(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2017-08)Las diarreas neonatales representan uno de los síndromes clínicos más relevantes y frecuentes en potrillos menores de 6 meses de edad. Rotavirus grupo A (RVA) es el principal agente viral asociado a diarreas en potrillos, ... -
South American H4N2 influenza A virus improved replication in chicken trachea after low number of passages
(Frontiers Media, 2023-05)Introduction of influenza A viruses (FLUAV) into poultry from waterfowl is frequent, producing economic burden and increasing the probability of human infections. We have previously described the presence of FLUAV in wild ... -
Spontaneous virus reactivation in cattle chronically infected with bovine leukemia virus
(BioMed Central, 2019)Background: The absence of virus expression during the chronic stage of bovine leukemia virus (BLV) infection and its reactivation upon ex vivo culture has become a long-lived Dogma. During the chronic stage of BLV ... -
Stable infection of a bovine mammary epithelial cell line (MAC-T) with bovine leukemia virus (BLV)
(Elsevier, 2018)Bovine leukemia virus (BLV) is a retrovirus that affects cattle causing a lymphoproliferative disease. BLV infection has been associated with misbalance of the immune response causing a higher incidence of other infections. ... -
State of the art in anti-cancer mAbs
(2017-02-20)Following Milstein’s discovery, the monoclonal antibodies (mAbs) became a basic tool for biomedical science. In cancer field, since the first mAb was approved by the FDA a great improvement took place making of them a ... -
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 ... -
Structure-based drug design for envelope protein E2 uncovers a new class of bovine viral diarrhea inhibitors that block virus entry
(Elsevier, 2018-01)Antiviral targeting of virus envelope proteins is an effective strategy for therapeutic intervention of viral infections. Here, we took a computer-guided approach with the aim of identifying new antivirals against the ... -
Swine influenza: clinical, serological, pathological, and virological cross‐sectional studies in nine farms in Argentina
(International Society for Influenza and other Respiratory Virus Diseases, 2013-12)Background: Influenza A viruses (IAV) are important pathogens responsible for economic losses in the swine industry and represent a threat to public health. In Argentina, clinical, pathological, and virological findings ... -
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, ... -
The MVA vector expressing the F protein of bovine respiratory syncytial virus is immunogenic in systemic and mucosal immunization routes = El vector viral MVA que expresa la proteína F del virus respiratorio sincicial bovino es inmunogénico al administrarse por vía sistémica y por mucosas
(Elsevier, 2023-12)Bovine respiratory syncytial virus (BRSV) affects both beef and dairy cattle, reaching morbidity and mortality rates of 60---80% and 20%, respectively. The aim of this study was to obtain a recombinant MVA expressing the ... -
The role of viral particle integrity in the serological assessment of foot-and-mouth disease virus vaccine-induced immunity in swine
(Plos One, 2020-05)The efficacy of foot-and-mouth disease virus (FMDV) inactivated vaccines is mainly dependent on the integrity of the whole (146S) viral particles. If the intact capsids disassemble to 12S subunits, antibodies against ... -
