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). ... -
Phenotyping and QTL mapping for cold tolerance at the germination and seedling stages in Argentine temperate rice
(Springer, 2020-07)In Argentina, the yield potential of rice (Oryza sativa L.) under suboptimal temperatures of temperate regions and during early sowing in tropical regions depends on its low-temperature germinability (LTG) and subsequent ... -
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). ... -
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 ... -
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 ... -
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 ... -
Producción de pollos parrilleros en países sudamericanos y planes sanitarios nacionales para el control de Salmonella en dichos animales = South American broiler production and national control plans for Salmonella in chickens
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2016-12)El crecimiento de la industria de pollos parrilleros ha sido importante en los países sudamericanos en los últimos años. Actualmente, se faenan más de 9.430 millones de pollos parrilleros en Sudamérica, siendo Brasil, ... -
Relationship of Salmonella infection and inflammatory intestinal response with hematological and serum biochemical values in laying hens
(2015-06)There are few studies about the blood serum of laying hens infected with Salmonella. The differential leukocyte count and blood chemistry values are an important aid in the diagnosis of human diseases, but blood parameters ... -
Relationship of Salmonella isolation with different serum and inflammatory intestinal parameters in natural fowl typhoid outbreaks from laying hens
(Elsevier, 2023-10)Our study was undertaken to determine the best samples and selective-differential plating media to be used for Salmonella spp. isolation. We also compared hematological and serum biochemical values, Salmonella biovar ... -
Remotely Sensed Spatiotemporal Variation in Crude Protein of Shortgrass Steppe Forage
(MDPI, 2022-02)In the Great Plains of central North America, sustainable livestock production is dependent on matching the timing of forage availability and quality with animal intake demands. Advances in remote sensing technology provide ... -
