Influence of corn silage supplementation before alfalfa grazing on ruminal environment in relation to the occurrence of frothy bloat in cattle
(Elsevier, 2007-07)Changes in the ruminal environment of cattle supplemented with corn silage (CS) before alfalfa grazing, in relation to the occurrence of frothy bloat, were evaluated. Six ruminally fistulated heifers were used in a crossover ... -
Interaction of bovine viral diarrhea virus with bovine cumulus–oocyte complex during IVM: Detection in permissive cells
(Elsevier, 2016-11)Structural changes in the zona pellucida (ZP) of bovine oocytes seem to modulate their interaction with various viral agents, facilitating the viral infection in in vitro production systems. To evaluate the susceptibility ... -
Involvement of toll-like receptors 3 and 7/8 in the neuropathogenesis of bovine herpesvirus types 1 and 5
(Elsevier, 2016-08)Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are closely related alpha-herpesviruses. BoHV-5 is the causal agent of non-suppurative meningoencephalitis in calves. BoHV-1 causes respiratory disease, abortions, genital ... -
Isolation of Neospora caninum from a beef cattle fetus from Argentina: Immunopathological and molecular studies.
(Elsevier, 2020-07)Neospora caninum is an important abortifacient agent affecting mainly cattle worldwide. The aim of the present work was to describe the histopathological findings in a naturally infected beef cow and its midterm fetus ... -
Ivermectin antiviral activity against Varicellovirus bovinealpha 1: assessment of intracellular drug accumulation in virus‑infected cells
(Springer, 2024-01)Varicellovirus bovinealpha 1 (formerly bovine alphaherpesvirus type 1, BoAHV-1) is associated with several syndromes in cattle, including respiratory disease and is one of the main agents involved in the bovine respiratory ... -
Lectin binding patterns and immunohistochemical antigen detection in placenta and lungs of Brucella abortus-bovine infected fetuses
(2018)Lectin binding relies on the affinity of these substances for specific terminal sugars. The method facilitates the identification of complex structures to which the terminal sugar attaches and may reveal physiological or ... -
Linoleic acid stimulates neutral lipid accumulation in lipid droplets of maturing bovine oocytes
(Elsevier, 2013-03-01)Linoleic acid (LA) is a polyunsaturated fatty acid present in high concentrations in bovine follicular fluid; when added to maturation culture media, it affects oocyte competence (depending on the type and concentration ... -
Methodological performance of selenium determination in ruminal fluid by hydride generation atomic absorption spectroscopy
(Ediciones INTA, 2021-04)Selenium (Se) is a trace element used by multiple enzymes. In ruminants, Se present in food is released to ruminal fluid allowing its absorption in the small intestine. Se release may be analysed by hydride generation ... -
Modelación productiva, económica y de gases de efecto invernadero de sistemas típicos de cría bovina de la pampa deprimida
(Universidad de Concepción. Facultad de Agronomía, Facultad de Ingeniería Agrícola y Facultad de Ciencias Veterinarias, Chile, 2019-03)El objetivo de este estudio de simulación fue evaluar la respuesta productiva, económica y de emisión de gases de efecto invernadero (GEI) en establecimientos típicos de la Pampa Deprimida de Argentina. Se utilizó ... -
Modulation of cathelicidins, IFNβ and TNFα by bovine alpha-herpesviruses is dependent on the stage of the infectious cycle
(Elsevier, 2019-07)Production of antimicrobial peptides cathelicidins, interferons and cytokines is an important feature in airway epithelial host defense. The innate immune response to alpha-herpesvirus infection at the sites of primary ... -
Modulation of granzymes mRNA expression in neural tissue of BoAHV-1 and BoAHV-5-infected cattle
(Elsevier, 2023-06)Bovine alphaherpesviruses (BoAHV)-1 and 5 are neurotropic viruses of cattle which differ in their neuropathogenic potential. BoAHV-5 is responsible for non-suppurative meningoencephalitis in calves while BoAHV-1 can ... -
Molecular Characterization of the First Bovine Herpesvirus 4 (BoHV-4) Strains Isolated from In Vitro Bovine Embryos production in Argentina
(Plos One, 2015-07-15)Bovine herpesvirus 4 (BoHV-4) is increasingly considered as responsible for various problems of the reproductive tract. The virus infects mainly blood mononuclear cells and displays specific tropism for vascular endothelia, ... -
Morphometric study of encephalic lesions in aborted bovine fetuses naturally infected by two subpopulations of Neospora caninum
(Springer, 2021-08)Neospora caninum is a major reproductive disease in cattle worldwide. In the Argentinian Humid Pampa, the seroprevalence, incidence of abortions, and economic losses due to neosporosis are considerably higher in dairy than ... -
Mycoplasma bovis-pneumonia and polyarthritis in feedlot calves in Argentina: First local isolation
(Asociación Argentina de Microbiología, 2022-05-21)Bovine respiratory disease (BRD) is one of the most frequent clinical concerns in weaned calves after their arrival at the feedlot. This work reports the first local isolation of Mycoplasma bovis from feedlot calves with ... -
Neospora caninum causes severe economic losses in cattle in the humid pampa region of Argentina
(Springer, 2013-06)This work estimates the economic losses due to Neospora abortions in the humid pampa region of Argentina. The total dairy and beef cattle population at risk of abortion is 1,771,326 and 9,726,684 head, respectively. In ... -
