Results are expressed a BTV RNA copy number per 100 mg of tissue.
No positive detection could be found in any tested sample in BTV2 and BTV4 vaccinated or non-vaccinated groups.
NV_: non vaccinated group; V_: vaccinated group; NEG: negative result; Mesent. LN: mesenteric lymph node; Prescap. LN: prescapular lymph node.
