BoLA-DRB3 exon2 polymorphisms among tuberculous cattle: Nucleotide and functional variability and their association with bovine tuberculosis pathology
(Elsevier, 2020-06)Bovine tuberculosis (bTB) is caused by Mycobacterium bovis and disseminated worldwide. In Argentina, the highest prevalence occurs in dairy areas. BoLA DRB3.2 is related to the adaptive immunity in mycobacterial infections. ... -
Comparación de la respuesta a la prueba de la tuberculina en dos sitios de aplicación en bovinos con tuberculosis
(INTA Ediciones, 2022-05)El diagnóstico de tuberculosis bovina (TB) se realiza a través de la prueba de la tuberculina (PT). En Argentina, el diagnóstico operativo de rutina se aplica en el pliegue ano caudal (PAC) interno utilizando PPD bovina ... -
Desarrollo de alternativas diagnósticas de tuberculosis bovina
(Universidad Nacional de Quilmes, 2015-02)En el siguiente trabajo se llevó cabo la puesta a punto y optimización de la técnica LAMP (del inglés loop-mediated isothermal amplification) para la detección de Mycobacterium bovis, agente etiológico de la tuberculosis ... -
Descripción de la evolución de tuberculosis en rodeos lecheros combinando el uso de IDR y ELISA
(Asosiación Argentina de Veterinarios de Laboratorios de Díagnóstico, 2021-11)La tuberculosis bovina (TB) produce un impacto negativo en la producción pecuaria y la salud pública. La respuesta inmune a la infección es predominantemente mediada por células. En ello se fundamenta el diagnóstico a ... -
Detection of Mycobacterium bovis in Bovine and Bubaline tissues using Nested-PCR for TbD1
(PLOS, 2014-03)In the present study, a nested-PCR system, targeting the TbD1 region, involving the performance of conventional PCR followed by real-time PCR, was developed to detect Mycobacterium bovis in bovine/bubaline tissue homogenates. ... -
Detection of Mycobacterium bovis–infected dairy herds using PCR in bulk tank milk samples
(Mary Ann Liebert Inc., 2012-02)Bovine tuberculosis (bTB) is a chronic and zoonotic disease due to Mycobacterium bovis. The tuberculosis eradication campaign carried out in Argentina has considerably improved the health situation of the herds. Here we ... -
Development and diagnostic validation of an ELISA based on an antigenic mixture for the detection of bovine tuberculosis
(Elsevier, 2020-02)Programs for the eradication of bovine tuberculosis (bTB) focus on the tuberculin skin test (TST) and slaughter of reactor cattle. However, the disease remains an animal health concern in several countries and improving ... -
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 ... -
Diagnóstico bacteriológico de tuberculosis bovina en bovinos reactores positivos a la prueba tuberculínica
(2018-04)Mycobacterium bovis es el agente causal de la tuberculosis bovina (TBB), enfermedad zoonótica que afecta la producción láctea y cárnica. En nuestro país, el diagnóstico se realiza a través de la prueba tuberculínica o ... -
Enzyme-linked immunosorbent assay as complement of intradermal skin test for the detection of mycobacterium bovis infection in cattle
(Elsevier, 2019-07)Diagnostic tests based on cell-mediated immunity are used in programs for the control and eradication of bovine tuberculosis (bTB), which is mainly caused by Mycobacterium bovis. Additional serological assays could be ... -
Epidemiology of Pig Tuberculosis in Argentina
(Frontiers Editorial, 2021-07)Bovine tuberculosis (bTB) is a disease caused mainly by the Mycobacterium bovis and that is endemic to livestock populations in most Latin American countries. Traditionally, bTB control programs are costly and targeted to ... -
