Mouse model as an efficacy test for foot‐and‐mouth disease vaccines
(Wiley, 2020-04)Protection against foot‐and‐mouth disease virus (FMDV) has been linked to the development of a humoral response. In Argentina, the official control tests for assessing the potency of FMD vaccines are protection against ... -
Topical ganciclovir reduces viral excretion in mares with equine coital exanthema
(Elsevier, 2020-07)Equid alphaherpesvirus 3 (EHV-3) is the etiological agent of equine coital exanthema (ECE). Since no vaccines or antiviral therapies are available, prevention consists of clinical examination of mares and stallions before ... -
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 ... -
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 ... -
First characterization of a canine parvovirus causing fatal disease in coatis (Nasua nasua)
(Springer, 2019-12)A canine parvovirus (CPV)-like virus was detected by PCR and isolated from dead coatis in Argentina. Analysis of the full-length genome sequence revealed that it resembled CPV-but also contained a mutation in the VP2 protein ... -
Experimental infection of sheep with bovine leukemia virus (BLV): minimum dose of BLV-FLK cells and cell-free BLV and neutralization activity of natural antibodies = Infección experimental en ovinos con el virus de leucosis bovina: dosis mínima de células BLV-FLK y virus libre de células, y actividad neutralizante de anticuerpos naturales
(Elsevier España, 2019-12)Bovine leukemia virus (BLV) is an important cattle pathogen that causes major economic losses worldwide, especially in dairy farms. The use of animal models provides valuable insight into the pathogenesis of viral infections. ... -
Equine influenza virus in Asia: phylogeographic pattern and molecular features reveal circulation of an autochthonous lineage
(American Society for Microbiology, 2019-07)Equine influenza virus (EIV) causes severe acute respiratory disease in horses. Currently, the strains belonging to the H3N8 subtype are divided into two clades, Florida clade 1 (FC1) and Florida clade 2 (FC2), which emerged ... -
Seroprevalencia de leucosis enzoótica bovina en tambos del sur de la provincia de Córdoba, Argentina = Seroprevalence of enzootic bovine leucosis in dairy farms in the south of the province of Córdoba, Argentina
(2019-03)La Leucosis Enzoótica Bovina (LEB) afecta al tejido linfoide y el rasgo patológico distintivo es la transformación neoplásica de linfocitos B, su frecuencia es predominante en el ganado lechero adulto. Existen pocos estudios ... -
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 ... -
Molecular characterization of pestiviruses in fetal bovine sera originating from Argentina: evidence of circulation of HoBi-like viruses
(Frontiers Media, 2019-10)Serological evidence suggests that HoBi-like viruses, an emerging species within the Pestivirus genus of the Flaviviridae family, are in circulation in Argentina. While HoBi-like viruses were first isolated from Brazilian ... -
A direct high-throughput in Cell-ELISA for measuring infectivity of cytopathic and non-cytopathic bovine viral diarrhoea virus strains applied to the assessment of antiviral activity
(Elsevier, 2018-07-19)Low-cost high-throughput methods applicable to any virus strain are required for screening antiviral compounds against multiple field strains. Colorimetric cell-viability assays are used for this purpose as long as the ... -
Bovine coronavirus in Uruguay: genetic diversity, risk factors and transboundary introductions from neighboring countries
(Springer, 2019-11)Bovine coronavirus (BCoV) is a recognized cause of severe neonatal calf diarrhea, with a negative impact on animal welfare, leading to economic losses to the livestock industry. Cattle production is one of the most important ... -
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. ... -
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
