Seed-transmitted Epichloë sp. endophyte alleviates the negative effects of head smut of grasses (Ustilago bullata) on Bromus auleticus
(2017)Some grasses are co-infected by ‘castrator’ fungal pathogens, such as Ustilago bullata, and beneficial seed transmitted Epichlo€e endophytes that compete for plant photosynthates and flowers. Epichlo€e-infected (E+) and ... -
Primary production of lowland natural grasslands and upland sown pastures across a narrow climatic gradient
(2017-04)Variation in aboveground net primary production (ANPP) is usually studied across wide environmental gradients focusing on spatial averages of zonal natural communities. We studied the spatial and temporal variation of ANPP ... -

Using APAR to Predict Aboveground Plant Productivity in Semi-Arid Rangelands: Spatial and Temporal Relationships Differ
(2018)Monitoring of aboveground net primary production (ANPP) is critical for effective management of rangeland ecosystems but is problematic due to the vast extent of rangelands globally, and the high costs of ground-based ... -
Prevalence, antimicrobial resistance profile and comparison of selective plating media for the isolation of Salmonella in backyard chickens from Entre Rios, Argentina
(2018-02)This study was conducted to estimate the apparent prevalence of Salmonella spp. in birds kept under backyard system in Entre Ríos, Argentina, and determine the performance of two selective plating media used for Salmonella ... -
A fungal endophyte of a palatable grass affects preference of large herbivores
(2018-04)Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ... -
Prevalence, antimicrobial resistance profile and comparison of selective plating media for the isolation of Salmonella spp. in free-ranging waterfowl from Entre Rios, Argentina
(Oxford Academic Press, 2018-09)The present study was conducted to estimate the apparent prevalence of Salmonella spp. in free-ranging waterfowl that inhabitant Entre Ríos, Argentina, determine the antimicrobial resistance of the isolated, and compare ... -
Comparison of 7 culture methods for Salmonella serovar Enteritidis and Salmonella serovar Typhimurium isolation in poultry feces
(Oxford Academic Press, 2018-11)The present work compared 7 different culture methods and 3 selective-differential plating media for Salmonella ser. Enteritidis (SE) and S. ser. Typhimurium (ST) isolation using artificially contaminated poultry feces. ... -
Bienestar animal durante el período de engorde de bovinos
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2019)En Argentina los siste-mas de producción de carne se encuentran frente al desafío de intensificar los procesos para responder a la demanda mundial de proteínas de origen animal. Además de incrementar la producción, es ... -
Prevalence, antimicrobial resistance profile and comparison of methods for the isolation of salmonella in chicken liver from Argentina
(Elsevier, 2019-05)This study was conducted to estimate the apparent prevalence of Salmonella spp. in chicken livers obtained from markets in Entre Ríos, Argentina, using two culture methods (preenrichment and direct selective agar plating). ... -
Biofilm formation by Salmonella sp. in the poultry industry: Detection, control and eradication strategies
(Elsevier, 2019-05)Salmonella represents an important global public health problem and it is an emerging zoonotic bacterial threat in the poultry industry. Diverse registered human cases of salmonellosis shown poultry origins. Various control ... -
Patogenia y tipos de salmonella en las aves
(Cámara de Proveedores de Equipamiento Avícola y Porcino, 2019-09)El primer aislamiento de Salmonella fue realizado por el bacteriólogo norteamericano Daniel E. Salmon junto a su colaborador Theobald Smith en el año 1885a partir de cerdos afectados por peste porcina (Bhunia, 2008). ... -
Determination of inorganic arsenic in Argentinean rice by selective HGAAS: Analytical performance for paddy, brown and polished rice
(Elsevier, 2020)Inorganic As (iAs) species require strict monitoring in foodstuff due to their toxicity. Rice is of particular concern, with recent legislations establishing limits for these species. In this work we develop a method based ... -
A MODIS based tool to assess inundation patterns: an example for the Paraná Delta River
(Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)Wetlands are one of the most productive yet altered ecosystems due to human activities across the world. They rely largely on their water flow to provide several ecosystem functions. Then, to develop a land use plan that ... -
