(PLOS, 2023-02)Bovine leukemia virus (BLV) is a retrovirus that causes malignant B-cell lymphoma in up to ten-percent of infected cattle. To date, the mechanisms of BLV linked to malignant transformation remain elusive. Although BLV-encoded ... -
Equid herpesvirus type 3 infection produces membrane-associated and secreted forms of glycoprotein G that are not required for efficient cell-to-cell spread of the virus in vitro
(Springer, 2023-04)The ORF 70 gene of equid alphaherpesvirus type 3 (EHV-3) encodes glycoprotein G (gG), which is conserved in the majority of alphaherpesviruses. This glycoprotein is located in the viral envelope and has the characteristic ... -
A novel MHC-II targeted BVDV subunit vaccine induces a neutralizing immunological response in guinea pigs and cattle
(Wiley, 2021-11)Bovine viral diarrhoea virus (BVDV) is a major cause of economic loss in the cattle industry, worldwide. Infection results in reduced productive performance, growth retardation, reduced milk production and increased ... -
Efficacy of prepartum vaccination against neonatal calf diarrhea in Nelore dams as a prevention measure
(BioMed Central, 2022-08)Background: Neonatal calf diarrhea (NCD) is the leading cause of calf morbidity and mortality in beef cattle. Cow’s vaccination in last stage of pregnancy is one of the most important measures to mitigate the risk of NCD ... -
Assessment on different vaccine formulation parameters in the protection against heterologous challenge with FMDV in cattle
(MDPI, 2022-08)Foot-and-mouth disease (FMD) remains one of the major threats to animal health worldwide. Its causative agent, the FMD virus (FMDV), affects cloven-hoofed animals, including farm animals and wildlife species, inflicting ... -
Development of a droplet digital PCR assay for quantification of the proviral load of bovine leukemia virus
(Sage Publications, 2022-05)Droplet digital PCR (ddPCR) is a highly sensitive tool developed for the detection and quantification of short-sequence variants—a tool that offers unparalleled precision enabling measurement of smaller-fold changes. We ... -
Establishment of a gnotobiotic pig model of Clostridioides difficile infection and disease
(BioMed Central, 2022-06)Clostridioides difficile (C. difficile) is a gram-positive, spore-forming, anaerobic bacterium known to be the most common cause of hospital-acquired and antibiotic-associated diarrhea. C. difficile infection rates are on ... -
Review of antiviral peptides for use against zoonotic and selected non-zoonotic viruses
(Elsevier, 2021-08)Viruses remain one of the leading causes of animal and human disease. Some animal viral infections spread sporadically to human populations, posing a serious health risk. Particularly the emerging viral zoonotic diseases ... -
Anthropogenic infection of domestic cats with SARS-CoV-2 alpha variant B.1.1.7 lineage in Buenos Aires
(Frontiers Media, 2022-03)SARS-CoV-2 reverse zoonosis, particularly to domestic animals, and the potential role of infected animals in perpetuating the spread of the virus is an issue of increasing concern. In this case report, we identified the ... -
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 ... -
Whole-genome analysis of natural interspecific recombinant between bovine alphaherpesviruses 1 and 5
(Elsevier, 2022-02)Bovine alphaherpesviruses 1 and 5 (BoHV-1 and BoHV-5) are closely related viruses that co-circulate in South America and recombine in the field. The complete genomes of three natural gB gene recombinant viruses between ... -
