Water- borne protozoan parasitic infections

Parasitic food-borne and water-borne zoonoses.

Estimates suggest that almost half of the population of the world is affected by water-borne and food-borne infections. Parasitic food-borne and water-borne zoonoses contribute to this statistic by inflicting a heavy toll on human health and causing serious direct and indirect losses to the agricultural industry. The inability of non-industrialised countries to keep pace with population growth,...

Different regulatory mechanisms in protozoan parasitic infections.

The immune response to the protozoan pathogens, Leishmania spp., Trypanosoma spp. and Plasmodium spp., has been studied extensively with particular focus on regulation of the immune response by immunological mechanisms. More specifically, in diseases caused by parasites, immunosuppression frequently prevents immunopathology that can injure the host. However, this allows a small number of parasi...

The Roles of Mast Cells in Parasitic Protozoan Infections

Protozoan parasites such as Plasmodium spp., Leishmania spp., Trypanosoma spp., and Toxoplasma gondii are major causes of parasitic diseases in both humans and animals. The immune system plays a critical role against protozoa, but their immune mechanism remains poorly understood. This highlights the need to investigate the function of immune cells involved in the process of parasite infections ...

Osmoregulation in the parasitic protozoan Tritrichomonas foetus.

Tritrichomonas foetus was shown to undergo a regulatory volume increase (RVI) when it was subjected to hyperosmotic challenge, but there was no regulatory volume decrease after hypoosmotic challenge, as determined by using both light-scattering methods and measurement of intracellular water space to monitor cell volume. An investigation of T. foetus intracellular amino acids revealed a pool siz...
