Vibrio parahaemolyticus and V. alginolyticus, marine foodborne pathogens, were treated with UVC-radiation (240 J/m2) to evaluate alterations in their outer membrane protein profiles. Outer membrane protein patterns of UVC-irradiated bacteria were found altered when analyzed by sodium dodecyl sulphate polyacrylamide gel electrophoresis. Altered proteins were(More)
Vibrio parahaemolyticus and Vibrio alginolyticus were subjected to γ-irradiation (0.5 kGy) or starvation by incubation for 8 months in seawater to study modifications in their outer membrane protein patterns. After treatment, outer membrane protein profiles of starved or γ-irradiated bacteria were found to be altered when analyzed by sodium dodecyl sulfate(More)
In this study, an Aeromonas hydrophila identified as a denitrifying bacterium by PCR detection of nitrate reductase (narG) and nitrite reductase (nirK) genes was incubated in seawater microcosms for 8 months at room temperature and at 4 °C. A study of the phenotypic variation demonstrated that A. hydrophila becomes gelatinase-positive after the incubation(More)
Salmonella is an international foodborne pathogen widely disseminated in seawater that regularly causes large outbreaks of food poisoning. In this study, we have investigated the effect of starvation on the ability of Salmonella enterica serovar Typhimurium cells to adhere to polystyrene microplate and Hep2 cells in seawater microcosms after incubation for(More)
The survival of bacteria in natural environments is of practical importance. In this study, we investigated the effect of starvation on the survival and adhesion ability of Shigella in domestic treatment plant effluent microcosms after incubation at either room temperature or 4°C for 1 month. Our results showed that the number of cells decreased(More)
In this study, we incubated four strains of Staphylococcus aureus for 8 months in seawater microcosms. The biofilm formation on microplates and on glass and the surface hydrophobicity of starved cells were investigated. Our results showed that the stressed cells increased their hydrophobicity from 12 to 44% and also their capacity for producing biofilm.(More)
In this study, we investigated the survival, adhesion and the morphology of Shigella after its incubation in various concentrations of salts. Our results showed that, after 48 h of incubation, the rate of cell survival is inversely proportional to the increase of salinity of the medium. In addition to that, the results prove the evidence that the(More)
Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of a hydatid heart cyst or the opening of a visceral hydatid cyst (often in the liver) into the venous circulation. We report two cases of hydatid pulmonary embolism following rupture of a hydatic cyst in the right ventricle. One case progressed to chronic cor pulmonale. We(More)
