Evaluación de antígenos recombinantes en la prueba de interferón gamma en bovinos tuberculosos no reactores a la prueba tuberculínica
(Asosiación Argentina de Veterinarios de Laboratorios de Díagnóstico, 2018-11)La tuberculosis se encuentra presente en rodeos bovinos de nuestro país, impactando a nivel de los sistemas de producción de cría y lecheros por disminuir la eficiencia productiva de los animales infectados e imponer ... -
Evaluation of a virulent strain of Mycobacterium avium subsp. Paratuberculosis used as a heat-killed vaccine
(Elsevier, 2021-11)Bovine paratuberculosis is one of the most important chronic infectious diseases in livestock. This disease is difficult to control because of its inefficient management (test and cull strategy and inadequate biosecurity). ... -
Evaluation of different heterologous prime-boost immunization strategies against Babesia bovis using viral vectored and protein-adjuvant vaccines based on a chimeric multi-antigen
(2016)Protection against the intraerythrocytic bovine parasite Babesia bovis requires both humoral and cellular immune responses. Therefore, tailored combinations of immunogens targeted at both arms of the immune system are ... -
Evaluation of different nitrogen sources on growth and fermentation performance for enhancing ethanol production by wine yeasts
(Elsevier, 2023-12)The utilization of grape juice from low oenological value grape varieties for bioethanol production represent an alternative for diversification and value addition in viticulture. Optimizing Very High Gravity (VHG) ... -
Evaluation of hydrolytic enzyme activities from digestive fluids of Anthonomus grandis (Coleoptera: Curculionidae)
(Wiley, 2020-08)The cotton boll weevil, Anthonomus grandis, is a major pest of cotton crops in South America. In this work, partial biochemical characterizations of (hemi) cellulases and pectinases activities in the digestive system (head‐ ... -
Evaluation of hydrothermal and alkaline pretreatment routes for xylooligosaccharides production from sugar cane bagasse using different combinations of recombinant enzymes
(Springer, 2023-10)Xylan is the most abundant constituent of hemicellulose fraction of lignocellulosic biomass. Short xylooligosaccharides (XOS), obtained via xylan hydrolysis, have well-known prebiotic and antioxidant properties that are ... -
Evidence of Ehrlichia chaffeensis in Argentina through molecular detection in marsh deer (Blastocerus dichotomus)
(Elsevier, 2019-04)Vector-borne pathogens are responsible for serious emerging diseases and have been widely described in wildlife. Ehrlichia chaffeensis causes the zoonotic “monocytic ehrlichiosis” in humans, is transmitted by the tick ... -
Expanding the benefits of Tnt1 for the identification of dominant mutations in polyploid crops: A single allelic mutation in the MsNAC39 gene produces multifoliated alfalfa
(Frontiers Media, 2022-04)Most major crops are polyploid species and the production of genetically engineered cultivars normally requires the introgression of transgenic or gene-edited traits into elite germplasm. Thus, a main goal of plant research ... -
Experimental selection of long‐term intracellular mycobacteria
(Wiley, 2014-09)Some intracellular bacteria are known to cause long‐term infections that last decades without compromising the viability of the host. Although of critical importance, the adaptations that intracellular bacteria undergo ... -
