Overland Transport of Rotavirus and the Effect of Soil Type and Vegetation
Soil and vegetation are two critical factors for controlling the overland transport kinetics of pathogens in a natural environment. With livestock operations moving more towards concentrated animal operations, the need to dispose of a very large amount of manure in a localized area is becoming increasingly important. Animal manure contains a substantial amount of microbial pathogens, including ...
متن کاملOverland and near-surface transport of Cryptosporidium parvum from vegetated and nonvegetated surfaces.
Understanding microbial pathogen transport patterns in overland flow is important for developing best management practices for limiting microbial transport to water resources. Knowledge about the effectiveness of vegetative filter strips (VFS) to reduce pathogen transport from livestock confinement areas is limited. In this study, overland and near-surface transport of Cryptosporidium parvum ha...
متن کاملModeling Transport of Cryptosporidium Parvum Oocysts in Overland Flow
Cryptosporidium, a manure-borne protozoan parasite that is common in the environment, has recently been recognized as an important microbial contaminant of water. Cryptosporidium parvum (C. parvum) can cause infection and diarrhea in many mammalian hosts, including humans. Because cattle, particularly calves, are considered a major source of C. parvum , it is important to understand the movemen...
متن کاملCryptosporidium parvum transport from cattle fecal deposits on California rangelands
Cryptosporidium parvum is a fecal borne protozoan parasite that can be carried by and cause gastrointestinal illness in humans, cattle, and wildlife. The illness, cryptosporidiosis, can be fatal to persons with compromised immune systems. At question is the potential for C. parvum in cattle fecal deposits on rangeland watersheds to contaminate surface water. First, C. parvum oocysts must be rel...
متن کاملTransport, fate, and infectivity of Cryptosporidium parvum oocysts released from manure and leached through macroporous soil
A major mode of transmission of Cryptosporidium parvum, a widespread waterborne pathogen, is via contaminated drinking and recreational waters. Oocyst transport to surface water can occur by deposition of manure directly in the water or by wash off in surface runoff. Oocyst transport to groundwater is less straightforward and requires that the oocysts move through soil and bedrock to reach the ...
