| Since the nineteenth century ships have been using ballast water (BW) for safety, stability, propulsion and maneuverability, as well as to redress loss of fuel weight and water consumption, and to maintain structural stress at acceptable levels. Ballast water has been spreading many non-native species around the globe, but little is known about the extent and potential significance of ship-mediated transfer of microorganisms. The global movements of ballast water by ships create a long-distance dispersal mechanism for human pathogens that may be important in the worldwide distribution of microorganisms, as well as for the epidemiology of waterborne diseases. Only a few studies have been carried out on this subject, most of them involving ballast water... |

| Due to important economic activities along the French oastline, the introduction of noxious organisms into French coastal waters, particularly by ship ballast water, may have serious consequences. After preliminary studies of ship movements in Charente Maritime, several samplings of ballast water and sediment were made. Samples were taken in five major harbours in France, along the Atlantic, Channel and Mediterranean coastlines. The main task of this first assessment was the research for exotic and possibly noxious phytoplancton. Clostridium and Vibrio bacteria were also tested for. The results are presented and discussed, with plans for further work. |

| The Port Complex of Maranhão (PCM) is the second largest port complex in Brazil, receiving ships with large volumes of ballast water. To evaluate the microbiological quality of its waters, physicochemical parameters (pH and salinity), the number of coliforms (thermotolerants and totals), and the presence of enterobacterias and diarrheagenic Escherichia coli strains were analyzed. In order to identify the presence of E. coli virulence genes target regions of the stx, elt, est, aggR, CVD432, ipaH and eae nucleotide sequences were studied. The presence of totals and thermotolerants coliforms were positive. Analyzing the salinity parameter, a significant increase in total coliforms was observed during the rainy season. We identified the species Escherichia... |

| Billions of tons of ballast water are lreased world-wide every year. Living marine, brackish or freshwater organisms, including those noxioux or unwanted, can travel by that way from a part of the world to another. A successful introduction needs : 1) survival during the pumping process 2) survival in ships' ballasts 3) survival and repreoduction in the new environment. To assess the survival conditions in ship's ballasts, a small scale pilot system has been built (MARTOB project), more realistic than laboratory vials and easier to handle than a real ballast. Bacteria and phytoflagellates coming from ship's sampling or from cultures were introduced in the system ; their survival in several waters or sediments are studied, a useful method to assess the... |
