Mycobacterium bovis deleted in mce2 and phoP loci protects C57BL/6 mice against tuberculosis
(2016)Here we confirm the efficacy of MbΔmce2-phoP to protect mice against bTB challenge and we demonstrated that this new attenuated strain is safer than our previous bTB vaccine MbΔmce2. Altogether ... -
Mycotoxicoses of ruminants and horses
(Sage Publications, 2013-11)In the current study, mycotoxicoses of ruminants and horses are reviewed, with an emphasis on the occurrence of these diseases in South America. The main mycotoxicoses observed in grazing cattle include intoxications by ... -
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 ... -
Neospora caninum serostatus is affected by age and species variables in cohabiting water buffaloes and beef cattle
(Elsevier, 2014-07-14)The aim of this study was to investigate how Neospora caninum serostatus may be affected by variables such as host species (water buffaloes or cattle) and age in animals cohabiting in the same ranch. A convenience ... -
Neosporosis epidémica y endémica: descripción de dos eventos en bovinos para cría = Endemic and epidemic bovine neosporosis: description of two events in beef cattle
(Elsevier, 2014-12)El objetivo de este trabajo es describir dos eventos producidos en la provincia de Buenos Aires en los cuales Neospora caninum estuvo asociado a la ocurrencia de abortos en bovinos de cría para carne. En uno de ellos se ... -
Pathogenicity of Nc-Bahia and Nc-1 strains of Neospora caninum in experimentally infected cows and buffaloes in early pregnancy
(Springer, 2014-04)Neospora caninum is a protozoan parasite known as an important cause of bovine abortion worldwide. Little is currently known about how different strains of N. caninum vary in their pathogenicity. In this study, we compared ... -
Phenotypic characterization of immune cells in fetal tissues of cattle immunized and challenged with Neospora caninum
(Elsevier, 2019-11)The purpose of this work was to characterize the cellular phenotype in inflammatory infiltrates of fetal tissues from pregnant heifers immunized and experimentally challenged with Neospora caninum. Fetuses from 20 heifers ... -
Respiratory distress in Holstein cows fed corn silage: case report
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2023-11-28)An outbreak of respiratory distress was observed in Holstein cows immediately after consuming a new batch of corn-silage, presumably due to the presence of pneumotoxic gases. Signs were observed in 10% of the cows, and ... -
