Accumulation of proliferative stages (K-stages) of S. dykovae in and around blood vessels in the swimbladder; B. Magnification of K-stages showing large, multicellular structure; C. Stages of S. molnari , dispersed in different layers of the thickened swimbladder wall; D. High numbers of small S. molnari blood stages in highly vascularised area of the swimbladder; F. Buddenbrockia sp. in the gill lamellae. Scale bars: 20Â ÎĽm.
