Intensity and incidence of pathogens and lesions measured at the semi-quantitative scale in mussels from San Jorge Bay, northern Chile. Squares represent intensity of lesion/pathogen; white = no lesion, light colour = low, medium colour = moderate, dark colour = severe. VLPs = virus-like particles, BC-Ct = brown cells in the connective tissue, HI = haemocytic infiltration in the connective tissue.
