Teschoviruses as indicators of porcine fecal contamination of surface water.
Teschoviruses specifically infect pigs and are shed in pig feces. Hence, their presence in water should indicate contamination with pig fecal residues. To assess this hypothesis, we have developed a real-time reverse transcriptase PCR (RT-PCR) method that allows the quantitative detection of pig teschovirus (PTV) RNA. The method is able to detect 92 fg of PTV RNA per ml of sample. Using this me...
متن کاملBovine enteroviruses as indicators of fecal contamination.
Surface waters frequently have been contaminated with human enteric viruses, and it is likely that animal enteric viruses have contaminated surface waters also. Bovine enteroviruses (BEV), found in cattle worldwide, usually cause asymptomatic infections and are excreted in the feces of infected animals in large numbers. In this study, the prevalence and genotype of BEV in a closed herd of cattl...
متن کاملIrrigation Increases Inorganic Carbon in Agricultural Soils
Inorganic C reactions are among the most important chemical reactions that occur in irrigated soils and may contribute to the total amount of C sequestered in those soils. Because CO2 can escape from soils to the atmosphere or return to precipitate carbonate minerals, soils are open systems with regard to inorganic C. We measured inorganic and organic C stored in southern Idaho soils having lon...
متن کاملPlant-parasitic nematodes in maine agricultural soils.
In a survey of plant-parasitic nematodes associated with agricultural crops in nine Maine counties, 744 soil samples from 26 potential host plants were analyzed between November 1987 and January 1989. The most commonly encountered nematode genus was Pratylenchus, occurring in 85% of the samples from most crops, except blueberries and onions. Pratylenchus penetrans and P. crenatus were found com...
متن کاملCadmium contamination of agricultural soils and crops
23 The biogeochemistry and bioavailability of cadmium, released during sphalerite 24 weathering in soils, were investigated under contrasting agricultural scenarios to assess 25 health risks associated with sphalerite dust transport to productive soils from mining. 26
