...It should be mentioned that mean zeta potentials and calculated interaction energies do not account for the influence of microscopic physical and chemical heterogeneity on colloid adhesive parameters [Foppen and Schijven, 2006; Duffadar and Davis, 2007, 2008; Kim et al., 2008; Metge et al., 2010]....

...The oocysts were harvested from a calf infected with the ‘‘Iowa’’ isolate of C. parvum (Dr. Harvey Moon, National Animal Disease Center, Ames, Iowa) and purified at the SPL before shipment to the USGS, (Boulder, CO) as described in Abudalo et al. (2005) and Harvey et al. (2008)....

...Other research has shown that sediment-associated metal oxide content, particularly the surface coverages of the metal oxides on the grain surfaces, is responsible for controlling virus (Pieper et al., 1997) and oocyst transport (Abudalo et al., 2005) in iron-laden quartz sand....

...Although carboxylated microspheres may be obtained that have similar buoyant densities, sizes, and aspect ratios to those of oocysts (Harvey et al., 2008), the electrophoretic mobilities can differ, depending upon the pH, age, and treatment of the oocysts (Brush et al., 1998; Butkus et al., 2003)....
