammary infection; SC “TA”: Staphylococcus chromogenes isolated from the teat apex; and MF: Mammaliicoccus fleurettii (MF) isolated from sawdust. *P < 0.05.
