WebHost specificity involves glochidia adapting to survive the immunological response of the host fish. Attached glochidia are encysted within 2–4 h (depending on temperature) by migrating cells of the host epithelial and connective tissues. Cyst formation appears to be a reparative response by fish to tissue damage caused by the glochidia. rss_formula_hybrid_2022 assetto corsaWebThe structure of a virus and how it infects a cell.
