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 ... -
Late-gestation protein restriction negatively impacts muscle growth and glucose regulation in steer progeny
(Elsevier, 2019)The objective of this study was to determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes in glucose and insulin concentrations. At 129 d of gestation, ... -
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 ... -
Microbioma ruminal en vaca fresca bajo TMR con distintos niveles de almidón y tipo de carbohidratos: nivel Phylum
(Asociación Argentina de Producción Animal, 2022-11)El tipo de carbohidrato y niveles de almidón pueden inducir cambios en el ambiente del rumen y la estructura del microbioma. El objetivo fue analizar los principales Phylum en vacas frescas bajo TMR difiriendo en nivel de ... -
