Chesapeake Organisms

Spreading mechanism for pathogens to which sufficient throughout the world is caused by ballast water transports. Sea-going vessels unintentionally transport foreign organisms across the seas. Most of the animal or vegetable blind passengers’ travel in the sea water carried to the stabilization in the ballast tanks and when loading and unloading in the port waters. But while the spread of non-native species of plankton, jellyfish or shells on the ballast water has long been known, so far ignored the global dissemination of viruses and bacteria in this way. Spreading mechanism for pathogens to which sufficient throughout the world is caused by ballast water transport,”scientists report from the Smithsonian Environmental Research Center (SERC), the center of marine biotechnology, of the Institute of biotechnology of the University of Maryland and Old Dominion University.

Gregory Ruiz of the SERC, head of the research group says, that he and his colleagues in their investigations in the Chesapeake, located south of the U.S. capital of Washington High concentrations of microorganisms, pathogenic bacteria and viruses found Bay. Including the causative agent of cholera (Vibrio cholerae), which was discovered in all ships. Despite increasing warnings prior to the invasion of foreign organisms and the resultant consequences are largely unknown”extent and potential impact of the transfer of micro-organisms, Ruiz and his colleagues say. No one knows how the micro-organisms evolve, when they get to their new Habitat”. The Federal Environmental Agency in German ports investigations each year around 2.2 million tonnes of ballast water from non-European regions to be drained. On average, they found roughly 1 individual per gallon of ballast water, resulting in a possible entry of the organism by 6 million individuals per day in German waters.

Most of the 200 studied ships came from tropical and warm temperate seas. Among the proven foreign organisms two scourge algae genera (Alexandrium and Gonyaulax), which were also poison producing Types include. One way to minimize the number of organisms in ballast water, the water exchange on the high seas with a water depth of over 2 000 meters, as would be it also envisages a policy of the International Maritime Organisation. Continue heating, filtration or chemical processes are being discussed, but still not mature. Due to their strong tolerance to high temperatures and its ability to make extremely robust permanent moulds, invasions of microorganisms can be so hard to stop”, says Gregory Ruiz. The spread of bacteria and viruses could be well one of the most insidious problems of ballast water exchange”.
