Delayed type hypersensitivity induced by intradermal inoculation of a Neospora caninum tachyzoite antigen in previously exposed cattle
(Elsevier, 2019-01)The aim of this study was to evaluate delayed type hypersensitivity (DTH) induced by the intradermal inoculation of a Neospora caninum tachyzoite soluble lysate in cattle previously exposed with the protozoa. Four experimental ... -
Delayed-type hypersensitivity skin test against Neospora caninum in heifers with undetectable specific antibodies
(Elsevier, 2020-07-19)Delayed-type hypersensitivity (DTH) has been used in human and veterinary medicine as a skin testing for evaluating in vivocell-mediated immune responses (CMIR). Whereas CMIR is a key process to control intracellular ... -
Delimitación de ambientes edáficos en suelos de la pampa deprimida mediante la conductividad eléctrica aparente y la elevación
(2015)Los suelos de la Pampa Deprimida presentan una elevada heterogeneidad espacial. Por ende, una alternativa para el manejo de los mismos podría ser la incorporación de las técnicas de manejo por ambientes (MA). Por ello, ... -
Delimitación de zonas de manejo en pasturas bajo diferentes niveles de nitrógeno y épocas del año.
(Asociación Argentina de la Ciencia del Suelo, 2021-07)Los suelos ganaderos presentan una elevada heterogeneidad que provoca variabilidad en la producción de forraje. Por lo tanto, los objetivos de este trabajo fueron (a) determinar, a escala de lote, si la relación entre la ... -
Delineation of management zones to improve nitrogen management of wheat
(2015-01)Site-specific management of N (NSSM) is an attractive and intuitive approach to increasing N fertilizer use efficiency (NUE) of agricultural systems by adjusting fertilizer rates to the soil characteristics. The objective ... -
Delineation of management zones with soil apparent electrical conductivity to improve nutrient management
(Elsevier, 2013-11)Site-specific management demands the identification of subfield regions with homogeneous characteristics (management zones). However, determining subfield areas is difficult because of complex correlations and the spatial ... -
Denitrification in a Soil under Wheat Crop in the Humid Pampas of Argentina
(Scientific Research, 2014-09)The need to accurately estimate gaseous nitrogen losses from soils is required to have a better understanding of the processes involved as well as soil and environmental conditions, and management practices contributing ... -
Density surface modeling of European hare in the Argentinean Pampas
(Springer, 2022-01-14)The European hare (Lepus europaeus) is a game species with high economic importance for being one of the main exports of wildlife products in Argentina. However, it is also considered an agricultural pest. This study aimed ... -
Detección de serovares de Salmonella en terneros de crianza artificial de la región lechera Mar y Sierras, Argentina
(Elsevier, 2019-01-09)La salmonelosis es una de las enfermedades bacterianas que afectan el tracto digestivo de los terneros y provocan en ellos diarrea. Con el objetivo de estudiar la prevalencia de los distintos serovares de Salmonella en ... -
Detection methods and characterization of bovine viral diarrhea virus in aborted fetuses and neonatal calves over a 22-year period
(Springer, 2020-05-16)Detection of bovine viral diarrhea virus (BVDV) in aborted fetus samples is often difficult due to tissue autolysis and inappropriate sampling. Studies assessing different methods for BVDV identification in fetal specimens ... -
Detection of Plasmopara halstedii in sunflower seeds: A case study using molecular testing.
(Elsevier, 2021-05-06)Plasmopara halstedii (Farl.) Berl. & De Toni causing downy mildew of sunflower is responsible for considerable economic losses worldwide. Because P. halstedii can be seed-transmitted, monitoring of seeds for pathogen ... -
Determinación de residuos de imazapir en suelos de Argentina mediante cromatografía líquida de alta resolución y espectrometría de masas
(2013)La extracción y cuantificación de residuos de herbicidas en el suelo resultan de gran importancia para monitorear su presencia y minimizar el riesgo de contaminación asociado al uso de los mismos. Los objetivos de este ... -
Determining Mehlich-3 and DTPA extractable soil zinc optimum economic threshold for maize
(Wiley, 2020-09-16)Maize (Zea mays L.) is one of the most susceptible crops to zinc (Zn) deficiency. However, in much of the world, soil Zn tests are poorly calibrated, and thus determining a critical soil test, level for Zn is challenging. ... -
Developing integrated crop knowledge networks to advance candidate gene discovery
(Elsevier, 2016-12)The chances of raising crop productivity to enhance global food security would be greatly improved if we had a complete understanding of all the biological mechanisms that underpinned traits such as crop yield, disease ... -
