Rates of digestion of bacteria by marine phagotrophic protozoa: temperature dependence.
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...
متن کاملImportance of passive diffusion in the uptake of polychlorinated biphenyls by phagotrophic protozoa.
Unicellular protozoan grazers represent a size class of organisms where a transition in the mechanism of chlorobiphenyl (CB) introduction, from diffusion through surface membranes to ingestion of contaminated prey, could occur. This study compares the relative importance of these two processes in the overall uptake of polychlorinated biphenyls by protists. Uptake rates and steady-state concentr...
متن کاملDifferential rates of digestion of bacteria by freshwater and marine phagotrophic protozoa.
Differential decreases over time of two bacterial species, Escherichia coli and Enterococcus faecalis, in a freshwater and a marine ecosystem were observed and explained by a differential rate of digestion of these bacteria by phagotrophic flagellates and ciliates. For this purpose, fluorescence-labeled bacteria (FLB) were used and prepared from the two species cited above. The number of FLB wa...
متن کاملGenetic Engineering of Trypanosoma (Dutonella) vivax and In Vitro Differentiation under Axenic Conditions
Trypanosoma vivax is one of the most common parasites responsible for animal trypanosomosis, and although this disease is widespread in Africa and Latin America, very few studies have been conducted on the parasite's biology. This is in part due to the fact that no reproducible experimental methods had been developed to maintain the different evolutive forms of this trypanosome under laboratory...
متن کاملUrinary excretion of creatinine of children under different nutritional conditions.
I N 190S, Shaffer’ demonstrated that the daily excretion of creatinine in adult man is remarkably constant over long periods of time, even under the most varied circumstances. Because the quantity excreted is little affected by diet, exercise or volume of urine, the daily creatinine excretion is used to determine the completeness of twenty-four hour urine collections. Since creatinine excretion...
