(Springer, 2014-04)Neospora caninum is a protozoan parasite known as an important cause of bovine abortion worldwide. Little is currently known about how different strains of N. caninum vary in their pathogenicity. In this study, we compared ... -
Pathology of cattle experimentally intoxicated with ground Ricinus communis seeds
(Brazilian Association of Veterinary Pathology, 2018-11)Five Aberdeen Angus calves were inoculated intra-ruminally with ground seeds of Ricinus communis at doses of 1, 1.5, 2 or 3 gr per kg of body weight, or with saline solution (control), respectively. Grossly, all intoxicated ... -
Patterns of resource use efficiency in relation to intra-specific competition, size of the trees and resource availability in ponderosa pine
(Elsevier, 2014-01-15)Patterns of resource use efficiency (RUE) in relation to intra-specific competition, size of the trees and resource availability are under debate. Also, the relationship between RUE and growth efficiency (GE) seems to be ... -
Penetration by Botryosphaeriaceae species in avocado, guava and persimmon fruit during postharvest
(Wiley, 2021-11-05)Botryosphaeriaceae species have a wide host range and a worldwide distribution. These fungal species can colonize several plant organs, such as the trunk, leaves and fruit. Some Botryosphaeriaceae species cause important ... -
Persistence of tall fescue in a subtropical environment : tiller survival over summer in response to flowering control and nitrogen supply
(Wiley, 2016)Enhancing pasture persistence is crucial to achieve more sustainable grass-based animal production systems. Although it is known that persistence of perennial ryegrass is based on a high turnover of tillers during late ... -

(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Imazapir es un herbicida de amplio espectro de control, perteneciente al grupo químico de las imidazolinonas. En Argentina es aplicado a gran escala en los cultivos de girasol y maíz Clearfield. Debido a su acción residual ... -
Pest control treatments with phosphine and controlled atmospheres in silo bags with different airtightness conditions
(2016)La tecnología de bolsas de silo ha sido ampliamente utilizada en Argentina para almacenar granos (por ejemplo, trigo, maíz, cebada, girasol y soja, entre otros) desde mediados de los años noventa. Bolsa de silo son ampliamente ... -
Phenotypic characterisation of the cellular immune infiltrate in placentas of cattle following experimental inoculation with Neospora caninum in late gestation
(BMC, 2013-07)Despite Neospora caninum being a major cause of bovine abortion worldwide, its pathogenesis is not completely understood. Neospora infection stimulates host cell-mediated immune responses, which may be responsible for the ... -
Phenotypic characterization of immune cells in fetal tissues of cattle immunized and challenged with Neospora caninum
(Elsevier, 2019-11)The purpose of this work was to characterize the cellular phenotype in inflammatory infiltrates of fetal tissues from pregnant heifers immunized and experimentally challenged with Neospora caninum. Fetuses from 20 heifers ... -
Phosphorus placement effects on phosphorous recovery efficiency and grain yield of wheat under no-tillage in the Humid Pampas of Argentina
(2014)No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P, grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations ... -
