Gill lamellae of a koi carp following infection by F. columnare. This transmission electron microscopic picture clearly demonstrates the loss of structure of the gill lamellae. The F. columnare bacteria are lining up around the remnants of these lamellae, and are closely associated with the gill epithelium (TEM, bar = 2 μm).
