Characterization of immune response in Staphylococcus aureus chronically infected bovine mammary glands during active involution
Andreotti, Carolina Soledad; Baravalle, Celina; Sacco, Sofía Clara; Lovato, Melisa Belen; Pereyra, Elizabet Amanda Lorena; Renna, María Sol; Ortega, Hugo Hector; Calvinho, Luis Fernando; Dallard, Bibiana Elisabet (2017-10)The aim of this study was to characterize the immune response in Staphylococcus aureus chronically infected bovine mammary glands during active involution. Twenty-one Holstein non-pregnant cows in late lactation either ... -
Effect of different mini‐volume colloid centrifugation configurations on flow cytometrically sorted sperm recovery efficiency and quality using a computer‐assisted semen analyzer
Ferre, Luis Bernardo; Chitwood, James L.; Fresno, Cristóbal; Ortega, Hugo Hector; Kjelland, Michael E.; Ross, Pablo J. (Wiley, 2018-02)Straws of sex‐sorted sperm are usually packaged at a low concentration (e.g., ~2.1 × 106 sperm/ml) and cost significantly more than unsorted conventional semen from the same sire. In order to maximize the efficiency of ... -
Epidemiological Description of Cystic Ovarian Disease in Argentine Dairy Herds: Risk Factors and Effects on the Reproductive Performance of Lactating Cows
Cattáneo, Luciano; Signorini, Marcelo; Bertoli, José Gabriel; Bartolome, Julián Alberto; Gareis, Natalia Carolina; Díaz, Pablo Uriel; Bo, Gabriel Amilcar; Ortega, Hugo Hector (Wiley, 2014-12)To describe the epidemiology of cystic ovarian disease (COD), to find possible risk factors associated with the incidence of cysts and to analyse the impact of COD on the reproductive performance of dairy cows, databases ... -
Evaluación de indicadores metabólicos y bioquímicos sanguíneos en vacas en lactancia con Enfermedad Quística Ovárica = Evaluation of metabolic and biochemical blood parameters in lactating cows with Cystic Ovarian Disease
Cattáneo, Luciano; Barberis, Fabián C.; Stangaferro, Matías Luis; Signorini, Marcelo; Ruiz, Marcelo Fabián; Zimmermann, R.; Bo, Gabriel Amilcar; Hein, Gustavo Juan; Ortega, Hugo Hector (Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2013)El objetivo de este trabajo fue determinar y evaluar indicadores bioquímicos sanguíneos asociados a procesos metabólicos energéticos, proteicos, minerales y de funcionalidad hepática, junto con parámetros productivos y ... -
Intramammary infusion of Panax ginseng extract in bovine mammary gland at cessation of milking induces changes in the expression of toll-like receptors, MyD88 and NF-kB during early involution
Baravalle, Celina; Silvestrini, Paula; Cadoche, Mónica C.; Beccaria, Camila; Andreotti, Carolina Soledad; Renna, Maria Sol; Pereyra, Elizabet Amanda Lorena; Ortega, Hugo Hector; Calvinho, Luis Fernando; Dallard, Bibiana Elisabet (2015-06)The purposes of this study were to explore TLR2 and TLR4 participation and MyD88 and NF-κB activation in bovine mammary glands (BMG) treated with Panax ginseng (PG) at involution and verify the effect of PG in the cytokine ... -
Intramammary inoculation of Panax ginseng plays an immunoprotective role in Staphylococcus aureus infection in a murine model
Silvestrini, Paula; Beccaria, Camila; Pereyra, Elizabet Amanda Lorena; Renna, María Sol; Ortega, Hugo Hector; Calvinho, Luis Fernando; Dallard, Bibiana Elisabet; Baravalle, Celina (2017-12)The immunoprotective effect of Panax ginseng (Pg) extract was investigated in a mouse mastitis model. Lactating female mice were intramammarily inoculated with Pg or placebo, and then were challenged with S. aureus, while ... -
Panax ginseng extract reduces Staphylococcus aureus internalization into bovine mammary epithelial cells but does not affect macrophages phagocytic activity
Beccaria, Camila; Silvestrini, Paula; Renna, María Sol; Ortega, Hugo Hector; Calvinho, Luis Fernando; Dallard, Bibiana Elisabet; Baravalle, Celina (2018-09)Panax ginseng extract (PGe) has been shown to possess immunomodulatory effects in healthy dairy cows at drying off and to trigger an adequate immune response to protect from an experimental intramammary infection (IMI) ... -
Proliferation-apoptosis balance in Staphylococcus aureus chronically infected bovine mammary glands during involution
Andreotti, Carolina Soledad; Pereyra, Elizabet Amanda Lorena; Sacco, Sofía Clara; Baravalle, Celina; Renna, Maria Sol; Ortega, Hugo Hector; Calvinho, Luis Fernando; Dallard, Bibiana Elisabet (2017-05)The objective of this study was to determine whether Staphylococcus aureus chronic intramammary infection (IMI) influences expression of proteins related to regulation of proliferation and apoptosis processes and ... -
Staphylococcus aureus chronic intramammary infection modifies protein expression of transforming growth factor beta (TGF-β) subfamily components during active involution
Andreotti, Carolina Soledad; Pereyra, Elizabet Amanda Lorena; Baravalle, Celina; Renna, Maria Sol; Ortega, Hugo Hector; Calvinho, Luis Fernando; Dallard, Bibiana Elisabet (2014-02)The objectives of this study were to determine whether Staphylococcus aureus chronic intramammary infection (IMI) influences protein expression of TGF-β subfamily components and collagen I and to examine the histomorphometric ...
