Immune response of heifers against a Staphylococcus aureus CP5 whole cell and lysate vaccine formulated with ISCOM Matrix adjuvant
(2014-02)Staphylococcus aureus is the most frequently isolated pathogen from bovine intramammary infections worldwide. Commercially available vaccines for mastitis control are composed either of S. aureus lysates or whole-cells ... -
Immune response of heifers against a Staphylococcus aureus CP5 whole cell vaccine formulated with ISCOMATRIX™ adjuvant
(2013-02)The shortcomings of Staphylococcus aureus vaccines to control bovine mastitis have been attributed to insufficient capacity of the vaccines to induce opsonizing antibodies and to stimulate cellular immune responses. Types ... -
Immune response of Staphylococcus aureus strains in a mouse mastitis model is linked to adaptive capacity and genotypic profiles
(2017)Staphylococcus aureus is one of the most frequently isolated major pathogens from intramammary infections (IMI) worldwide. The mechanisms by which S. aureus IMI are established and maintained in dairy cows involve both ... -
Immune response to Neospora caninum live tachyzoites in prepubertal female calves
(Springer Berlin, 2019-09-04)The aim of the present study was to characterize the specific immune response in prepubertal female calves inoculated with Neospora caninum. Forty-eight N. caninum-seronegative 6-month-old Angus female calves were randomly ... -
Immunization of lambs with the S48 strain of Toxoplasma gondii reduces tissue cyst burden following oral challenge with a complete strain of the parasite
(Elsevier, 2014-09-15)This study evaluates the influence of immunizing lambs with the incomplete S48 strain of Toxoplasma gondii, on parasite dissemination following a live oral challenge with a complete strain of T. gondii (M4). Lambs were ... -
Immunization with inactivated antigens of Neospora caninum induces tolllike receptors 3, 7, 8 and 9 in maternal-fetal interface of infected pregnant heifers
(2017)Neospora caninum is an obligate parasite and a major cause of abortion in cattle. Pregnancy failures appear to be associated with weak innate defences on the maternal-fetal interface during infection with N. caninum. Herein, ... -
Immunological findings associated with Argentinean strains of Mycobacterium avium subsp. paratuberculosis in bovine models
(Elsevier, 2016-08)Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of ruminant paratuberculosis. The aim of this study was to evaluate the biological behavior of different Argentinean strains of MAP in two bovine ... -
Immunopathogenesis of bovine neosporosis throughout gestation
(College of Medicine and Veterinary Medicine, University of Edinburgh, 2013)Despite Neospora caninum being recognised as a major cause of bovine abortion, its pathogenesis is only partially understood. Evidence of immune mediated placental pathology has been reported as being responsible for ... -
Impact of a leaf-cutting ant (Atta sexdens L.) on a Pinus taeda plantation: A 6 year-long study
(Wiley, 2022-07-10)Leaf- cutting ants are the most economically important pest of plantation forests in the Neotropics. These social insects can defoliate whole trees, reducing their growth ability and occasionally causing tree mortality. ... -
Impact of a leaf-cutting ant Atta sexdens on a Pinus taeda plantation: a 6 year-long study [Conjunto de datos]
(2022)Datos obtenidos en un ensayo establecido para determinar el efecto a largo plazo de la presencia de la hormiga cortadora de hojas Atta sexdens sobre el crecimiento en diámetro y altura, mortalidad y madera comercial de ... -
The impact of agriculture on soil texture due to wind erosion
(2015-01)Wind erosion produces textural changes on topsoil of semiarid and arid environments; however, the selection of particles on different textured soils is unclear. Our objectives were to evaluate textural changes induced by ... -
Impact of agroecological management on plant diversity and soil-based ecosystem services in pasture and coffee systems in the Atlantic forest of Brazil
(Elsevier, 2021)The development of agroecosystems that can provide multiple ecosystem services with a reduced need of external inputs, requires management practices that foster ecological processes to enhance soil quality and crop ... -
Impact of closure type and storage temperature on chemical and sensory composition of Malbec wines (Mendoza, Argentina) during aging in bottle
(Elsevier, 2019-07)Malbec is the flagship variety of Argentina mainly due to its high oenological value and plasticity to obtain different wine styles. During bottled aging, the chemical and organoleptic composition of wines is subject to ... -
Impact of crop aerial and root biomass inputs on soil nitrifiers and cellulolytic microorganisms
(Elsevier, 2019)In agricultural no-till systems, crop residue management has an important impact on the activity and abundance of soil microorganisms, which play a crucial role in soil health and quality. In these systems, when cover crops ... -
Impact of Crop and Residue Management on the Physical and Chemical Stabilization of Soil Organic Matter at Farm Level
(University of Nebraska, 2011)This dissertation explores changes over time in soil organic matter (SOM) stabilization of two irrigated production fields: a continuous maize sequence that was converted from no-till to conservation deep tillage (Site 1), ... -
Impact of dairy farms on groundwater quality in a productive basin in the northeast of the Pampean Plain, Argentina
(Elsevier, 2023-11)The Pampean Plain is a relevant world food production area where livestock and agricultural activities are developed. The northeast of this region is characterized by dairy production, where large quantities of excreta ... -
Impact of elevated temperature and water deficit on the chemical and sensory profiles of Barossa Shiraz grapes and wines
(Wiley, 2015-06)Background and Aims: Interactions are the main causes of complexity in field experiments; however, no studies have combined water and temperature regimes in field‐growing vines. Here we assessed grape and wine attributes ... -
