The effect of temperature on length of time for digestion of bacteria was evaluated, by using fluorescently labeled bacteria (FLB), for phagotrophic flagellates and ciliates isolated from coastal northwest Mediterranean waters. Accumulation of FLB in protozoan food vacuoles was followed until a plateau of FLB per cell occurred; then after a 1:10 dilution of FLB with unlabeled bacteria, disappea...

The intestinal protozoan Cryptosporidium is a leading cause of diarrheal disease and mortality in young children. There currently no fully effective treatment for cryptosporidiosis, which has stimulated interest anticryptosporidial development over the last ∼10 years, with numerous lead compounds identified, including several tRNA synthetase inhibitors.

I discuss eukaryotic deep phylogeny and reclassify the basal eukaryotic kingdom Protozoa and derived kingdom Chromista in the light of multigene trees. I transfer the formerly protozoan Heliozoa and infrakingdoms Alveolata and Rhizaria into Chromista, which is sister to kingdom Plantae and arguably originated by synergistic double internal enslavement of green algal and red algal cells. I estab...

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 ...

Problem statement: Intestinal protozoan parasites are important enteropathogens in dogs. Moreover, several canine intestinal protozoan parasites are zoonotic and are considered important to public health. This study investigates the level of intestinal protozoan parasites in stray dogs, in Kerman city, Iran. Approach: Determination of the prevalence of infections was based on faecal examination...

Protozoan contamination in produce is of growing importance due to their capacity cause illnesses consumers fresh leafy greens. Viability assays are essential accurately estimate health risk caused by viable parasites that contaminate food. We evaluated the efficacy reverse transcription quantitative PCR (RT-qPCR), propidium monoazide coupled with (q)PCR, and viability staining using iodide thr...

The influence of grazing by a mixed assemblage of soil protozoa (seven flagellates and one amoeba) on bacterial community structure was studied in soil microcosms amended with a particulate resource (sterile wheat roots) or a soluble resource (a solution of various organic compounds). Sterilized soil was reinoculated with mixed soil bacteria (obtained by filtering and dilution) or with bacteria...
