Risk factors of S. aureus intramammary infection in pre partum dairy heifers under grazing conditions and molecular characterization of isolates from heifers and cows
Camussone, Cecilia; Molineri, Ana Ines; Signorini, Marcelo; Neder, Veronica Elizabeth; Vitulich, Carlos Alberto; Calvinho, Luis Fernando (Cambridge University Press, 2020-02)The aims of the research reported here were to identify potential risk factors associated with the presence of Staphylococcus aureus intramammary infection (IMI) in pre partum dairy heifers on 17 dairy farms from three ... -
Single nucleotide polymorphisms in candidate genes and their relation with somatic cell scores in Argentinean dairy cattle
Nani, Juan Pablo; Raschia, Maria Agustina; Carignano, Hugo; Poli, Mario Andres; Calvinho, Luis Fernando; Amadio, Ariel (2015-11)The prevention and control of bovine mastitis by enhancing natural defenses in animals is important to improve the quality of dairy products. Mastitis resistance is a complex trait which depends on genetic components, as ... -
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 ... -
Survey of potential factors involved in the low frequency of CP5 and CP8 expression in Staphylococcus aureus isolates from mastitis of dairy cattle from Argentina, Chile, and Uruguay
Ambroggio, Maria Belen; Perrig, Melina Soledad; Camussone, Cecilia; Pujato, Nazarena; Bertón, Alicia; Gianneechini, Edgardo; Alvarez, Silvia; Marcipar, Ivan Sergio; Calvinho, Luis Fernando; Barbagelata, Maria Sol (2018-08)Staphylococcus aureus produces capsular polysaccharides (CPs) both in vivo and under defined culture conditions being serotypes 5 and 8 the most prevalent. S. aureus isolates that fail to produce CP5 or CP8 are defined as ... -
Susceptibilidad a antibióticos de Staphylococcus aureus aislados de mastitis bovina en lecherías de la cuenca central de Argentina
Neder, Veronica Elizabeth; Araujo, L.; Gianre, Vilma Rita; Calvinho, Luis Fernando (2016-09)La mastitis bovina causa cuantiosas pérdidas económicas al productor lechero y la industria láctea a nivel mundial. Staphylococcus aureus es uno de los principales patógenos mayores causantes de infecciones intramamarias, ... -
The association between mastitis and reproductive performance in seasonally-calved dairy cows managed on a pasture-based system = Asociación entre la mastitis y el desempeño reproductivo en rodeos lecheros Holstein de base pastoril y servicios estacionados
Gómez-Cifuentes, C.I.; Molineri, Ana Ines; Signorini, Marcelo; Scandolo Lucini, Daniel Edgardo; Calvinho, Luis Fernando (2014)The objective of this study was to assess association between clinical, subclinical mastitis, body condition score and the reproductive performance of cows under seasonally calving conditions in a pasture-based management ... -
Vigilancia de la resistencia antimicrobiana en animales: profundizar las iniciativas y ampliar las capacidades = Antimicrobial resistance surveillance in animals: to deepen initiatives and expand current capacities
Calvinho, Luis Fernando (Elsevier, 2021-06)La resistencia antimicrobiana (RAM) comenzó a ser detectada poco después de que el uso de antimicrobianos (AM) se difundiera para el tratamiento de infecciones en seres humanos y animales. Sin embargo, durante los últimos ... -
Which are important targets in development of S. aureus mastitis vaccine?
Scali, F.; Camussone, Cecilia; Calvinho, Luis Fernando; Cipolla, M.; Zecconi, A. (2015-06)Staphylococcus aureus represents one of the leading causes of mastitis in dairy cows worldwide. S. aureus IMI have variable outcomes due to virulence of the strain involved, immune defenses of the host, and by antibiotic ...
