Abstract (EN): Specimens of Sardina pilchardus (n=90) obtained in a fish market of north of Portugal were examined for the presence of Kudoa spores in the muscle. Number of spores per gramme of muscle tissue was determined and the muscle texture was assessed by digital pressure and recorded as normal or soft. The morphology and morphometric characteristics of the spores are consistent with those reported for Kudoa thyrsites. The prevalence of infection was high (85.7%) and the intensity varied widely being 1.57x10(6) spores per gramme of muscle the highest value observed. Thirty percent of the fish specimens presented soft flesh and a significant positive correlation was obtained between proportion of specimens with soft flesh and abundance of spores.
