From: Cattle remain immunocompetent during the acute phase of foot-and-mouth disease virus infection
Cattle infected with FMDV were viraemic during acute infection and developed neutralising antibodies. A. Onset and duration of viraemia of all six FMDV challenged cattle used in this study as obtained by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). B. Neutralising antibody titre in serum of infected cattle. Sera with titres greater than or equal to 45 were considered to be positive (dotted line).
