Fasciola hepatica infection modifies IgG1 specific immune response to foot-and-mouth disease virus induced by vaccination
(Elsevier, 2024-01)Fasciola hepatica, a worldwide distributed helminth, has a robust immunoregulatory effect in the host, increasing the susceptibility to secondary infections. Foot and mouth disease (FMD) is a highly contagious acute vesicular ... -
Feasibility of polyclonal avian immunoglobulins (IgY) as prophylaxis against human norovirus infection
(MDPI, 2022-11)Background: Human norovirus (HuNoV) is the leading viral cause of diarrhea, with GII.4 as the predominant genotype of HuNoV outbreaks globally. However, new genogroup variants emerge periodically, complicating the development ... -
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 ... -
First report of Equine Parvovirus-Hepatitis (EqPV-H) in Argentina
(Elsevier, 2024-07)The novel Equine Parvovirus-Hepatitis (EqPV-H) was first identified in the serum and liver of a horse that died of equine serum hepatitis, also known as Theiler's disease. Several reports in recent years strongly suggest ... -
First report of isolation and molecular characterization of bubaline herpesvirus 1 (BuHV1) from Argentinean water buffaloes
(2014-11)Herpesviruses have mainly co-evolved with their hosts for millions of years. However, bovine herpesvirus 1 (BoHV1) and related ruminant alphaherpesviruses have been reported to cross the species barrier. Bubaline herpesvirus ... -
FMD empty capsids combined with the immunostant particle adjuvant -ISPA or ISA206 induce protective immunity against foot and mouth disease virus
(Elsevier, 2021-05)Foot and Mouth Disease Virus (FMDV) causes economy losses and is controlled by vaccination in many countries. Vaccine formulations based on empty capsids or Virus-Like Particles (VLPs) have the advantage of avoiding the ... -
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 ... -
Foot-and-mouth disease virus infection of dendritic cells triggers phosphorylation of ERK1/2 inducing class I presentation and apoptosis
(Elsevier, 2015-09)Foot-and-mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed animals. This pathology is caused by foot-and-mouth disease virus (FMDV). Over time, the development of vaccines to prevent the spread of ... -
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 ... -
Galectin‐8 activates dendritic cells and stimulates antigen‐specific immune response elicitation
(2017-11)Galectin‐8 (Gal‐8) is a mammalian β‐galactoside‐binding lectin, endowed with proinflammatory properties. Given its capacity to enhance antigen‐specific immune responses in vivo, we investigated whether Gal‐8 was also able ... -
Genetically diverse herpesviruses in South American Atlantic coast seabirds
(2017)Different herpesviruses have been associated with respiratory and enteric disease and mortality among seabirds and waterfowl. In 2011, a respiratory disease outbreak affected 58.3% (98/168) of the Magellanic penguins ... -
Heat‑related massive chick mortality in an Imperial Cormorant Leucocarbo atriceps colony from Patagonia, Argentina
(Springer, 2022-02)Climate change has exacerbated the frequency and severity of heat waves, which on occasion lead to mass mortalities. Here, we report a massive mortality event in Imperial Cormorant Leucocarbo atriceps chicks that took place ... -
Herpesvirus bovino 1 (BoHV-1): actualización de las cepas circulantes en Argentina = Bovine herpesvirus 1 (BoHV-1): update of circulating strains in Argentina
(Universidad Nacional del Nordeste, 2018-06)BoHV-1 genera en el ganado bovino una amplia gama de manifestaciones clínicas, tales como la rinotraqueítis infecciosa bovina, abortos y vulvovaginitis pustular infecciosa, que dependen de la virulencia del virus y del ... -
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 ... -
Human rotavirus replicates in salivary glands and primes immune responses in facial and intestinal lymphoid tissues of gnotobiotic pigs
(MDPI, 2023-08)Human rotavirus (HRV) is a leading cause of viral gastroenteritis in children across the globe. The virus has long been established as a pathogen of the gastrointestinal tract, targeting small intestine epithelial cells ... -
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 ... -
Immune Response and Partial Protection against Heterologous Foot-and-Mouth Disease Virus Induced by Dendrimer Peptides in Cattle
