Five out of 28 Great Cormorants collected in spring 2005 from the Vistula Lagoon were found to contain a total of 19 (16 in the stomach and 3 in the intestine) stage III larvae of Anisakis simplex. Spring is the season when nematode-infected herring from the western Baltic, Danish straits, and the North Sea arrive in the Vistula Lagoon and transmit the infection to cormorants feeding on them. T...

Total mercury levels in different feather types (down, contour, tail and flight) in Great Cormorants (Phalacrocorax carbo L.) were determined using CV-AAS. Feathers from Great Cormorants inhabiting the Vistula Lagoon ecosystem have an average Hg level of 7.14 ± 3.99 (μg/g w.w.). Age-dependent concentrations of Hg were statistically significant (ANOVA Kruskal-Wallis, p < 0.0001). There were also...

To assess the inducibility of avian MT genes and potential tolerability of their proteins to element exposure, we investigated the expression profiles of MT isoforms by metal accumulation in wild cormorants (Phalacrocorax carbo) and mallards (Anas platyrhynchos). We also measured transcriptional activities of avian MT genes by elements and detoxification potencies of their in vitro-expressed MT...
