[Human viruses in the coastal environment of a Croatian harbor]

The authors submit the results of a survey on the viral pollution of the costal environment in the vicinity of a Croatian harbour on the northern Adriatic sea. The presence of human viruses was established in 22% of the sea water samples, 54% of the fluffy sediments samples, 44% of the sandy sediments samples and 26% of the batches of shell-fishes. Hepatitis A virus and rotavirus antigens determined by immuno-electro-osmophoresis made up 76.3% and 15.2% of the positive results respectively, whereas the coxsackieviruses, the echoviruses and the polioviruses isolated on cell culture made up 8.5% of the remaining results together. The analysis of several specimens of different nature taken simultaneously gave a better vision of the viral pollution.
