Time course of FeLV infection in cat #261. A) FIV transmembrane (TM) specific antibody levels as determined by ELISA. B) Total anti-FeLV antibodies (black squares) and anti-FeLV p45 antibodies (black triangles) as determined by ELISA. C) Plasma FeLV p27 antigen levels as determined by ELISA. D) FeLV provirus loads as determined by real-time PCR. Two samples, indicated by asterisks, were positive for FeLV by non-quantitative PCR. Time points of FIV infection (at the age of 17 weeks), FeLV vaccinations (41 weeks, 4 years) and FeLV exposure with FeLV-A/Glasgow-1 (59 weeks) are indicated.
