Bovine interferon lambda Is a potent antiviral against SARS-CoV-2 infection in vitro
(Frontiers Media, 2020-11)Interferon lambda (IFN-λ) is an antiviral naturally produced in response to viral infections, with activity on cells of epithelial origin and located in the mucosal surfaces. This localized activity results in reduced ... -
Optimized adenoviral vector that enhances the assembly of FMDV O1 virus-like particles in situ increases its potential as vaccine for serotype O viruses
(Frontiers Media, 2020-11)Although replication-defective human adenovirus type 5 (Ad5) vectors that express in situ the capsid-encoding region of foot-and-mouth disease virus (FMDV) have been proven to be effective as vaccines in relevant species ... -
Interferon lambda protects cattle against bovine viral diarrhea virus infection
(Elsevier, 2020-12)Interferon lambda (IFN-λ) plays an important role in inducing an antiviral state in mucosal surfaces and has been used as an effective biotherapeutic against several viral diseases. Here we performed a proof of concept ... -
A new molecular method for the rapid subtyping of bovine herpesvirus 1 field isolates
(Sage Publications, 2020-02)Bovine herpesvirus 1 (BoHV-1) causes several clinical syndromes in cattle worldwide. There are 3 subtypes of BoHV-1: 1.1, 1.2a, and 1.2b. Several molecular methods are commonly used in the detection and characterization ... -
Dynamics of neutralizing antibodies against Bovine respiratory syncytial virus in a dairy herd from Santa Fe Province, Argentina = Dinámica de anticuerpos neutralizantes contra el virus respiratorio sincitial bovino en un rodeo lechero de la provincia de Santa Fe, Argentina
(Elsevier, 2020-05)Bovine respiratory syncytial virus (BRSV) is one of the most relevant agents responsible for respiratory disease in cattle from both dairy and beef farms. BRSV is spread by horizontal contact causing a constant presence ... -
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 ... -
