Impact of different foot and mouth disease vaccine schemes in cross-neutralization against heterologous serotype O strains in cattle
(MDPI, 2024-11)The high antigenic variability of the foot-and-mouth disease virus (FMDV) represents a challenge for developing prophylactic strategies, stressing the need for research into vaccines offering broad protection against a ... -
Equine coital exanthema : New approaches to minimise the negative impact on the equine industry
(Wiley, 2024-10)Equine coital exanthema (ECE), caused by Equid alphaherpesvirus 3 (EHV-3), is a highly contagious, venereally transmitted mucocutaneous disease, characterised by the formation of papules, vesicles, pustules and ulcers on ... -
Outbreak of Western equine encephalitis virus infection associated with neurological disease in horses following a nearly 40-year intermission period in Argentina
(MDPI, 2024-10)Western equine encephalitis virus (WEEV) is a mosquito-borne arbovirus (genus Alphavirus, family Togaviridae) that has re-emerged in South America in late 2023, causing severe disease in both horses and humans after a ... -
The complete genome of equid herpesvirus‑1 (EHV‑1) feld isolates from Argentina reveals an interspecifc recombinant strain
(Springer, 2024-10)The Equid alphaherpesvirus type 1 (EHV-1) infection can have devastating economic consequences in the horse industry due to large-scale outbreaks of abortions, perinatal foal mortality, and myeloencephalopathy. The present ... -
Chronic NOD2 stimulation by MDP confers protection against parthanatos through M2b macrophage polarization in RAW264.7 cells
(Elsevier, 2024-09)Innate immune cells show enhanced responsiveness to secondary challenges after an initial non-related stimulation (Trained Innate Immunity, TII). Acute NOD2 activation by Muramyl-Dipeptide (MDP) promotes TII inducing the ... -
Detection and characterization of Deformed Wing Virus (DWV) in apiaries with stationary and migratory management in the province of Entre Ríos, Argentina
(Springer Nature, 2024-07)In Argentina, migratory activity in search of floral diversity has become a common approach to maximizing honey production. The Entre Ríos province possesses a floral diversity that allows beekeepers to perform migratory ... -
