ONLINE COVER Mucosal IgT Earns Its Stripes. This month's cover features a pair of rainbow trout (Oncorhynchus mykiss) out for a swim. Immunoglobulin T (IgT) is the specialized mucosal antibody of teleost fish, including trout. In this issue, Xu et al. report that temporary depletion of trout IgT led to dysbiosis of the gill bacterial community and increased susceptibility to infection by a mucosal parasite.
