Evaluation of total white blood cell count as a marker for proviral load of bovine leukemia virus in dairy cattle from herds with a high seroprevalence of antibodies against bovine leukemia virus
(2013-05)Objective—To determine the reference interval for WBC counts in Holstein dairy cows from herds with high seroprevalence for anti–bovine leukemia virus (BLV) antibodies, analyze the correlation of total WBC counts and blood ... -
Dynamics of perinatal bovine leukemia virus infection
(BioMed Central, 2014)Bovine leukemia virus (BLV) is highly endemic in many countries, including Argentina. As prevention of the spread from infected animals is of primary importance in breaking the cycle of BLV transmission, it is important ... -
Comparative histopathological and immunological study of two field strains of chicken anemia virus
(BioMed Central, 2014-10)Infection of poultry with chicken anemia virus (CAV) is implicated in several field problems in broiler flocks due to the immunosuppression generated and, consequently, the increased susceptibility to secondary infections. ... -
Controlling Rotavirus-associated diarrhea: Could single-domain antibody fragments make the difference? = Hacia el control de la diarrea por rotavirus A: ¿podrían los nanoanticuerpos VHH marcar la diferencia?
(Asociación Argentina de Microbiología, 2015-10)Group A Rotavirus (RVA) remains a leading cause of severe diarrhea and child mortality. The variable domain of camelid heavy chain antibodies (VHH) display potent antigen-binding capacity, have low production costs and are ... -
The efficacy of ELISA commercial kits for the screening of equine infectious anemia virus infection = Eficacia de ensayos de ELISA comerciales para el screening de infección por el virus de la anemia infecciosa equina
(Elsevier España, 2015-03)The most used and reliable indicator of equine infectious anemia virus (EIAV) infection is the detection of its specific antibodies in horse serum. In the present study, the performance of two commercial ELISA tests for ... -
Quantitation of cytokine gene expression by real time PCR in bovine milk and colostrum cells from cows immunized with abovine rotavirus VP6 experimental vaccine
(Elsevier, 2013-10)In a previous work, VP6 recombinant protein was produced using baculovirus system and it was evaluated in a colostrum-deprived calf model. This vaccine was able to protect calves against viral challenge without inducing ... -
Bovine respiratory syncytial virus seroprevalence and risk factors in feedlot cattle from Córdoba and Santa Fe, Argentina = Seroprevalencia del virus respiratorio sincicial bovino y factores de riesgo asociados en engordes a corral de Córdoba y Santa Fe, Argentina
(2018-09)Bovine respiratory syncytial virus (BRSV) is one of the causative agents of respiratory disease in cattle all over the world, leading to important economic losses. The aim of this work was to determine the seroprevalence ... -
Passive immunity to control Bovine coronavirus diarrhea in a dairy herd in Argentina = Inmunidad pasiva en el control de la diarrea por coronavirus bovino en un rodeo lechero de Argentina
(2018)Bovine coronavirus (BCoV) is a viral enteric pathogen associated with calf diarrhea worldwide being, in Argentina, mostly detected in dairy husbandry systems. The aim of the present work was to study if maternal IgG1 ... -
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 ... -
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, ... -
Early Adaptive Immune Responses in the Respiratory Tract of Foot-and-Mouth Disease Virus-Infected Cattle
(2013-03)Foot-and-mouth disease (FMD) is a highly contagious viral disease which affects both domestic and wild biungulate species. This acute disease, caused by the FMD virus (FMDV), usually includes an active replication phase ... -
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 ... -
Influence of antibodies transferred by colostrum in the immune responses of calves to current foot-and-mouth disease vaccines
(2014-11-12)Immunity to currently used oil-adjuvanted inactivated vaccines against foot-and-mouth disease virus (FMDV) has been studied in detail in adult animals; however, the influence of maternally derived antibodies transferred ... -
Heterogeneity in the antibody response to foot‐and‐mouth disease primo‐vaccinated calves
(2015-06)Foot‐and‐mouth disease (FMD) vaccines are routinely used as effective control tools in large regions worldwide and to limit outbreaks during epidemics. Vaccine‐induced protection in cattle has been largely correlated with ... -
