Detection of ovine antibody to Brucella ovis by Indirect Enzyme Immunoassay
(Taylor & Francis Group, 2007)Because some batch-to-batch variation in the preparation of rough lipopolysaccharide (RLPS) from Brucella ovis has been experienced, several protocols were tested to establish the most reliable method for detection of ... -
Development and evaluation of a low cost IgG ELISA test based in RBD protein for COVID-19
(Elsevier, 2022-01)Serology tests for SARS-CoV-2 have proven to be important tools to fight against the COVID-19 pandemic. These serological tests can be used in low-income and remote areas for patient contact tracing, epidemiologic studies ... -
Development and validation of a novel ELISA for the detection of Neospora caninum antibodies in bovine sera
(Annex Publishers, 2019-08-26)Neospora caninum is a world-wide distributed apicomplexan parasite, causative agent of bovine neosporosis, which is one of the major causes of reproductive losses in cattle affecting both dairy and beef industries. Several ... -
Development of a lateral flow immunochromatography test for the rapid detection of bovine tuberculosis
(Elsevier, 2021-04)Detection of specific antibodies would be a useful test strategy for bovine tuberculosis (bTB) as a complement to the single skin test. We developed a lateral flow immunochromatography (LFIC) test for rapid bTB detection ... -
Development of an antigen-biotin conjugate with a protein bridge and its application for the development of an enzyme immunoassay
(Taylor & Francis, 2012-12)Antigens with aromatic amino groups can be conjugated to proteins by a diazo bond. This property was used to synthesise an antigen-biotin conjugate using bovine serum albumin (BSA) as a bridge, and tested this conjugate ... -
Diagnóstico serológico de brucelosis en caprinos: comparación de técnicas = Serological diagnosis of brucellosis in goats: comparison of techniques
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2015)La producción caprina representa un rubro importante dentro del sistema agropecuario de la República Argentina y la brucelosis causada por Brucella melitensis es considerada el motivo principal de los problemas reproductivos ... -
Evaluation and comparison of serological methods for the detection of bovine neosporosis in Argentina = Evaluación y comparación de pruebas serológicas para la detección de la neosporosis bovina en Argentina
(Asociación Argentina de Microbiología, 2015-12)Neospora caninum is a protozoan parasite that causes abortion and important economic losses in cattle worldwide. The accurate diagnosis of neosporosis is essential for management and control measures. The aims of this study ... -
Evaluation of three different antigens in an indirect enzyme-linked immunoassay for the detection of antibodies against Brucella abortus SRB51 in vaccinated heifers
(Elsevier, 2009)The live attenuated Brucella abortus SRB51 (SRB51) is a partial O-chain-deprived mutant. The relative lack of the polysaccharide prevents it from inducing antibodies detectable by most of the serological tests used for the ... -
First report of rice stripe necrosis virus in Argentina
(Elsevier, 2018-12)Since 2008/2009, we have seen symptoms of viral infection in rice plants from crop regions in Argentina. The main objective of this work was to identify the causal agent of the rice plants' crinkling. We therefore analyzed ... -
Identification of the Apa protein secreted by Mycobacterium avium subsp. paratuberculosis as a novel fecal biomarker for Johne's disease in cattle
(Oxford University Press, 2018-08)Paratuberculosis (PTB) or Johne's disease is a chronic intestinal infection of ruminants, caused by Mycobacterium avium subsp. paratuberculosis. The shedding of mycobacteria in the feces starts at the initial stages and ... -
Lectin binding patterns and immunohistochemical antigen detection in placenta and lungs of Brucella abortus-bovine infected fetuses
