Molecular and antigenic characterization of bovine Coronavirus circulating in Argentinean cattle during 1994–2010
Bok, Marina; Miño, Samuel; Rodriguez, Daniela; Badaracco, Alejandra; Nuñes, I.; Souza, Sibele P.; Bilbao, G.; Louge Uriarte, Enrique Leopoldo; Galarza, Roxana Ivon; Vega, Celina Guadalupe; Odeon, Anselmo Carlos; Saif, LInda J.; Parreño, Gladys Viviana (Elsevier, 2015-12)Bovine coronavirus (BCoV) is an important viral pathogen associated with neonatal calf diarrhea. Our aim was to investigate the incidence of BCoV in diarrhea outbreaks in beef and dairy herds from Argentina during 1994–2010. ... -
Molecular characterization of equine rotavirus group A detected in Argentinean foals during 2009–2014
Miño, Samuel; Aduriz Guerrero, Matías; Barrandeguy, Maria Edith; Parreño, Viviana (2017-12)Equine rotavirus group A (RVA) has been detected in several countries worldwide since its first detection in 1975. Currently, equine RVA is considered the major cause of dehydrating diarrhea in foals younger than 3 months, ... -
Molecular characterization of group A rotavirus strains detected in alpacas (Vicugna pacos) from Peru
Badaracco, Alejandra; Cordero, Aida; Vega, Celina Guadalupe; Bok, Marina; Zeller, Mark; Heylen, Elisabeth; Fernández, Gonzalo; Díez-Baños, Pablo; Morrondo, Patrocinio; Guevara, Héctor; Matthijnssens, Jelle; Parreño, Gladys Viviana (Microbiology Society, 2021-04)The alpaca is a very important social and economic resource for the production of fibre and meat for Andean communities. Peru is the main producer of alpacas. Group A rotavirus (RVA) has been sporadically detected in ... -
Molecular detection of bovine Noroviruses in Argentinean dairy calves : circulation of a tentative new genotype
Ferragut, Fátima; Vega, Celina Guadalupe; Mauroy, Axel; Conceição-Neto, Nádia; Zeller, Mark; Heylen, Elisabeth; Louge Uriarte, Enrique Leopoldo; Bilbao, Gladys; Bok, Marina; Matthijnssens, Jelle; Thiry, Etienne; Badaracco, Alejandra; Parreño, Gladys Viviana (2016)Bovine noroviruses are enteric pathogens detected in fecal samples of both diarrheic and non-diarrheic calves from several countries worldwide. However, epidemiological information regarding bovine noroviruses is still ... -
Molecular engineering improves antigen quality and enables integrated manufacturing of a trivalent subunit vaccine candidate for rotavirus
Dalvie, Neil C.; Brady, Joseph R.; Crowell, Laura E.; Tracey, Mary Kate; Biedermann, Andrew M.; Kaur, Kawaljit; Hickey, John M.; Kristensen II, D. Lee; Bonnyman, Alexandra D.; Rodriguez-Aponte, Sergio A.; Whittaker, Charles A.; Bok, Marina; Vega, Celina Guadalupe; Mukhopadhyay, Tarit K.; Joshi, Sangeeta B.; Volkin, David B.; Parreño, Gladys; Love, Kerry R.; Love, J. Christopher (BMC, 2021-05)Background: Vaccines comprising recombinant subunit proteins are well-suited to low-cost and high-volume production for global use. The design of manufacturing processes to produce subunit vaccines depends, however, on the ... -
Novel viruses determined using fecal virome analysis in the feces of foals with diarrea
Vega, Celina Guadalupe; Conceição-Neto, Nádia; Miño, Samuel; Zeller, Mark; Heylen, Elisabeth; Parreño, Viviana; Barrandeguy, Maria Edith; Matthijnssens, Jelle (2016)This study aims to expand the knowledge of viral species present in feces of foals suffering diarrhea using Next Generation Sequencing. This will be useful to further explore the role of new infectious agents in this illness ... -
Phylogenetic and structural analyses of equine rotaviruses : three possible geographically related lineages
Miño, Samuel; Parreño, Viviana; Barrandeguy, Maria Edith (2016)The structural analyses revealed that the aa substitutions in VP7 are in the antigenic sites and in the VP7:VP6 interaction region. In accordance, most of the aa changes in VP6 are in the top of the protein involving ... -
