Fig. 5: Absence of a linear correlation between virus decay and the presence of each type of protease.

A, B Distribution of viral decay according to the proteolysis diameter (mm) measured for each bacterial isolate A on casein agar and B on gelatin agar. C, D Distribution of viral decay according to the quantitative protease activity measured in CFS by fluorescence (nmol/min/mL) C using a general activity kit and D using an MMPs specific kit. Red vertical lines represent the average protease activity measured by each assay. The kernel density is represented from yellow to red, indicating low to high density of data points, respectively.
