Differential adsorption of occluded and nonoccluded insect-pathogenic viruses to soil-forming minerals

Article Abstract:

The adsorption and infectivity of one occluded and two nonoccluded viruses, Helicoverpa armigera single nucleopolyhedrovirus (HaSNVP) (Baculoviridae), Cricket paralysis virus (CrPV) (Dicistroviridae) and Invertebrate iridescent virus 6 (IIV-6) (Iridoviridae) respectively in mixtures with a choice of soil-forming minerals are compared. Results reveal that the interactions between soil-forming minerals and insect viruses appear to be most important in nucleopolyhedroviruses, followed by invertebrate iridescent viruses and least important in CrPV which might reflect the ecology of these pathogens.

Fate of pathogens present in livestock wastes spread onto fescue plots

Article Abstract:

A study was conducted to examine the decline of pathogens, which is inoculated into solid and liquid wastes generated on commercial farms. However concerns are raised that increased slurry generation as a consequence of more intensive farming practices could lead to increased survival of zoonotic agents in the environment.

Monte Carlo simulation of pathogen behavior during the sprout production process

Article Abstract:

A Monte Carlo simulation model of the sprout production process was created to determine the most-effective points for pathogen control. Factors modeled included initial pathogen concentration and prevalence, seed disinfection effectiveness, and sampling of irrigation water, or sampling of the finished product.
