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 and evaluation of a blocking ELISA for serological diagnosis of equine infectious anemia
(Springer, 2023-04)Equine infectious anemia (EIA) is an important viral disease characterized by persistent infection in equids worldwide. Most EIA cases are life-long virus carriers with low antibody reactions and without the appearance 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 an IgY-Based treatment to control bovine Coronavirus diarrhea in dairy calves
(MDPI, 2023-03)Bovine Coronavirus (BCoV) is a major pathogen associated with neonatal calf diarrhea. Standard practice dictates that to prevent BCoV diarrhea, dams should be immunized in the last stage of pregnancy to increase BCoV-specific ... -
Development of an Indirect ELISA Based on a Recombinant Chimeric Protein for the Detection of Antibodies against Bovine Babesiosis
(2018)The current method for Babesia spp. serodiagnosis based on a crude merozoite antigen is a complex and time-consuming procedure. An indirect enzyme-linked immunosorbent assay (iELISA) based on a recombinant multi-antigen ... -
Development of nanobodies against Mal de Río Cuarto virus major viroplasm protein P9‑1 for diagnostic sandwich ELISA and immunodetection
(Springer Nature, 2021-10)Mal de Río Cuarto virus (MRCV) is a member of the genus Fijivirus of the family Reoviridae that causes a devastating disease in maize and is persistently and propagatively transmitted by planthopper vectors. Virus replication ... -
Enhanced sensitivity in detection of antiviral antibody responses using biotinylation of foot-and-mouth disease virus (FMDV) capsids
(Elsevier, 2017-11)Analysis of the immune response to infection of livestock by foot-and-mouth disease virus (FMDV) is most often reported as the serum antibody response to the virus. While measurement of neutralizing antibody has been ... -
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 ... -
