Genetic and antigenic diversity of Bubaline alphaherpesvirus 1
(MDPI, 2025-08)Bubaline alphaherpesvirus 1 (BuHV-1) is a virus that belongs to the Varicellovirus genus within the Alphaherpesvirinae subfamily. While BuHV-1 infections in water buffaloes (Bubalus bubalis) are often subclinical, clinical ... -
Whole-transcriptome analysis of BLV-infected cows reveals downregulation of immune response genes in high proviral loads cows
(Frontiers Media, 2025-04)Bovine leukemia virus (BLV) is a retrovirus that infects cattle, causing bovine enzootic leukosis, a chronic disease characterized by the proliferation of infected B cells. BLV proviral load (PVL) is a key determinant of ... -
Pre-existing anti-inflammatory immune conditions influence early antibody avidity and isotype profile following Comirnaty® vaccination in mice
(MDPI, 2025-07)Background/Objectives: Vaccine immunogenicity is often suboptimal in vulnerable populations such as the elderly, infants, and individuals in low- and middle-income countries. One contributing factor may be pre-existing ... -
Assessing potential viral transmission between honeybees and hive-infesting ants using novel per-hive co-detection indices
(Springer Nature, 2025-06)Understanding which ant species interacting with honeybees can transmit or acquire viruses is crucial for managing honeybee health. Our objective was to develop a new methodology using two indices, based on a per-hive ... -
Optimized production of virus-like particles in a high-CHO-cell-density transient gene expression system for foot-and-mouth disease vaccine development
(MDPI, 2025-06)Background/Objectives: Foot-and-mouth disease virus (FMDV) poses a continuous threat to livestock health and agricultural economies. Current vaccines require high biosafety standards and are costly to produce. While novel ... -
Equine infectious anemia virus worldwide prevalence : A 24-year retrospective review of a global equine health concern with far-reaching implications
(Elsevier, 2025-07)Equine Infectious Anemia Virus (EIAV), the causative agent of Equine Infectious Anemia (EIA), presents a significant threat to equine populations worldwide. While local EIAV prevalence has been estimated in several studies, ... -
Reduction in acute bee paralysis virus Infection and mortality in honey bees (Apis mellifera) by RNA interference technology
(MDPI, 2025-05)In Argentina, various studies have reported the detection of multiple viruses in honey-producing and queen-rearing apiaries, with Aparavirus apisacutum, the causal agent of acute bee paralysis (ABP), demonstrating a ... -
Enhanced infectivity of bovine viral diarrhoea virus (BVDV) in arginase-producing bovine monocyte-derived macrophages
(Taylor & Francis, 2024)Macrophages are important cells of the innate immunity that play a major role in Bovine Viral Diarrhoea Virus (BVDV) pathogenesis. Macrophages are not a homogenous population; they exist in different phenotypes, typically ... -
