(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, ... -
Vacuna “marcadora” contra el HVB-1
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Investigadores del INTA trabajaron en el desarrollo de un producto que previene una enfermedad que provoca importantes pérdidas económicas y que permite diferenciar entre animales vacunados e infectados. -
Immune cells transferred by colostrum do not influence the immune responses to foot-and-mouth disease primary vaccination
(Elsevier, 2019-09)Little is known about the influence of maternal antibodies and immune cells transferred through colostrum on the immune responses of calves to the currently used foot-and-mouth disease (FMD) vaccines. Here we evaluated the ... -
Immune mediators of pathology in neurobrucellosis: from blood to central nervous system
(Elsevier, 2019-07)Neurobrucellosis, which is the most morbid form of brucellosis disease, presents with inflammatory signs and symptoms. Recent experimental evidence clearly indicates that deregulation of astrocytes and microglia caused by ... -
Bovine leukemia virus infection in neonatal calves. Risk factors and control measures
(Frontiers Media, 2018-10)Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis (EBL). Although efficient eradication programs have been successfully implemented in most European countries and Oceania, BLV infection rates ... -
Detection of bovine leukemia virus RNA in blood samples of naturally infected dairy cattle
(MDPI, 2019-09)The viral expression in vivo, in bovine leukemia virus (BLV)-infected cattle, is considered to be restricted to extremely low levels, and the mitosis of infected B lymphocytes is regarded as the main mode of virus persistence ... -
Estimating the protection afforded by foot-and-mouth disease vaccines in the laboratory
(Elsevier, 2019-09)Foot-and-mouth disease (FMD) vaccines must be carefully selected and their application closely monitored to optimise their effectiveness. This review covers serological techniques for FMD vaccine quality control, including ... -
Caracterización del virus de influenza en cerdos en Argentina

Prevención y tratamiento de Rotavirus A mediante nanoanticuerpos VHH anti-VP6
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-06)La diarrea asociada a Rotavirus A (RVA) representa una de las principales causas de mortalidad infantil a nivel mundial. Si bien la vacunación masiva contra RVA ha logrado disminuir significativamente las muertes causadas ... -
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 ... -
