Abstract: In acute and subacute cases of swim bladder inflammation (SBI) of common carp fry, numerous protozoa were demonstrated by histopathological examination. These parasites can be observed in the swim bladder approximately for 10 days, and a causal relationship can be established between them and the inflammatory process. The protozoa (Myxozoa) were easiest to follow in the tunica interna of the anterior sac of the swim bladder, in its loose connective tissue, and the most severe lesions developed also here. In acute swim bladder inflammation, no bacteria were demonstrable. The accompanying bacterial infections were responsible for the more severe lesions characteristic of the chronic stage on inflammation.
