Characterization of lesions of nutritional congenital goitre in cattle
Colque Caro, Luis Adrián; Acuña, Francisco; Aguirre Castro, Laura Sabrina; Avellaneda Cáceres, Agustín; Barbeito, Claudio G.; Signorini Porchiett, Marcelo Lisandro; Moore, Prando Dadin; Micheloud, Juan Francisco (Elsevier, 2023-08-18)There are few studies that classify and characterize the morphometric and immunohistochemical features of goitre in bovine thyroid glands (TGs). We investigated 39 bovine TGs (fetuses [9], stillbirths [18], neonates [12]) ... -
Combination of organic acids and low-dose gamma irradiation as antimicrobial treatment to inactivate Shiga toxin-producing Escherichia coli inoculated in beef trimmings: Lack of benefits in relation to single treatments
Cap, Mariana; Cingolani, Celeste; Lires, Carla; Mozgovoj, Marina Valeria; Soteras, Trinidad; Sucari, Adriana; Gentiluomo, Jimena; Descalzo, Adriana Maria; Grigioni, Gabriela Maria; Signorini, Marcelo; Horak, Celina; Vaudagna, Sergio Ramon; Leotta, Gerardo (Plos ONE, 2020-03-26)The aim of this study was to assess the efficacy of lactic acid (LA), caprylic acid (CA), high- (HDI) and low- (LDI) dose gamma irradiation and LDI combined with LA or CA on the inactivation of a pool of Shiga toxin-producing ... -
Comparison of two coprological methods for the diagnosis of Eurytrema ssp. in cattle and sheep
Olmos, Leandro Hipolito; Pantiu, Andrea Julia; Avellaneda Cáceres, Agustín; Valencia, P.N.; Cayo, P.N.; Signorini Porchiett, Marcelo Lisandro; Micheloud, Juan Francisco (Cambridge University Press, 2022-07-27)Eurytrematosis is a disease caused by flukes of the genus Eurytrema.
