Cytotoxicity of fish cell lines exposed to Veronaea botryosa. White sturgeon skin (WSSK-1) (A) and epithelioma papulosum cyprini (EPC) (B) cell lines were exposed to high (10:1), medium (1:1) and low (1:10) spore concentration and incubated at 15, 20 and 25 °C. Error bars shown as 95% CI. There is a significant difference (p < 0.001) when comparing the percent cytotoxicity in all concentrations of spore:cell ratio except when comparing 10:1 vs 1:1 at 15 °C for EPC cell line (p = 1). There is also a significant difference (p < 0.001) between the different temperatures, except when comparing 15 °C vs 20 °C at the 1:10 spore:cell ratio for the EPC cell line (p = 0.467).
