Fig. 4

Pathogen dynamics of SGPV and ISAV-HPR0 in gill swabs with concurrent levels in water and aerosol samples. The area surrounding the curves represents the standard deviation. The black curves in the graph indicate daily mortality, with peak mortality observed following the initial peak infection. The y-axis displays the inverted mean cycle quantification (Cq) values, while the x-axis represents the study period, with day 0 marking the day when the last fish was introduced to the tanks, i.e. days post-introduction (dpi). The blue rectangle marks the partial cleaning event on the fifth sampling day (14 dpi). Cq values of 40 indicate negative results. ns: P > 0.05, *: P ≤ 0.05, **: P ≤ 0.01, ***: P ≤ 0.001, ****: P ≤ 0.0001.
