Foot-and-mouth disease vaccination induces cross-reactive IFN-γ responses in cattle that are dependent on the integrity of the 140S particles
(2015-02)Interferon-γ (IFN-γ) recall responses against foot-and-mouth disease virus (FMDV) in FMD vaccinated cattle are utilized to study T-lymphocyte immunity against this virus. Here, a recall IFN-γ assay based on a commercial ... -
Fusion of foreign T-cell epitopes and addition of TLR agonists enhance immunity against Neospora caninum profilin in cattle
(2016)We demonstrated recently that immunization with recombinant Neospora caninum profilin (rNcPRO) induces limited protection and a regulatory T-cell response in mice. The aim of this study was to evaluate the immune response ... -
Immune Response and Partial Protection against Heterologous Foot-and-Mouth Disease Virus Induced by Dendrimer Peptides in Cattle
(2018-04)Synthetic peptides mimicking protective B- and T-cell epitopes are good candidates for safer, more effective FMD vaccines. Nevertheless, previous studies of immunization with linear peptides showed that they failed to ... -
Immune response and protection provided by live tachyzoites and native antigens from the NC-6 Argentina strain of Neospora caninum in pregnant heifers
(Elsevier, 2013-11)The aim of the present study was to compare the immunogenicity and protective efficacy of live tachyzoites and native antigen extract obtained from the NC-6 Argentina strain against vertical transmission of Neospora caninum, ... -
Inmunidad adaptativa y protectora contra el virus de la fiebre aftosa en bovinos : rol de las respuestas inmunes sistémica y de mucosas
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2018)La fiebre aftosa (FA) es una enfermedad viral infectocontagiosa de curso agudo que se caracteriza por producir lesiones vesiculares en tejidos de la mucosa oronasal (incluyendo lengua, encías y paladar), ubres, espacios ... -
Interferon lambda protects cattle against bovine viral diarrhea virus infection
(Elsevier, 2020-12)Interferon lambda (IFN-λ) plays an important role in inducing an antiviral state in mucosal surfaces and has been used as an effective biotherapeutic against several viral diseases. Here we performed a proof of concept ... -
Molecular and antigenic characterization of bovine Coronavirus circulating in Argentinean cattle during 1994–2010
(Elsevier, 2015-12)Bovine coronavirus (BCoV) is an important viral pathogen associated with neonatal calf diarrhea. Our aim was to investigate the incidence of BCoV in diarrhea outbreaks in beef and dairy herds from Argentina during 1994–2010. ... -
Multiplex PCR followed by restriction length polymorphism analysis for the subtyping of bovine herpesvirus 5 isolates
(BMC, 2013-06)Background: Several types and subtypes of bovine herpesviruses 1 and 5 (BoHV-1 and BoHV-5) have been associated to different clinical conditions of cattle, making type/subtype differentiation essential to understand the ... -
Protection induced by a glycoprotein E-deleted bovine herpesvirus type 1 marker strain used either as an inactivated or live attenuated vaccine in cattle
(BMC, 2014-01)Background: Bovine herpesvirus type 1 (BoHV-1) is the causative agent of respiratory and genital tract infections; causing a high economic loss in all continents. Use of marker vaccines in IBR eradication programs is widely ... -
Recent advances in BLV research
(MDPI, 2015-11)Different animal models have been proposed to investigate the mechanisms of Human T-lymphotropic Virus (HTLV)-induced pathogenesis: rats, transgenic and NOD-SCID/γcnull (NOG) mice, rabbits, squirrel monkeys, baboons and ... -
Stress response at different ages of weaning in cattle
(Infogain Publication, 2019-02)Weaning is an inherent husbandry practice in cow-calf beef production systems that impose physical, psychological, and nutritional stressors on calves. In order to characterize the main stressors and corresponding stress ... -
Systemic antibodies administered by passive immunization prevent generalization of the infection by foot-and-mouth disease virus in cattle after oronasal challenge
(2018-05)The role of passively transferred sera in the protection against aerogenous foot-and-mouth disease (FMD) virus infection in cattle was evaluated using vaccine-induced immune serum preparations obtained at 7 and 26 days ... -
Systemic Foot-and-Mouth Disease Vaccination in Cattle Promotes Specific Antibody-Secreting Cells at the Respiratory Tract and Triggers Local Anamnestic Responses upon Aerosol Infection
(2015-09)Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting biungulate species. Commercial vaccines, formulated with inactivated FMD virus (FMDV), are regularly used worldwide to control the disease. Here, ... -
TLR activation, immune response and viral protection elicited in cattle by a commercial vaccine against Bovine Herpesvirus-1
(Elsevier, 2022-01)The innate and acquired immune response induced by a commercial inactivated vaccine against Bovine Herpesvirus-1 (BoHV-1) and protection conferred against the virus were analyzed in cattle. Vaccination induced high levels ... -
Whole-genome analysis of natural interspecific recombinant between bovine alphaherpesviruses 1 and 5
(Elsevier, 2022-02)Bovine alphaherpesviruses 1 and 5 (BoHV-1 and BoHV-5) are closely related viruses that co-circulate in South America and recombine in the field. The complete genomes of three natural gB gene recombinant viruses between ...
