Abstract Aquatic plants have high effectiveness in removing organic and inorganic contaminants, heavy metals. Eichhornia crassipes Enydra fluctuans are both popular Vietnam, with fast growth no need to take care of because these two easily live the natural environment. The focus this study was on utilization treat metals water. research conducted healthy, young from Selection qualifying that ma...

Gelatinous polymers including extracellular polymeric substances (EPSs) are fundamental to biophysical processes in aquatic habitats, including mediating aggregation processes and functioning as the matrix of biofilms. Yet insight into the impact of these sticky molecules on the environmental transmission of pathogens in the ocean is limited. We used the zoonotic parasite Toxoplasma gondii as a...

The number of Sarcocystis species that infect sea otters (Enhydra lutris) is unknown. Sea otter tissues were recently shown to harbor sarcocysts of S. neurona and of unidentified species of Sarcocystis. Whereas sarcocysts of S. neurona have walls 1-3 microm thick with type 9 villar protrusions, ultrastructure of a distinct thin-walled sarcocyst (0.5-0.7 microm thick) lacking villar protrusions,...

Sarcocystis neurona is an important cause of neurological disease in horses (equine protozoal myeloencephalitis, EPM) and sea otters in the United States. In addition, EPM-like disease has been diagnosed in several other land and marine mammals. Opossums are its only definitive hosts. Little genetic diversity among isolates of S. neurona from different hosts has been reported. Here, we used 11 ...
