FIGURE 1. Α. Timeline of the samplings conducted in cats, for
the laboratory investigation of SARS-CoV-2 infection status. Detailed
sampling time-points are presented for C2 (top row) and C3 (bottom row).
Sampling time-points for C1 were as same to those for C2, except for the
fact that fecal swabs were not obtained on D9 and D11. Vertical arrows
indicate oropharyngeal swab (blue), fecal swab (red), and serum sampling
(green) time-points. Horizontal bars of the same colors indicate
time-periods with real-time RT-PCR-positive or ELISA-positive results.
The real-time RT-PCR-positive RNA extracts that were subjected to
next-generation sequencing are marked with an asterisk on the left of
the respective arrow. The numbering of the sampling time-points refers
to D0, i.e. Nov. 12th, the date of onset of the
owner’s clinical signs. Β. SARS-CoV-2 titers in the real-time
RT-PCR-positive oropharyngeal (blue) and fecal (red) swabs of C2 and C3,
expressed as Log10 viral RNA copies/swab. The dashed
lines indicate the limit of detection.
