Název v původním jazyce

Combined exposure to cyanobacterial biomass, lead and the Newcastle virus enhances avian toxicity

Popis výsledku v původním jazyce

Under environmental conditions, wild birds can be exposed to multiple stressors including natural toxins, anthropogenic pollutants and infectious agents at the same time. This experimental studywas successful in testing the hypothesis that adverse effects of cyanotoxins, heavymetals and a non-pathogenic immunological challenge combine to enhance avian toxicity. Mortality occurred in combined exposures to naturally occurring cyanobacterial biomass and lead shots, lead shots and Newcastle vaccination aswell as in single lead shot exposure. Mostly acute effects around day 10 were observed. On day 30 of exposure, there were no differences in the liver accumulation of lead in single and combined exposure groups. Interestingly, liver microcystin levels wereelevated in birds co-exposed to cyanobacterial biomass together with lead or lead and theNewcastle virus. Significant differences in body weights between all Pb-exposed and Pb-nonexposed birds were found on days 10 and 20. Single exposure
